Why Measure?

An increasing number of applications within the Renewable Energies Market require accurate monitoring and control of the moisture content. The MCT 360 is utilised "on-line" to prevent extruder blockages, ensure product meets specification, maximise productivity and increase the efficiency of the drying operation. The MCT 660 moisture sensor is also widely used in processes involving the lamination of PVB and other moisture sensitive films used in the production of solar cells.

Sensor

Different configurations of the standard cast aluminum MCT 360 are available. Selection is based upon the installation location; If the gauge is to be installed in a potentially explosive atmosphere owiing to the presence of solvents, an ExD enclosure is recommended, a dusty atmosphere would necessitate the use of an ATEX 22-MCT 360, a caustic environment would require the use of a stainless steel enclosure, and a hot environment, vortex cooling or the MCT 330-HD.

Accessories and Options

The MCT 360 may require an internal heat blanket if ambient temperature is likely to drop below 32° F, vortex cooler, sight window, snorkel sampler or sample probe dependent upon the installation location. The MCT 660 can be modified to measure on static samples, one such modification is the removal of the turntable and addition of an angle support bracket.

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. TheMCT 330-HD is always sold with an Operator Interface.

The Measurement

Moisture is the most critical measurement, but other measurements are available and also important. For example; PVB and EVA thickness, this is important due to the fact that moisture level needs to be lower than a critical % and small differences in the film thickness could make all the difference to whether the product lies within specification or not. The moisture measurement is film thickness compensated. Accuracy is application dependent, ranging typically from +/- 0.1% to +/- 0.5% for moisture, obviously accuracy is greater for the PVB application at 0.02%, and worse for variable product such as hog fuel which can be in the region of 1.0%.
