Product Overview

The SZ901SZ902 integrated wireless power diagram sensor is a continuous measurement of the tension and displacement data of the sucker rod within one cycle of the pumping unit, and ultimately forms a closed graph. Use this graphic to reflect the condition of the oil well. It is installed on the light pole, and the measured power diagram data is uploaded to the wireless gateway through a 2.4G network.

● Split type wireless power diagram sensor. The SZ907 wireless angular displacement sensor is used to measure the angle changes of the pumping unit (pump), and is usually used in conjunction with a wireless load sensor to measure the power diagram of low impulse oil wells and coalbed methane wells. The SZ908 wireless load sensor is used to measure changes in the load of the pumping unit (pump) and is used in conjunction with the SZ907 to form a success chart. Usually used for coalbed methane wells or oil wells with low impulse and small stroke.

The SZ903/SZ903D wireless pressure gauge and SZ905/SZ905D wireless temperature gauge are new sensors that integrate high-precision signal measurement, wireless RF, and routing networking technology. It can measure pressure signals of various media and transmit the signals to the wireless gateway module through a 2.4G network. It has the characteristics of no wiring, long working time, and investment savings.

The SZ904 wireless torque sensor is used to measure parameters such as torque, load, and speed of rotating devices (such as screw pump pumping unit well rotating light rod), and the collected signals are converted into digital signals for communication through 2.4G wireless network and wireless gateway.
