Pressure transmitters for plastic materials
These Pressure transmitters can read pressure of fluid polymers up to 400°C. The transducer incorporates a strain gauge in a four branch Wheatstone bridge circuit of 350 Ohm and an electrical output proportional to the pressure. The end of the transducer consists of a diaphragm made of stainless steel with a coating to resist abrasive materials, slag and residue that are typically bi-products of processing plastic materials.
Models with strain gauge output at 3.3mV/V or amplified 4...20mA, 0...10V are available, the working range is from 350 Bar to 1700 Bar (up to 30000psi) and with accuracy from 0.25, 0.5 and 1% F.S. Operating temperatures depend on the versions and reach up to 530°C.
