Overview
The BA/T#-D is a duct mounted 4 to 20mA or Voltage temperature transmitter probe. It comes in a variety of probe
lengths and optional mounting enclosures shown below. The 4 to 20mA transmitter can be ordered with 100Ω (385), 1KΩ
(385) RTDs or 10KΩ type 2 thermistor sensors. A 0 to 5VDC or 0 to 10VDC transmitter is also available with the 10KΩ
type 2 thermistor sensor. Special high accuracy RTD matched transmitters (M) are available which match the sensor to
the transmitter for improved accuracy.

Mounting
1. Place the sensor in the middle of the duct
away from temperature stratied air, coils
or humidiers to achieve the best temperature reading.
2. Drill the probe hole as depicted on this
page for the enclosure being used. Insert
the probe into the duct.
3. Mount the enclosure to the duct using
BAPI recommended #8 screws through a
minimum of two opposing mounting tabs
provided. Weatherproof (WP) enclosures
require assembly of the mounting tabs on
opposite corners. A 1/8 inch pilot screw
hole in the duct makes mounting easier
through the mounting tabs. Use the enclosure tabs to mark the pilot hole locations.
4. Snug up the sensors so that the foam
backing is depressed to prevent air leakage but do not over-tighten or strip the
screw threads.
Note 1: Do not drill into the weatherproof
enclosures (BB, BB2, WP, EU, EUO) which
will violate the NEMA and/or the IP rating.
Note 2: Use caulk or Teon tape for your
conduit entries to maintain the appropriate
NEMA or IP rating for your application.
Note 3: Conduit entry for outdoor or wet applications should be from the bottom of the
enclosure.
