Description
In use, the pressure switch monitors the pressure, displays it and switches two freely settable outputs. The stated figure is a setting range of 0 - 100 bar. In addition the data give the analogue output 4 - 20 mA version.
Benefits
- Setting range 0 - 100 bar, safe against overpressure up to 200.0 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
In process plant the analogue output 4 - 20 mA version reports the pressure to the control system and switches two outputs at the same time.
