Automated logic's Immersion Temperature Sensors are available in 2”, 4”, and 8” probe lengths. The sensor is potted inside a 1/4” stainless steel probe with thermally conductive epoxy. All Immersion Units have etched Teflon leadwires and double encapsulated sensors to create a watertight package that can withstand high humidity and condensation.

Immersion Units come standard with a 2”x4” steel J-Box or a nylon and ABS plastic BAPI-Box 4 enclosure. They are also available with a watertight BAPI-Box or BAPI-Box 2 enclosure.


  • 2", 4” & 8” Probe Lengths: (fit our standard Thermowells)

  • Series 304 SS Probes & Double Encapsulated Sensors

  • Optional BAPI-Box or BAPI-Box 2 Enclosure


Probes are designed to be inserted into a Thermowell. Thermowells are available in lengths to match our Immersion Probe Lengths.
