Description
In use, the pressure switch monitors the pressure, displays it and switches two freely settable outputs. It is produced from 1.4301 with wetted parts in 1.4404. In addition the data give the analogue output 4 - 20 mA version.
Benefits
- Setting range 0 - 160 bar, safe against overpressure up to 320.0 bar.
- Two switching outputs in PNP or NPN, each one freely set as normally open, normally closed, window or hysteresis.
- Switching accuracy 0.5 % of span with a life of 100 million switching cycles.
- Four-digit LED display with 9 mm digits, readable without any extra device.
- Protection IP 67 with a supply voltage of 15 to 35 V (DC).
- Version analogue output 4 - 20 mA for the link into the control system.
Applications
On pumps and compressors the LED display shows the pressure in the range 0 - 160 bar right at the device.
