The PT124G-112/112T/123/123T high precision melt-pressure transducers are ideal for the measurement of melt-pressure in extrusion processes at temperatures up to 350℃. These series are produced with special materials and alloyed elastic diaphragm together with delicate processing and debugging. The main characteristics are high accuracy and small zero and span shifts caused by changes in process temperatures. The model PT124G-112T/123T comes with a temperature sensor, with type J, K, E optional.
