20921_ins_RemoteSen_Active

Overview

• The BA/#-PP is a small temperature conductive plastic sensor used for single point temperature measurement with twin plenum
rated lead wires. It is ideal for mounting applications inside electronic circuit enclosures or existing thermostats.

• The BA/#-RPP is a small Stainless Steel (SS) 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 BA/#-RPFEP is a small Stainless Steel (SS) 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 BA/#-RPFEP2 is a small Stainless Steel (SS) 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.

The BA/#-(PP, RPP, RPFEP, RPFEP2) units are available in multiple types of 4 to 20mA transmitters that 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. Enclosure mounting styles come in plastic or metal for both NEMA 3R and NEMA 4
applications and are all plenum rated.

Step 1: Secure Sensor To Have Good Contact With Bare Pipe

Step 2: Insulate Over The Sensor (See Notes Below)

Notes: Insulation should be installed a minimum of 4 pipe

diameters on each side of the strap-on sensor.

Example: ½” pipe x 4 = 2”.
Insulation should be 2” on each side of the sensor wrapped all

the way around the pipe.

Wiring & Termination

BAPI recommends using twisted pair of at least 22AWG and sealant lled connectors for all wire connections. 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.

Diagnostics

Possible Problems: Possible Solutions:

• Unit will not operate. - Measure the power supply voltage by placing a voltmeter across the transmitter’s (+) and

- Check if the RTD wires are physically open or shorted together and are terminated to the

- Measure the physical temperature at the temperature sensor’s location using an accurate

• The reading is incorrect in the controller. - Determine if the input is set up correctly in the controllers and BAS software.

- For a 4-20mA current transmitter measure the transmitter current by placing an ammeter

T = Temperature at sensor
TLow = Low temperature of span
