What Does Senva Bring to the Table?

Senva has carved out a strong position in the controls market by focusing on what matters most: precise measurement, rugged construction, and easy integration. Their products are engineered in the U.S. and built to perform in commercial, institutional, and industrial settings where there's no room for guesswork.

Here's a look at the core product categories we stock:

  • Senva temperature sensors: From duct and pipe-mount configurations to immersion and outdoor models, these sensors provide the accurate readings your control system needs to maintain optimal conditions.

  • Senva humidity sensors: Critical for applications where moisture levels impact comfort, equipment performance, or product integrity. Senva offers both duct-mount and room-mount options to cover a variety of environments.

  • Senva indoor air sensors: Designed to monitor CO2, VOCs, and other air quality indicators, these units play an important role in maintaining healthy indoor environments and meeting ventilation standards.

  • Senva pressure transmitters: Whether you're monitoring static pressure in ductwork or differential pressure across filters, Senva's transmitters deliver consistent, dependable readings that your BAS can act on.

  • Senva relay modules: Purpose-built for current sensing and equipment status monitoring, these compact modules make it easy to verify fan operation, pump status, and other critical system functions.

Why Contractors and Facility Teams Choose Senva

What sets Senva apart from the crowd is how thoughtfully their products are designed for the people who actually install and maintain them. Wiring is straightforward, mounting options are flexible, and their output compatibility works with virtually every major building automation platform on the market. That means less time troubleshooting on the ladder and more time moving on to the next job.
