Sensor
Either a cast aluminium MCT
360, ATEX 22-MCT 360 or MCT
330HD.
The MCT
330HD helps avoid the necessity for a vortex cooler and
air supply in situations where the ambient temperature is
higher than 50°C, but lower than 65°C, it is also
more practical in locations where the gauge may be hosed down.
The Atex
22-MCT 360 gauge is required for
installations where the dust environment is potentially hazardous.
Accessories
The MCT
360 is built to withstand conditions both inside and outside
a plant, and has options that may be fitted should temperature
conditions become extreme; a heat
blanket can be fitted inside the
gauge to ensure the internal temperature of the gauge doesn’t
drop below x°C, and the addition of a vortex
cooler and cooling panel will keep
the gauge performing under ambient conditions of up to 80°C.
The enclosure is IP65 rated, and as such, is dust and splashproof,
but if the gauge is to be mounted outside it will benefit
from a cover to protect it from driving rain, snow or direct
sunlight. Product
loss sensors are available to hold
the signal unless product is fully under view.
Gauge outputs, Operator Interface
& Display
The MCT 360 is available with or without a local operator
interface or display as all the processing is carried out
within the sensor head and the measurement is output via 4-20mA,
0-10V, RS232, RS485 or any bus.
Installation time and effort is minimised by dispensing with
a local OI, but should samples be collected for cross checks
an OI is useful... in this event, one could be simply plugged
into the gauge at the sampling location.
The Measurement
Gauges are delivered pre-calibrated using samples held at
our manufacturing facility, or using customer samples. The
accuracy is application dependent, ranging from +/- 0.1% to
+/- 0.5% . Typically the darker the material appears, the
more NIR absorbing it is, and the lower the signal level…this
means that materials such as crushed coal and coke will require
a longer response time. |
