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.

Choose a reliable manufacturer

Changsha Taihe Electronic Equipment Co., Ltd. was founded in the 1980s as a state-owned enterprise (the former electronic equipment factory of Central South University) , With 2000 square meters of workshops and perfect quality system certification . It is a famouse local high-tech enterprise . And the product PPM-S322A has a market share of more than 80% in China .

 The application of load cell in the transfer machine is naturally not less. In the wheel loader weighing , the function of load cell is mainly to replace the pin shaft to achieve the function of weighing. The function of the pressure sensor is mainly to improve the accuracy and the weighing safety performance. The transmitter is to stabilize the weighing accuracy and has strong anti-interference ability to improve the accuracy of the weighing system. Now we are cooperating with excellent loader manufacturers in the world , working on Oil pressure sensor with small volume, high precision and high performance . It has a wide field application foundation and supports customized research and development.
