LOAD CELL EMS121 is designed to measure load on polished rod and is intended to work with rod pump controller. EMS 121 construction allows it to reliably work in harsh oil industry conditions, including far north and desert environment with presence of aggressive substances and explosive gases.
High accuracy is provided by precise manufacturing and temperature-compensated bridge of strain gauges, as well as by individual testing of each sensor after manufacturing.
Standard design allows to install EMS121 instead of load cells of other manufacturers.
