Barriers for Flow Sensors
Inserted into Zone 0 or Zone 20

These barriers are designed to process the inputs from Flow Sensors in Zone 0 or Zone 20 areas and give a switchpoint in the safe area. Thus they may be used also for sensors in Zones 1, 2, 21 and 22
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 0 Insertion for further details.

● ATEX category II (1) G, Ex Zone 0
● ATEX category II (1) D, Ex Zone 20
