FPS-T Series (HVAC/R) Liquid Level Sensor
The FPS-T Series is a tube-mounted flood prevention switch designed for HVAC/R systems, offering reliable protection against condensate overflow. Engineered for vertical installation, it automatically shuts off air conditioning systems when water levels rise due to clogged drain lines—helping prevent damage to ceilings, walls, and floors.
Its tube-mount design allows for easy installation directly into the drain line, making it ideal for both new construction and retrofit applications. The FPS-T Series complies with UL508, NEC, and IMC standards, ensuring dependable performance and code compliance in residential and commercial HVAC systems.
