General Purpose Pressure Switches

Type: PSO

 

Pressure 1...50MPa
Accuracy ±1%FS
Output 1Ch NPN TR, 2Ch NPN TR

 

Description

PSO sensing element has excellent temperature properties by adopting a self temperature compensation foil strain gauge. A diaphragm and a pressure port are composed as one body for the prevention of leakage. It is also durable to an instant over pressure. It can control the system without any controller due to the output of a 1 or 2 channel NPN open collector switch.

 

Features

- Electrical pressure switch with no mechanical moving part
- Fast response 1ms
- Measuring range 0~50MPa
- One or two pressure setting points
- Self temperature compensation foil strain gauge
- Stainless steel media-wetted materials

 

Applications

- Process control
- Hydraulics & Pneumatic
- Compressor Control
- Chillers
- Refrigeration Equipment
