Control unit FS870
For standard use in ATEX and IECEx zones 1 and 21
- Flow measurement without orifice plate, therefore no increased back pressure
- Flow measurement with a large dynamic range of 1:50 compared to orifice measurement with only 1:5
- Simultaneous PID control of housing pressure and flow rate possible, values programmable
- Purging phase with the same low pressure level as the operating phase despite high flow rates
- Ethernet interface for connection to the management/control level
- No external pressure and flow monitor required
- Readable diagnostic memory
