Upgrades made to hazardous area rated flow sensor

May 21, 2019   Don Horne

AW-Lake Company now offers its HUB-40EX Hazardous Area Rated Flow Sensor with a choice of either sinking or sourcing digital output and a choice of 316 stainless steel or aluminum junction box; or for areas with limited space, a version with no junction box at all.

Compatible with any stainless-steel AW-Lake flow meter, the explosion-proof frequency output sensor is ideal for use in any industry or flow measurement application requiring an explosion-proof sensor such as chemical injection, hydraulic fracturing or industrial paint.

Added for equipment with active inputs, the sinking digital I/O provides a ground connection to the load while the sourcing digital I/O version provides an active voltage source for PLCs designed for source output.

The NEMA 4x junction box of the HUB-40EX Hazardous Area Rated Flow Sensor is available in either standard painted aluminum or 316 stainless steel for added protection against corrosion. For a more compact configuration, the sensor is available without a junction box and just wire with flying leads that allows a user to wire their conduit directly to the sensor.

When working with an AW-Lake flow meter or other PD or turbine meter, the HUB-40EX detects the rotation of a meter’s gears and emits a frequency signal proportion to flow. The square wave output signal has a duty cycle of approximately 50 per cent and is protected with a self-resetting fuse. An integral swivel union enables a 360° rotation of the junction box for easy wiring. Units are available in a variety of hazardous area certifications including CSA (US & Canada) or ATEX/IECEx for use in Class 1, Division 1 locations.
