Description
1. Summary
SM36 series wireless angular displacement transducer is designed for beam pumping well position feedback and angle detection. It integrates micro-power ZigBee communication, inclination sensor, low-power single-chip microcomputer and other technologies. It is one of the important front-end acquisition equipment for the construction of digital oilfield oil and gas IoT production. It realizes dyno-card remote measurement, through measurement the inclination angle of the beam pumping unit periodically and online synchronously with the SM34/35 series wireless load sensor and transmits remotely through the local wireless data communication network.
