Melt Pressure Transducer Simulator

The Terwin pressure transducer simulator has been designed as a service aid to engineers that are involved in the extrusion of plastics, rubber and food.

Should a fault occur on an extrusion pressure monitoring / control system, the simulator will enable the plant engineer to check the cable assembly and associated indicator / controller / signal conditioner by simply plugging the transducer cable assembly into the simulator and checking all the functions with the eleven point rotary switch.

Terwin T1500 Comparison Test Pump

The Terwin model T1500 comparison test pump is a hydraulic comparison test pump for generating pressure up to 1,200 bar. The integrated dual-area spindle pump with switching valves enables rapid filling of the test system and smooth pressure generation. At the same time, the precisely adjustable spindle pump also serves
for pressure fine adjustment. A control schematic for pressure generation on the instrument base facilitates quick and easy operation.
