Overview
• The BA/#-P-x is a Stainless Steel Replacement probe for use with any BAPI Immersion, or Duct temperature
sensor. They come in a variety of lengths and with TFE insulated plenum cable. The BA/#-P-x sensor is
available in multiple types of thermistor’s or RTD temperature sensors as shown in the specifications. The
probe comes without a box and is made to insert into an existing duct or immersion box fitting as a replacement. It is ideal to replace a damaged probe or to change the length of an existing probe installation.
• The BA/#-HxP is a Humidity Replacement probe w/sintered filter for use with any BAPI Duct or OSA RH
transmitter. They come pre-calibrated and ready to install and use. The BA/#-HxP probe is available with
multiple types of thermistor’s or RTD temperature sensors as shown in the specifications. The replacement
probe comes without a box and is made to thread into an existing duct or OSA enclosure. It is ideal to
replace a damaged probe or worn-out sensor in an existing installation. Replacement 100 micron SS
sintered filters as well as wash down caps are also available. No field calibration is required.
• The BA/#-HxS is a Humidity Sensor Replacement for BAPI room RH transmitters. They come pre-cali-
brated and ready to install and use. No field calibration is required.

section.
•
Fig 6: Typical Humidity Transmitter Probe Replacement
1. Un-install the box and disconnect the wires from the transmitter.
Note color code.
2. Un-screw (CCW) the old 1/2” NPT probe from the back of the box.
3. Screw in (CW) the new 1/2” NPT probe into the back of the box.
4. Install and re-connect the wires per the color code and termination
section.
NOTE: No callibration is needed.
•
Fig 7: Typical Humidity Probe Filter Replacement
1. Un-screw (CCW) the old 1/2” stainless steel filter.
2. Fully screw in (CW) the new 1/2” stainless steel filter.
NOTE: The old filter can be cleaned for future use with
soap & water and then rinse thoroughly.
Specifications subject to change without notice.
