Hello!
refer my below query regarding requirement of barriers in safe area.
Suppose Compressor system will be kept in hazardous area (gas group IIA/IIB) & relay based starter cum control panel will be in safe area. Pressure sensors, temp sensors & solenoids will be mounted on compressor system.
Do I need to use safe area barriers for the pressure & temp.sensors (4-20mA) at panel incoming? reason? & whether these are also required for solenoid valves (24 v dc) reason?
please guide me.
Thanks in advance.
regards,
Shailesh
