Digital Pressure Switch

PSR-series is digital pressure switch equipped with a microprocessor as a 700kg/cm2 (approximately

10,000 psi) to be measured and is widely used in industry which is a high-precision measurement of

pressure.

Features:Pressure measured by 316L stainless steel diaphragm. Wheatstone Bridge resistance connected with

silicon strain gages.

When resistance of silicon strain gages is changes proportional to the pressure value is measured.
