Introduction

The HUB-4xEx is a frequency output, pickup sensor certified for use in explosion
proof areas. The sensor detects the rotation of an approved flow meter’s gears
and emits a frequency signal proportional to the flow. The output signal is a
square wave pulse, which has a duty cycle of approximately 50%. MAG signal
outputs are protected with a self-resetting fuse. This fuse has a 50 mA nominal
trip point. When a trip occurs, turn off power to the sensor and remove output
load to reset the fuse.

Compatible flow meters include:

• JVM-zzz-Ex Models

• JVS-zzz-Ex Models

• JVHS-zzz-Ex Models

• ZHM-zzz-Ex Models

• HPM-zzz-Ex Models

• HM-zzz-AC-Ex Models
