Linear - Current and Voltage Sensor - Brand [Weikewei]

linearDegree is a measuresensorThe degree to which the actual characteristics of the measurement system conform to a straight line, as the actual characteristics are usually a curve, there is a deviation between it and the theoretical characteristics, and the magnitude of this deviation reflects the degree of nonlinearity of the actual characteristics. Therefore, the nonlinearity difference can be used to represent the linearity of the measurement system.The appearance requirements should be clear markings, and there should be no cracks, holes, or fractures, as well as other defects that will affect the lifespan, usability, or appearance.

sensorThe calibration of the indication is based on every value within the full range10%The rated signal value is a calibration point, and the indication calibration starts from the lower limit of the measurement range. The load is balanced according to the specified calibration points, and the load is applied to each calibration point,15 sRead latersensorOutput value, up to the upper limit of the measurement range (calibrated stroke). Then, fluctuate the upper limit load upwards by about2%Afterwards, returning to the upper limit value, the output read this time serves as the initial value for the reverse stroke, and is recalibrated in the order of the original calibration points (according to the reverse stroke). A forward and backward stroke is a cycle, and it should be continuous at least3A calibration cycle.

传感器The measurement method is to adjust the signal source so that the output is a square wave signal. The sampling resistor sends the voltage signal to the dual trace oscilloscope channel, and the sensor output signal is sent to the dual trace oscilloscope square channel. Compare the waveform signals of the knife and square channels, and set the comparison point as the maximum signal90%The delay time of the channel signal is the response time. The response time reflects the delay time of the sensor output signal relative to the input signal.

After multiple tests, we have learned that传感器It has characteristics such as insulation resistance, withstand voltage, high temperature storage, high temperature operation, low temperature storage, low temperature operation, temperature shock, steady-state humidity and heat, random vibration, and high temperature life. The storage requirements for sensors must be at a temperature of-10-40 °CAnd the relative humidity is not greater than80%In a dry, ventilated, non corrosive gas and strong magnetic field warehouse. Otherwise, a certain effect cannot be achieved when using sensors.
