S-Series Switch

Why Choose the S-Series Probe?
The S-Series is a specialized platform of air velocity and temperature switches optimized for demanding applications including laboratory, HVAC, high-performance electronics, and more. With both relay and open drain outputs available and configurable alarm behaviors, the S-Series is the most customizable, high-performance airflow switch platform on the market.
Non-Directional Option
Non-directional switches will sense flow from either direction. Non-directional enjoy a performance advantage and are the most popular.
Directional Option
Directional switches only sense flow from one direction, and are immune to flow reversals.
Innovative “Outside the Duct” Installation
Single hole for mounting sensor assembly, without the need for screws or hands inside the duct
Available Outputs
Open Drain or Relay (N.O./N.C. Polarities)
Air Velocity or Temperature Switching
Trip points may be configured for both air velocity and/or air temperature
Universal Voltage Supply
Suitable for applications where an AC or DC supply voltage is encountered
Alarm Behaviors
Configurable Trip Point, Alarm Delay, & Recovery Point
