Hall Effect Sensor HEF Series AW Lake

AW Lake is a corporate from the United States of America that sells some products such as Positive Displacement Meters, Turbine Flow Meters, Tricor Coriolis Flow Meters, Lake Variable Area Flow Meters, Lake Paddle Wheel Flow Meter "Flow Stat", Monitor&Controllers, Flow Sensor & Pickup. One of the products that come from the categories of Flow Sensor & Pickup is Hall Effect Sensor HEF Series.

Hall Effect Sensor HEF Series :

The HEF is a Hall Effect sensor that is compatible with the Aluminum, 303 Stainless Steel, and 316 Stainless Steel body JV-CG and JV-KG series of flow meters. 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%.

HEF signal outputs are protected with a self-resetting fuse. This fuse has a 50mA nominal trip point. When a trip occurs, turn off the power to the sensor and remove the output load to reset the fuse. The HEF sensor has two different output configurations: HEF-A or HEF-AA for a sinking output and HEF-B or HEF-BB for sourcing output.

Installation :

• Ensure that the flowmeter sensor cavity is free of debris prior to installing the pickup.
• Make sure the sensor mounting screws line up with the mounting holes. If they do not, remove and rotate the sensor 180°
