Description
This pressure switch monitors the pressure, displays it and switches two freely settable outputs. The stated material is 1.4301 with wetted parts in 1.4404. The data state a setting range of 0 - 4 bar. This version is supplied with the analogue output 4 - 20 mA and IO-Link version.
Benefits
- Setting range 0 - 4 bar, safe against overpressure up to 8.0 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 and IO-Link for the link into the control system.
Applications
On pumps and compressors the LED display shows the pressure in the range 0 - 4 bar right at the device.
