The BAPI BA/T1K[0 TO 100F]-RPP-10'-BB2 is a loop-powered temperature transmitter that pairs a 1KΩ platinum RTD (385 curve) probe with an onboard transmitter circuit, factory-calibrated to a 0 to 100°F span and housed in a BAPI-Box 2 (BB2) enclosure. It delivers 4 to 20 ma, 2-wire loop to your controller, so the signal arrives already linearized — no resistance curve to configure at the front end.
The sensing element is a rigid 304 stainless steel probe, 1.75 in long and 0.25 in OD, terminated with 10 ft (3.0 m) of flame-retardant PVC plenum-rated cable. The transmitter linearizes the signal at the device, so the controller input is configured for a standard analog signal rather than a thermistor or RTD resistance curve. BAPI specifies a 12 to 40 VDC supply on a 2-wire loop, and calls for the transmitter to be mounted at least 5 ft from any radio wave-emitting device.

Installation Notes
- Wire with twisted pair, 22 AWG minimum, using sealant-filled connectors. Heavier gauge may be needed on long runs.
- Do not share conduit with NEC Class 1, 2 or 3 AC power wiring, or with feeds to motors, contactors or other highly inductive loads.
- Keep the transmitter at least 5 ft from any radio wave-emitting device — two-way radios within that distance can cause interference.
- Wire with power disconnected. Incorrect supply voltage, polarity or connections can damage the unit and will void the warranty.
- For strap-on pipe mounting, insulate a minimum of four pipe diameters on each side of the probe (a 1/2 in pipe needs 2 in of insulation each way, wrapped fully around).
- The break-off tab on a BAPI Flexible Probe Bracket (BA/FPB) accepts the 1/4 in probe body and limits heat conduction from the mounting surface.
- Mount the enclosure with #8 screws through at least two opposing tabs; a 1/8 in pilot hole makes this easier.
- Use caulk or Teflon tape on conduit entries, and bring conduit in from the bottom for outdoor or wet locations.
