AW-Lake upgrades hazardous area rated flow sensor
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 or hydraulic fracturing.
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% 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.

Industries such as construction, mining, energy, utilities and forestry, face many challenges when it comes to tracking assets and employees. Equipment often has to be transferred between locations, or monitored while it is dormant during off seasons. Lone workers may have to travel long distances or visit multiple sites during the course of their activities. And, all of this is further complicated today with shifting supply chains and economic realities putting further strain on the bottom line.
