No construction required for install

The complete kit can be installed in minutes and requires no wiring or wall modifications; all you need is just a ladder and screw driver. First, remove the existing sensor covers and replace them with Setra’s sensor. Next, connect using existing wires. Then, remove the legacy monitor and replace with Setra FLEX. Connect using existing wires and power, configure FLEX and you’re done!

Low-maintenance & contaminant-free sensing technology

Setra’s pressure transducers are dead-ended sensors, which means there is no air flowing through pressure tubing. Our proprietary variable capacitance transducer requires no maintenance or cleaning. Re-zero can be done on the Setra FLEX touch screen and sensor calibration can be performed if the application requires it.

The Setra FLEX unit includes a brilliant 7” touch screen display, configurable visual and audible alarming, isolation and non-isolation modes, alarm delay, key switch input, and control operation for VAV dampers. Multiple units can be easily configured using Setra’s USB cloning feature.
