TFP-T Series Liquid Leak Sensor

Minimize damage to your devices and components with a chemical-resistant liquid leak detector sensor. These highly reliable liquid leak sensors use infrared light to detect liquid or water leaks, regardless of the reflectivity or viscosity of the liquid. Our TFP Series leak detector sensor is constructed with a Teflon (PFA) casing and cable (FEP), ensuring resistance to harsh chemicals.

Note: These components are not intended for use with flammable liquids or in explosive environments.


UL FIle number: E202019
