PSC-CS Laser

STAND ALONE, IR THERMOMETER?S DUAL LASERS, MAKE FOCUSING AND TARGET SIZE DETERMINATION EASY.

Knowing the precise point or area of a target to be monitored when using infrared thermometers for temperature measurement is critical to measurement accuracy. Process Sensors? newly released model PSC-CS-Laser thermometer series eliminates guesswork by using two, built-in, bright red lasers.

At the focus distance, the laser beams converge to form a single spot on the target. At distances other than the focus length, individual laser spots delineate the measured target size diameter. The model PSC-CS-Laser series are self contained pyrometers constructed from rugged stainless steel that can be configured for 2 wire loop powered or 4 wire operation when utilizing dual lasers for targeting.

The high accuracy infrared temperature sensor can operate in ambient temperatures up to 185?F (85?C) without the need for cooling, offers fast speed of response and high resolution optics with selectable fixed focus distances for small target sizes from 0.020? (0.5mm) in diameter. The rugged stainless steel housing with companion heavy duty cooling jacket with air purge, stands up to the most severe industrial environments.

Spectral responses of 8 to 14? with a temperature range of -50 to 975?C, or 1.6? with a temperature range of 385 to 1600?C, suit the loop powered, compact sensors to a wide range of applications such as induction heating, metal processing, semiconductors, paper, plastics, webs, ovens, furnaces, glass, ceramics, thermoforming, food, powders, liquids, hot material /aggregate on conveyors etc. Outputs are analog 4 to 20mA, 0-30V open collector, used for alarm and digital uni/bidirectional, 9.6kBaud, communication.

Measurement parameters such as emissivity can be set manually on the IR sensor, or via PSC Connect software with optional USB connector. The software also facilitates the set-up of peak, valley and averaging functions, graphic display of temperature trends, and data logging with a 1ms response time.

Moisture Measurement in Particleboard

The continuous measurement of moisture is a key consideration in the production of particleboard. The proper moisture level of particleboard guarantees safety and high product quality.

Particleboard Production Process

Raw materials are passed through chippers, flakers and size reduction mills to create a relatively uniform particle size. The mix passes through screeners which remove fines, before they enter the dryer. During the drying phase, the moisture content is reduced from a high of 75% to less than 10% moisture. The dried material is then graded and separated into core and surface product. The products pass through different blenders as a function of their different requirements for resin. After the blender, the furnish is formed then pressed into boards.

Measurement Location and Installation

Measurements can be made at five different location; on the raw material, pre-dryer, post dryer, post blender and on the former. The sensor can be positioned to look through a viewing window at a 15? angle in the side of a storage bin of gravity chute. The sensor can also be positioned over a conveyor/weigh belt, or on the side of a formed mat. Whatever the location the moisture sensor should be mounted approximately 200cm from the product. The most common location for a moisture sensor is over the forming line.


Self-Contained, Non-Contact Infrared Temperature Sensor

Process Sensors Corporations significant design innovations and installation simplicity combined with formidable industrial packaging allows for seamless integration into existing systems. The new DT-44G and DT-44GH line of digital, self-contained, non-contact infrared temperature sensors are exceptional performers in glass and solar cell production applications for measurement of glass surfaces and substrate materials. They have also proven to be equally beneficial in the ceramics and semiconductor industries.

Paper Converting Process

The continuous measurement of moisture in the paper converting process is a key consideration. The proper moisture level can have a large impact on the curl properties of the paper. By installing the MCT Moisture Transmitter in line, a converter can continuously monitor the moisture level and manually or automatically control the moisture content.

Installation

The Transmitter is routinely used to measure finished moisture prior to wind up. It is also used for measurement and control of water addition by various means: spray addition, steam, rolls, and knives. The location is dependent to a large degree on the availability of space on the converting machinery. The location is also determined by the requirements of the control strategy. PSC can make the appropriate suggestions on proper location upon discussion. The Transmitter should be mounted about 12 from the web. This distance can be optimized for machine limitations. If the paper is glossy or wet the Transmitter should be angled about 15 degrees off of the perpendicular, relative to the web. It is important to keep environmental temperature in mind. If the Transmitter is used in close proximity to a dryer outlet or heater, cooling may be required. Air or watercooling devices, supplied by PSC, can be used for cooling. An air purge assembly over the optical window may be required, especially if the environment is steamy enough to cause condensation on the window.

Measurement Performance

Moisture in paper is a very well understood and documented application.
Measurement wavelengths, algorithms, and sensor optical parameters are pre-set at the PSC factory. Calibrations are also pre-set at the factory. Typical accuracy is about ?0.2% moisture. It is possible to improve that with careful sample handling and lab methodology. Very different basis weights can require different calibration settings. The same is true for dramatic color differences. PSC can advise. Typical analog output range is 0-10% moisture. The Transmitters output range can easily be adjusted for the best PLC or controller operation. Process Sensors is very experienced with the requirements of this application.

Moisture In Finished Tobacco

The continuous measurement of moisture in tobacco is a key consideration in the production of tobacco.? The proper moisture level of finished tobacco has an impact on production speed and tobacco quality.? By installing the MCT360-T in the processing area, a manufacturer can continuously monitor the moisture content and either manually or automatically make control decisions.

Installation

The MCT360-T is typically installed over a full conveyor prior to the making area.? ? The MCT should be positioned about 8″ from the tobacco bed and perpendicular to the moving conveyor.? It is always to important to make sure during the MCT’s installation there are no gaps or interruptions in the product flow.

Moisture measurement in finished tobacco is a vey well understood and documented application.? NIR wavelengths, calibrations,? algorithms and sensor optical parameters are pre-set at the PSC factory.

Attention Snack Food Manufacturers: Seasoning and Flavoring Application

NIR Analyzers have been assets to the Snack Food Industry for a number of years.? They have been widely used and are an accepted method of analysis in many environments and used for a variety of applications.

One interesting application is the automatic controls of flavoring addition for both cheese curls and popcorn.? An NIR sensor is installed on a conveyor after a tumbler.? The tumbler applies the flavoring in a form of a slurry and the NIR sensor actually measures the oil content of the slurry.? The amount of oil in the slurry has a direct relationship to the total amount of flavoring being applied.? The NIR sensor’s 4-20mA output is connected into a process controller that automatically adjusts the amount of flavoring applied by manipulating a pump to a desired set point.

Soup Packaging

Soup in polyethylene bags exiting a chiller and entering the packaging line, monitored by Process Sensor?s infrared thermometer model PSC SSS-Laser.

The Application

In the Food Industry, plant cleanliness and maintaining a bacteria free product are primary concerns. To eliminate bacterial development, it is critical to maintain foodstuffs and processing equipment at temperatures below 41?F.

Truesoups, a division of H.J. Heinz Co., ( SIC code 209903 Food products ) provides frozen, ready to heat and serve soups. At its manufacturing plant located in Kent, Washington State, soup is conveyed in polyethylene bags to a chiller.

After exiting the chiller, the bags pass into the field of view of a Process Sensors model PSC SSS-Laser infrared thermometer with a spectral response of 8 to14?.

Clear polyethylene plastic transmits 90% of IR energy in that waveband. The spectral response also avoids the atmospheric moisture absorption bands that are present at either side of it. This feature can be important in food processing where steam and water vapor is often present.

At this time, the customer is using only the 4 -20mA output to display the temperature on an indicator, but according to Process Engineer, Dave Jametski, he plans to employ the Ethernet output for computer data acquisition using Process Sensor?s CompactConnect software package.

Jametski says that the stored data will be an essential tool in investigating product problems that often may only come to light after manufacture.

Application Tips

Food processing plants require some unique factors to be taken into account. First is the presence of steam and water vapor in the atmosphere. This may require air purging, but the source of air must be pure so as not to contaminate the product.? ? It is often better to use nitrogen for this reason.

If water-cooling is required, for meat cooking applications, care must be taken not to overcool, as this will cause condensation to form on the lens. The sensor should be positioned so that condensate does not drip onto the
product or the cooling flow must be regulated, thereby not exceeding the dew point that would cause condensation.

Food processes are frequently hosed down with hot water, or in some cases steam, so it is important to seal signal and power cable entry points. A long sight tube or gate valve can be used to protect the lens if necessary.

The Market

Applications for infrared thermometers in food processing are abundant and varied; from monitoring frozen fish on fish-stick cut up lines, to measuring and controlling sealing jaws on plastic bag sealing machines.

Processes are usually highly automated, with limited operator attendance, increasing the importance of monitoring, control and data acquisition instrumentation. OEM?s include continuous and static oven builders,
microwave and steam-kettle cooker manufacturers. Mixer and mechanical handling companies are also good prospects.

Process Sensors Model PSC-SS-Laser, with laser aiming defines the measurement area at any distance.

Instrument Selection

Process Sensors Model PSC-SS-Laser with a 75:1 FOV is used for continuous measurement at the chiller exit. Outputs: 4 -20mA, T/C and optional Ethernet.

Process Sensors Portable Model PSC-PSLT is recommended for hand held measurements.
