Description

The crosshead-mounted EMS121 load sensor measures polished rod load and transmits the data to the rod pump controller for monitoring and control purposes. The sensor is engineered for reliable performance in demanding oilfield environments, including desert regions,Arctic conditions, and environments with aggressive chemicals and explosive gases.
‍
High measurement accuracy is achieved through precision manufacturing, temperature compensation of the strain gauge bridge, and individual testing of each sensor during production.
‍
The standardized housing allows the EMS121 to be easily installed as a replacement for load sensors from othermanufacturers. The sensoris connected to the controller using a specializedhigh-flexibility cable, ensuring stable signal transmission and reliable operation in field conditions.
