Combination units reduce fluid system costs and assembly requirements. Most standard and custom SMD liquid level sensors can be assembled with a thermocouple, RTD, or thermostat switch, meaning that almost all of our float switches can be customized for multiple applications.
FM22 – Liquid Level and Temperature Switch
The FM22 Level and Temperature Sensor is bi-metal, snap-action and can be used to provide temperature protection in most fluid systems. Thermostat switches are designed to be normally open (NO) or normally closed (NC) and will change state at a specified temperature. These slightly larger devices require full-size stems and an additional inch at the bottom of the stem. Thermocouples are ideal for interfacing with existing meters or for where higher temperatures may exist. Ceramic filters can be used in place of standard potting to provide level and temperature sensing to 200º C.
