Sensor

The new MCT 460-WP and it`s forerunner, the MCT 300-WP are dedicated wood product gauges, they incorporate an integrated cooling panel, an air purge diffuser and utilize a well proven algorithm which works on a wide range of wood varieties and forms.

The MCT 360-WP can measure moisture within a wide range of products but will require different calibrations if the gauge is to be moved to a different location.

If owing to potentially hazardous dust accumulation, a zone 22 gauge is required, PSC offers the ATEX 22-MCT 360.

The MCT 230-BT is a low cost benchtop gauge that has been recently added to Process Sensors NIR range. It provides instantaneous moisture readings for wood chips or finer wood particles, and eliminates the bias in moisture readings induced by the small unrepresentative samples typically presented to a moisture balance.

Accessories

Depending upon the installation location, one or more of the following may be necessary; a vortex cooler, heat blanket, product loss sensors, sight glass and sample probe.

Gauge Outputs, Operator Interface & Display

The MCT 360-WP 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

In addition to moisture, resin content can also be monitored as a "Trend Measurement", essentially the gauge will respond to an increasing or decreasing percentage but owing to the difficultly of performing an accurate calibration the gauge value cannot be taken to be the actual percentage.

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% .
