Melting pressure transducer for extruders
max. 2 000 bar | MPT series
BCM SENSOR TECHNOLOGIES bvba
BCM melt pressure transducers and transmitters (MPT) are developed from BCM strain gauge
technology and manufactured in mass production. The MPT are constructed with a full bridge
strain gauge circuit and 100% made from stainless steel material (standard version).
In addition, the pressure diaphragm features a surface treatment with special alloy coating for
all the MPT models. Both the rigid stem and flexible extension provide therma isolation to MPTs
electronic circuitry, which enable MPT suitable for melt pressure and melt temperature
measurements.
The output of BCM MPT is either the strain gauge signal (for instance, 3.33mV/V multiplied by
the bridge excitation voltage), or the amplified signals (such as 0~10 Vdc or 4~20 mA). By
short-circuit, a shunt resistor will be connected which provides MPT with a 80%fso signal for
calibration without need of the external calibration pressure.
Features:
flexible extension providing further thermal isolation to electronics
amplified outpout signal available in 4~20 mA or 0~5, 0~10 Vdc
wide measuring range of 0/10 bar to 0/2000 bar
availability for zero and span adjustment
internal shunt calibration signal of 80%FS
