The melt pressure transducers and transmitters are constructed with a full bridge strain gauge circuit and are made wholly from stainless steel material. Additionally, the pressure diaphragm features a surface treatment with special alloy coating for all models.
The MPT160-series are basic models of melt pressure transducers, with an output of either the strain gauge signal (eg. 3.33mV/V multiplied by the bridge excitation voltage), or the amplified signals (such as 0-10VDC or 4-20 mA). By short circuit, a shunt resistor will be connected which provides the melt pressure transducer with an 80% full scale output signal for calibration without need of the external calibration pressure. The measuring range can be from 0-10 bar to 0-2000 bar, and the measuring accuracy is high, at up to 0.3% fso.
Additional models, based on the MPT160, have extra features for different requirements. The MPT161-series possess an additional function for temperature measurement by means of a built-in thermocouple, which make the MPT161 suitable for measuring both melt pressure and melt temperature simultaneously at a single point
A flexible extension is also available on the two previous models, which provides further thermal isolation to the melt pressure transducer’s electronic circuitry. The MPT26X-series also feature a pressure manometer in addition to the functions of the previous models. The pressure manometer is made 100% from stainless steel, and its display panel is 100mm in diameter with 1.5% accuracy for indicated melt pressure.
Both the rigid stem and flexible extension provide thermal isolation to the melt pressure transducer’s electronic circuitry, which makes it suitable for measurements in plastic, rubber and chemical fibre industries.
