Have you been looking for an APCO TL008 combination float switch and temperature sensor? If so, you are not alone!

Unfortunately, APCO TL008 sensors can be difficult to find. The unit is largely listed as out of stock or unavailable online. This can be frustrating!

Luckily, SMD Fluid Controls offers a similar combination level/temperature sensor with their FM22 line of sensors.

Features of the FM22 Line of Temperature Level Sensors


FM22 combo level/temperature switches are bimetal, snap-action switches that can be used to provide temperature protection in most fluid systems.

These switches are available in either normally opened or normally closed configurations, and will change state at a specified temperature. In addition, resistive Temperature Detectors, or RTDs, provide accuracy and linearity at a low cost.

Other features include:

  • Switch Type: 50 W
  • Max Switching Current: 0.5 A
  • Max Switching Voltage: 200 VDC
  • Maximum Temperature: 120° C
  • Maximum Pressure: 125 PSIG
  • Specific Gravity: 0.5
