High quality service life long hydraulic pressure transducer

Product description

The urea pressure sensor is integrated in the urea pump to monitor the flow pressure of the urea system pipeline, and the pressure signal is fed back to the ECU in real time. The motor speed can be controlled by the signal, so as to realize the stability of the working pressure and the monitoring of the urea injection quantity. Ensuring the urea injection quantity is the key of the whole SCR system. The pressure control of pressure transmitter directly determines the injection amount of urea, and further affects the catalytic reduction effect of urea. After the successful establishment of normal pressure, urea injection pressure stabilized at about 9 kg. Urea pressure transmitter is made of stainless steel shell and high alkali resistant environmental materials; Urea pressure sensor can work in urea solution at -8~85℃ for a long time; The foam sheath inside the sensor absorbs the expanded volume of the urea solution after freezing to protect the pressure sensor. Urea sensor function is to monitor the urea temperature in the urea box, integrated cooling water heating tube, in cold areas for the system heating thawing, can be heated urea solution, prevent urea cold crystallization caused by system failure can not work normally.
