Review JOHN DEERE Aftermarket Transducer

The John Deere Model AZ57439 Transducer is an essential component of the Quadra-Trac II Selective Catalytic Reduction (SCR) system in select John Deere tractors. This transducer is responsible for accurately measuring the temperature and pressure of the exhaust gases exiting the engine to ensure optimal performance and efficient operation of the SCR system.

The transducer is compact in size, measuring approximately 3.2 inches in length, 1.2 inches in width, and 1.2 inches in height. It is constructed with high-quality materials, designed to withstand the rigors of heavy-duty agricultural use. The housing is made of durable cast aluminum, while the internal components are made of corrosion-resistant materials to ensure longevity.

The transducer utilizes advanced sensor technology to accurately measure exhaust gas temperatures and pressures. The temperature sensor is designed to measure temperatures up to 2000 F (1093 C), while the pressure sensor is capable of measuring pressures up to 150 psi (1034 kPa). The sensor data is then transmitted to the tractor's electronic control module (ECM) for processing and adjustments to the SCR system as needed.

The AZ57439 Transducer is easy to install and connect to the tractor's wiring harness. It comes with a wiring harness and mounting hardware for simple installation. The transducer is also designed to be serviceable in the field, allowing for easy replacement of sensors or other components as needed.

The John Deere Model AZ57439 Transducer is an essential component of the Quadra-Trac II SCR system, ensuring efficient and effective operation of the system. Its compact size, durable construction, and advanced sensor technology make it a reliable and valuable addition to any John Deere tractor.
