TDR00735 Pressure Transducer (X13790348110) | Replaces TDR0025E / TDR0735

TDR00735 is a Trane original factory refrigerant pressure transmitter. It is a high-pressure side LLID device based on the Danfoss AKS 1008 platform, with the engineering number X13790348110. The absolute pressure range is 0–475 PSIA (approximately 32.8 bar), featuring a 7/16-20 UNF fine-thread interface, 24V power supply, IPC3 bus output, and after being connected via KIT19458 (old number KIT12559) wiring harness, it is integrated into the LLID network of CH530. It is installed at the condenser side or the exhaust pressure port of the compressor to monitor the system's high pressure in real time, providing a basis for high-pressure protection and capacity adjustment; if the diaphragm drifts or the signal is interrupted, it will report a sensor failure and lock the machine.
