How to choose an oil pressure sensor for wheel loader weighing ?
According to the operating characteristics of the loader, the signal acquisition part of the wheel loader weighing is generally composed of weighing sensor, pressure sensor or oil pressure sensor and transmitter. we generally recommend to select the sensor transmitter with the characteristics of anti vibration, anti overload, insulation, anti-interference, etc.
Characters of pressure sensor and transmitter in wheel loader weighing
As a weighing device, there is no doubt that it must be equipped with a weighing sensor . In the application of wheel loader weighing , the function of the weighing sensor is mainly to replace the pin shaft to achieve the weighing function. The pressure sensor is to improve accuracy and weighing safety . And the transmitter is characterized by stable and high weighing accuracy and strong anti-interference ability, which can improve the accuracy of the weighing system.
