This document introduces the features and characteristics of the PS83 series pressure switches, including no mechanical moving parts, high corrosion resistance, double diaphragm structure, two pressure setting points, wide pressure medium compatibility, and the ability to connect with VCR® fittings.
The PS83 series is a solid‑state pressure switch featuring a double‑diaphragm construction for high corrosion resistance. It offers multiple pressure reference options (gauge, vacuum, absolute) and can be fitted with G‑type, R‑type, or VCR® connections.
Key specifications include a rated pressure range from 0 to 34.3 kPa (up to 981 kPa for higher‑range models), supply voltage of 12‑24 VDC, NPN open‑collector outputs, and an operating temperature range of –20 °C to 70 °C. The device is built with SUS 316L fittings, an aluminum housing, and includes LED indicators for output status.

The PS83 series offers rated pressure ranges such as 0 ~ 34.3 kPa, 0 ~ 49.0 kPa, 0 ~ 98.1 kPa, and up to 0 ~ 981 kPa depending on the model.
It provides an NPN open‑collector output.
The device operates from a 12 V to 24 V DC supply (±10%).
Each PS83 unit has two outputs.
