Rigid Averaging Duct Temperature Sensors (BA/# -RA)

20904_ins_DuctAvgRigid_Passive_Passive

Overview and Identication

The Rigid Averaging Unit is for duct mounting and
temperature measurement of stratied air across the duct
to give the average temperature along the length of the
sensor.

The rigid Stainless Steel Probe is made in different
lengths for a custom duct t. The units is available
in multiple thermistor or RTD types as shown in the
specications. Enclosure mounting styles come in plastic
or metal for both NEMA 1 and NEMA 4 applications and

are all plenum rated.

Installation & Operations

Mounting

1. Place the sensor in the middle of the duct away from temperature stratied air, coils or humidiers to achieve the best
temperature reading.

2. Drill the probe hole as depicted below for the enclosure being used. Insert the probe into the duct.

3. Mount the enclosure to the duct using BAPI recommeded #8 screws through a minimum of two opposing mounting

tabs provided. Weatherproof (WP) enclosures will 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.
