Hello everyone, welcome to the Star Instrument Classroom, in this issue, let’s talk about several important indicators that affect the accuracy of pressure transmitters? The main indicators that affect accuracy are: zero output, full-scale output, hysteresis, and repeatability. Zero Output: The output value of the sensor is zero when it is measured to zero Full-scale output: The absolute value of the difference between the upper output value of the sensor measurement and the lower output value of the measurement limit is the full-scale output value Hysteresis: Within the specified range, at the same test point, the hysteresis of the sensor is described by the absolute value of the difference between the increase and decrease of the output of the measured value as the hysteresis of the measurement point, and the hysteresis of the sensor is described with the largest hysteresis of all measurement points. Repeatability: Repeatability is the consistency between multiple consecutive measurements of the same measurement under all the following conditions (same measurement method, same measuring instrument, same location, same conditions of use, and repetition over a short period of time). These four errors are unavoidable, we can only choose high-precision production equipment, use the latest technology to reduce these errors, and can also carry out certain error calibration at the time of delivery, as much as possible to reduce the error to meet the needs of customers.
