Load sensor/PDM-800ZD

★ Measurement of dynamometer diagram: It can be used as a combination of a single load sensor and an angular displacement sensor to measure the load value of the rod during each stroke of the oil well at regular intervals, and then obtain the dynamometer diagram of the oil well; It can be combined with a wire displacement sensor and a dead point switch sensor to measure the load value and stroke value of the rod during one stroke of the oil well in a pre calibrated mode, and then obtain the indicator diagram of the oil well; It can work in the power diagram acquisition mode of single dead point or double dead point, and measure the load value of the oil well during one stroke at regular intervals to obtain the oil well power diagram;
★ Real time measurement: Supports wireless wake-up function. During normal operation, this sensor is in a low-power sleep state, and can be instantly awakened through the wireless interface to perform functions
★ Measurement instructions can be used to achieve real-time monitoring of power diagrams, and real-time collection and measurement of power diagrams can also be carried out based on remote wake-up commands from RTU units;
★ Battery level detection: Actively upload battery level, with battery level detection function;
★ Wireless calibration;
★ Wireless communication interface: 1-channel Zigbee communication;
★ Power supply method: Provide internal battery power supply;
★ Support the collection of indicator diagrams for variable speed operation mode (i.e. double dead center mode) of oil wells.
