The GMP series of melt pressure sensors (transmitters) are designed for pressure monitoring of liquids, gases or pastes at high temperatures, they must be in a liquid, gaseous or viscous state with a pressure not exceeding the upper limit of the measuring range under normal use and 150% of the upper limit of the measuring range for instantaneous pressure (based on the diaphragm surface). The use of high-performance core components, more anti-interference analog circuit design, and calibration linearity at high temperatures of 200C can obtain high measurement accuracy, and only if properly handled, their service life will be longer.
