As a precision instrument, the pressure transmitter has many parameters related to it, today we will explain the basic meaning of the main parameters of the pressure transmitter to help users better select and buy. Measurement range: The range of the measured value within the allowable error limit is called the measurement range. Upper Value: The highest value of the measurement range is called the upper limit of the measurement range. Lower Limit Value: The lowest value of the measurement range is called the lower limit value of the measurement range. Range: The algebraic difference between the upper and lower limits of the measurement range is the range. Accuracy: The degree to which the measured measurement is consistent with the true value. Repeatability: The consistency between multiple consecutive measurements of the same measurement under the same measurement conditions. Creep: The change in output over a defined period of time when it is being measured and all its environmental conditions remain constant. Hysteresis: The maximum difference that occurs in the output when the measured value increases or decreases within a defined range. Excitation: The external energy applied to make the pressure transmitter work properly. Generally voltage or current. The output value of the pressure transmitter and other parameters are also different depending on the applied voltage or current, so some parameters, such as zero output, upper limit output, drift and other parameters, should be measured under the specified excitation conditions. Zero drift: Zero drift refers to the change of the output value of the zero point at a specified time interval and under standard conditions. The zero drift due to the change in the ambient temperature is known as the thermal zero drift. Overload: Usually the maximum value that can be measured when applied to a pressure transmitter without causing a permanent change in performance. Stability: The ability of a pressure transmitter to be stored, tested or used under specified conditions, and to maintain the original characteristic parameters after a specified period of time. Reliability: refers to the ability of the pressure transmitter to complete the required function under specified conditions and within a specified time. Operating temperature: refers to the ambient temperature range within which the pressure transmitter can achieve various technical indicators and functions. Ambient temperature: refers to the temperature range of the working environment in which the pressure transmitter is in working condition.
