One of the product that comes from the categories of Flow Sensor& Pickups is DH-X Dual Hall Effect Sensor.

DH-X Dual Hall Effect Sensor

The DH Dual Hall Effect Pickups are microprocessor-based sensors for use with the JV-CG and JV-KG series of positive displacement flow meters. The DH sensors can detect both uni- and bi-directional flow. The sensors’ mode of operation is determined by an output selection switch located inside the housing. The DH 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%.

DH 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 sensor has two different output configurations: sinking output and sourcing output.The DH sensor circuit board is equipped with a red and green LED. The red LED is a status LED which, when the sensor is operating properly, will flash once every 2 seconds. The green LED indicates the pulse of the input signal. Note that signals above 20Hz will look as solid green.

Features:

• Meter Compatibility: Used with JV-CG and JV-KG up to -60 size (excluding JVM-01CG)
• Flexible: Detects both uni- and bi-directional flow
• Output Signal: Square wave pulse with duty cycle of approximately 50%
• Protection: DH signal outputs protected with a 50mA nominal trip point self-resetting fuse
• Two Output Configurations: Sinking output and sourcing output
• Output Options: Choose from 2X pulse resolution in a signal pulse train (default) or a quadrature signal with a 90° phase shift
