How to use the axle pin sensor
The axle pin sensor is a cylindrical body made of alloy steel and stainless steel, consisting of a middle part, namely the pressure bearing area, two sensor support areas, and two force measuring areas. The measuring device is a Wheatstone bridge made of strain gauges, installed inside a pin type sensor to prevent external adverse effects such as mechanical damage, dust, moisture, etc. The basic structure output of the pin sensor is voltage signal output, and the output of analog and digital signals is derived from the mv signal. The input form of the force in the middle part of the sensor is shear load, and the support force acting on the left and right parts of the sensor causes changes in the sensor. The deformation caused by shear stress is converted into an electrical signal proportional to the load. Due to the consideration of measurement form, the pin type sensor has an optimal measurement direction. In this optimal direction, the output signal can reach its maximum value. At this point, the pressure direction on the middle part of the sensor is consistent with the main measurement direction, which is indicated by two arrows on the sensor. The actual use of weighing sensors on equipment is also affected by temperature and lateral force. Therefore, our company's products have undergone temperature compensation and signal output compensation during production to ensure that they can achieve the actual accuracy of on-site use. There are two installation directions for sensors: horizontal installation: When installing sensors, a rainproof and anti smashing protective cover (with a depth of 120mm or more and a bottom outlet) should be designed at the aviation socket position, so that the wires can enter the conduit directly after coming out of the protective cover to prevent possible heavy objects from hitting or hanging the wires when threading the steel wire rope. Vertical installation: When installing the sensor, a rainproof and anti smashing protective cover (with a depth of 120mm or more and a side outlet) should be designed above the sensor to allow the wire to enter the conduit directly after coming out of the protective cover. A door shaped protective component (with a height of 130mm) should be designed above the protective cover to avoid damage to the protective cover caused by back and forth friction when the wire rope is loosened.
