Trane TDR0744 Low Pressure Transducer, 2-10VDC/0-20" WC

The Trane TDR0744 Low-Pressure Transducer is a small, low-profile device used to monitor and translate low air pressure changes into electrical signals for HVAC systems, clean rooms, and other industries. It produces an equivalent voltage that is proportional to the pressure of air acting upon its internal diaphragm. Normally, this voltage output is in the range of 2V to 10V DC; higher voltage levels indicate higher levels of air pressure. Because this has a light construction and is relatively easy to install (it has a 3/16” OD compression fitting and 1/4” tubing), it is a useful option for a range of HVAC equipment.
