PTL503S digital pressure transmitter

The digital pressure transmitter adopts stainless steel integral components, imported elastic components, high-precision strain gauges, and advanced technology, with high sensitivity, stable performance, and good impact resistance. The joint is made of 17-4 stainless steel and the outer tube is made of 304 stainless steel. The pressure sensor comes with a three and a half LED display and outputs analog signals to sample pressure signals for the backend control mechanism. The structure is compact and compact, with good moisture resistance and excellent media compatibility. Can measure weakly corrosive liquids and gases.

Widely used in industrial equipment, water conservancy, chemical industry, medical, electric power, air conditioning, diamond press machines, metallurgy, vehicle braking, and building water supply urinary catheter pressure measurement and control.
