Product Description

 Description :
The SMDW35B-2 wired load sensor is a load sensor with high anti-interference performance. The product adopts standard voltage of 0.1-1.5V signal output and fully sealed design, can work in high temperature, high cold, high humidity, high radiation and other harsh environment, currently widely used in pumping unit power diagram measurement system.

The high reliability design adapted to the industrial environment, as well as the characteristics of high precision, simple installation, convenient maintenance, environmental protection and durability have won the recognition of users, not only in domestic Shengli, Daqing, North China, Changqing, Xinjiang, Qinghai and other major oil fields have been promoted and applied, but also in overseas oil companies.

Characteristics:
1. Continuous improvement after 20 years of use in various oilfields across the country;
2, fully sealed waterproof design, meet the all-weather use;
3. Optimize wiring terminals to improve reliability;
4, easy to operate and safe;
5, standard 0.1 ~ 1.5V three-wire output;
