It is ideal for mounting applications inside electronic circuit enclosures or existing thermostats. •The Remote Probe with Plenum-Rated Cable (BA/#-RPP) is a small Stainless Steel temperature sensor used for single point temperature measurement with PVC plenum rated cable. It is ideal for bracket mounting for Chamber, Duct, Thermowell or L-bracket applications. •The Remote Probe with FEP-Jacketed Cable (BA/#-RPFEP) is a small Stainless Steel temperature sensor used for single point temperature measurement with FEP plenum cable. It is ideal for bracket mounting in harsh environments for Chamber, Duct, Thermowell or L-bracket applications. •The Remote Probe with FEP-Jacketed Cable for submersion (BA/#-RPFEP2) is a small Stainless Steel temperature sensor used for single point temperature measurement with submersion FEP plenum cable. It is ideal for bracket mounting in wet or water submersion environments for Chamber, Duct, Immersion or L-bracket applications. All of the above sensors are available in multiple types of thermistors or RTDs as shown in the specifications. The probe is available bare without enclosure or using a termination enclosure in plastic or metal for NEMA1, NEMA 3R and NEMA 4 applications and are all plenum rated.

Example: ½” pipe x 4 = 2”. Insulation should be 2” on each side of the sensor wrapped all the way around the pipe. MOUNTING REMOTE PROBES TO PIPES : Follow the steps below when mounting the remote probe to a pipe. FLEXIBLE PROBE BRACKET : The BAPI Flexible Probe Bracket (BA/FPB) is used to mount averaging sensors. It includes a scored break off for mounting ¼” remote bullet probes.

Larger gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes. Do NOT run this device’s wiring in the same conduit as high or low voltage AC power wiring. BAPI’s tests show that inaccurate signal levels are possible when AC power wiring is present in the same conduit as the sensor wires.
