Description:
The MAG-J is a Hall Effect sensor which is compatible with all AW and KEM Positive Displacement gear flow
meters except ZHM-04 to the ZHM-07KL. The sensor detects the rotation of the flow meter’s gears and emits
a frequency signal proportional to flow. The output signal is a square wave pulse which has a duty cycle of
approximately 50%.
MAG-J signal outputs are protected with a self-resetting fuse. This fuse has a 50mA nominal trip point. When
a trip occurs, turn off power to the sensor and remove output load to reset fuse.
The MAG-J sensor has two different output configurations: MAG-J-PA for a sinking output and MAG-J-PB for a
sourcing output.
Installation:
• Ensure that the flowmeter sensor cavity is free of debris prior to installing pickup
• Swivel fitting is required for sensor mounting
• 4 Steps to properly install sensor:
1- Securely fasten swivel fitting on flow meter
2- Turn set screws counter clockwise until they are not visible inside the swivel fitting
3- Install sensor into swivel fitting until sensor bottoms out in the sensor hole
4- Tighten set screws by turning clockwise
NOTE: DO NOT OVER TIGHTEN SET SCREWS OR SENSOR DAMAGE WILL OCCUR!
NOTE: WIRING SHOULD BE INSTALLED BY A QUALIFIED INSTRUMENTATION TECHNICIAN
