Description
The Trane TDR0731 is an essential element of Trane HVAC systems, which is aimed to control low air pressure. This compact transducer, measures the air pressure within the system and produces a proportional electrical signal. It has a 1/5” barbed fitting to connect directly to conventional 1/4” tubing for pressure reading. The TDR0731 measures changes in air pressure from 0-20 inches of water column and produces a voltage output of 2-10 volts DC. This electrical signal is then relayed to the main control board where the Trane system understands the signal and adjusts some of the other functions as well.
