Introduction of Pressure Transducer

PT20 pressure transducerr made by ORR’s own pressure sensor core as sensor sensitive element. Pressure transducer can be transferred liquid or gas pressure into the standard electrical output signal 4~20mA, 0~5VDC, 0~10VDC. P25 pressure transducer is produced by build-in a piezoresistive pressure sensor into stainless steel housing with pressure ports. the product is an electronic device that convert a physical variable (pressure) into an electrical signal(current or voltage) that can be read or acquired by various control, measurement and adjustment devices. PT20 applies laser trimming hybrid compensates transducer zero, span and so on, is widely used for pressure calibration device, auto mobile, plastic and rubber injection presses, presses and metal working machinery, industrial measurement, and HVAC.
