Barriers for Flow Sensors
Inserted into Zone 1 and Zone 21


These barriers are designed to process the inputs from Flow Sensors in Zone 1 or Zone 21 areas and give a switchpoint in the safe area. They accept the 4-wire single channel input and display flow rate using a chain of 6 LEDs.
The setpoint is selected using a potentiometer. Output is by changeover contact.
See Flow Sensors for Zone 1 Insertion for further details.


● ATEX category II (2) G, Ex Zone 1
● ATEX category II (2) D, Ex Zone 21
