The MODEL 3500 series hydrogen and moisture sensor in transformer oil leverages advanced solid-state Pd alloy technology. The hydrogen and moisture sensor is extremely simple to operate and set up ,which is ideally suited for the immediate and accurate measurement of hydrogen and moisture content within the oil of transformers.

The Pd alloy online monitoring system for dissolved hydrogen(MODEL 3200) offers a cutting-edge solution for the real-time detection of dissolved hydrogen in oil-filled electrical equipment. This advanced system not only provides precise, real-time measurements and trends related to the health status of transformers, but also has exceptional cost-effectiveness.

Functional Features Excellent hydrogen specificity with no cross-sensitivity. Measure hydrogen concentration ranging from ppm level to 100% pure hydrogen. Suitable for installation in narrow spaces, with a packaged chip thickness of less than 0.6 mm. Split-type connection, with customized FPC length. Signal Output: RS485 and 4-20mA.

Functional Features Does not consume hydrogen, oxygen or other carrier gases are not required. Measure hydrogen concentration ranging from ppm level to 100% pure hydrogen. Equipped with pressure compensation function, with a pressure resistance of up to 3.5 MPa. Insensitive to water vapor and resistant to condensed water. Wider applicable range of gas flow rate. Equipped with on-site LCD display. Obtained explosion-proof certification. Equipped with an infrared remote control.

The sensor chip is based on our company's proprietary H2SENSE™ solid-state Pd alloy hydrogen detection technology—a true hydrogen-specific technology that can completely eliminate the problems of inaccurate measurement and false alarms commonly encountered by other hydrogen sensors, which are affected by background gases.
