Embodiment Construction
[0026] The present invention is described in further detail below in conjunction with accompanying drawing:
[0027] A method for manually clearing an intelligent digital display pressure transmitter includes the following steps:
[0028] During the use of the transmitter, when the error is a fixed constant value within the entire range of the transmitter, it is judged that the error caused by time drift only affects the zero point and sensitivity, and the transmission can be completed by using the manual zeroing process The secondary calibration of the transmitter; when the error is a monotonically increasing or decreasing value within the entire transmitter range, the error caused by the positioning time drift affects the linearity, and the secondary calibration process of the transmitter can be used to complete the secondary calibration calibration
[0029] Manual clearing includes the following steps:
[0030] 1. First, collect the analog input of the pressure, calculate...

The invention discloses a method for manually clearing an intelligent digital display pressure transmitter. During the use of the transmitter, when the error within the range of the entire transmitter is a fixed constant value, it is judged to be caused by time drift If the error only affects the zero point and sensitivity, use the manual zeroing process to complete the secondary calibration of the transmitter; when the error is a monotonically increasing or decreasing value within the entire range of the transmitter, the error caused by the positioning time drift affects the Linearity, the transmitter can be recalibrated using the recalibration procedure. The whole clearing process of the product of the present invention is simple in design and convenient in operation, which saves the labor cost of customers and manufacturers; at the same time, due to its own digital display function, the efficiency of on-site operation is greatly improved, and the cost of enterprise personnel is saved.
Description
technical field [0001] The invention belongs to the technical field of automatic detection and control, and relates to a method for manually clearing an intelligent digital display pressure transmitter. Background technique [0002] The sensor converts non-electrical physical quantities such as temperature, pressure, liquid level, material, gas characteristics, etc. into electrical signals or sends physical quantities such as pressure, liquid level, etc. directly to the transmitter, usually consisting of conversion elements and sensitive elements. The transmitter amplifies the weak electrical signal collected by the sensor to transmit or activate the control element. Or a signal source that converts the non-electricity input from the sensor into an electrical signal and amplifies it at the same time for remote measurement and control. According to the definition of "Encyclopedia of China", a transmitter is a sensor whose output is a standard signal. Sensors and transmitter...
