Electronic Pressure Switch : PSL

Sensor System | Pressure Sensor / Switches | View PDF

The PSL model, the sensing element, has excellent temperature properties by adoRing a self temperature compensation Glass on Titanium. Since it does not use O-ring, there is no possibility of corrosion and leak. It can control the system without any controller due to the output of a 1 or 2 channel NPN open collector switch.

Feature
Electronic pressure switch with
no mechanical moving part
Fast response 1ms
Measuring range 0~150MPa
One or two pressure setting points
Piezoresistive silicon cell
Stainless steel, Titanium Diaphragm

Applications
Process control
Hydraulics & Pneumatic
Compressor Control
Chillers
Refrigeration Equipment
