Load sensor

The WLL series load sensor is a special power curve acquisition device for oil well load measurement, integrating data acquisition, data processing, wireless transmission, information storage, automatic detection, and fault diagnosis. It features a low-power design and can be powered by lithium batteries or solar charging. Using high-precision A/D acquisition and signal conditioning, it achieves high measurement accuracy. Digital information processing and filtering technology enable automatic measurement of stroke and stroke count data, with simultaneous data upload. It has a proactive fault alarm and upload function, and timely reminds users to replace the battery when the battery power is low.
