More and more construction machinery and equipment are transitioning from traditional mechanical hydraulic systems to electronic hydraulic systems. In order to achieve automatic control, it is necessary to measure the posture of the vehicle body and actuator, and safety is also widely valued. For example, the verticality measurement of the rotary drilling rig mast and the need to adjust the overall posture of the mechanical equipment before the drilling rig starts working, in order to achieve a horizontal state; Angle measurement is required for the lifting angle of the crane boom and the control of the excavation depth of the excavator.
L beam pumping unit
The SIS428 series tilt sensor replaces position sensors for more accurate measurement of absolute displacement. Install the sensor directly on the beam and obtain a linear output with displacement based on the inclination angle of the beam. By combining the measured stroke of the oil well, accurate displacement can be obtained. This lays a solid foundation for pump efficiency calculation and dynamometer measurement.
II. Elevating Platform/Aerial Work Vehicle
For high stroke elevators or lifting equipment, the angle measurement and control of the operating platform are related to the safety of the operator's life. Therefore, it is necessary to measure, control, and alarm the tilting angle of the operating platform and the entire equipment base. The dual axis tilt sensor SIS428 and the omnidirectional tilt switch LIS330 are suitable for this function.
Huilian's single axis and dual axis tilt sensors are both based on improved MEMS technology. The product has analog output and RS485, RS232, CAN digital output, etc., with high accuracy, excellent anti vibration and long-term stability. In the temperature range of -40-85 ° C, the zero drift is less than 0.2 °, the measurement range is from 0 to ± 180 °, the nonlinearity is better than 0.05, and the repeatability is excellent. Due to the advanced anti vibration technology adopted by the sensing unit, the problem of large data changes in the tilt sensor under vibration environment has been solved. The module is insensitive to vibration and can withstand impacts higher than 1000g.
