Thermobuffer Temperature Transmitters
BA/T#- TB Temperature Transmitter
Installation and Operation Instructions
20898_ins_Thermobuffer_Active
Overview
The BA/T#-TB is for measuring the temperature in walk-in-freezers or refrigerators with a wall or hanging bracket sensor.
The buffers are made in different lengths and are made to be lled with food grade glycol to slow down the temperature
response to more closely simulate the contents of the freezer or refrigerator.
The BA/T#-TB transmitter is available in
common temperature ranges and 2-wire, 4-20mA or voltage signaling as shown in the specications. The mounting enclosure styles come in NEMA 4 plastic or hanging bracket with the buffers available in stainless steel or aluminum to t any
application.

1 Fill the buffer with the appropriate amount of customer provided glycol
to the amount as dictated by table 1.
2 Wrap the probe threads with Teon tape with at least 4 wraps so a water
tight seal is established.
3 Insert the probe into the buffer and screw in for a secure water tight t.
4 Towel off excess uid which may leak out during assembly and check
for leaking. If the assembly leaks, a 15/16ths wrench may be used to
snug up the probe to the buffer. More tape may also be needed. The
use of food safe silicon may also be used.
5 Select a location on a wall or hanging from a wire rack near the contents
you wish to monitor.
6 Mount the Thermo Buffer with the buffer facing down (Probe on top).
Any other orientation is not recommended due to leaking concerns.
7 We recommend BAPI Box surface mounting be positioned over the
refrigerator wire way hole using the rear BAPI Box knock out. Pull the
wiring into the unit and terminate using sealant lled connectors. Best
practice is to caulk the wiring hole after the wiring is installed. Secure
with mounting screws and ensure that the foam backing compresses
to about 50% of its thickness to make a gasket type seal against the
surface.
