Product Description
SM35 series wireless load displacement transducer is specially designed for oilfield dynamometer testing.
SM35 transducer integrates the load and vertical acceleration displacement measurement function, low power embedded microcontroller and low power wireless digital communication technology.It realizes Surface Card measurement from the pumping unit, by periodic online synchronous measurement on the Load and Position, and remote transmission through the local wireless communication network.
It's widely applied in oilfields around the world, with high precision, easy installation, convenient maintenance, high reliability, durability, environmental protection and safety function.
