Embodiment Construction

[0016] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] A calibration bench for pressure transmitter verification, such as Figure 1 to Figure 3 As shown, it includes a table top 1, a base 4 and a lifting frame 7. The upper and lower ends of the lifting frame are installed on the table top and the base, and a buckle 2 is installed on the side of the table top to fix the pressure transmitter. A lifting handle 3 is provided in the middle of the lifting frame to adjust the stretching degree of the lifting frame, and then adjust the height of the table top. There is an installation groove 8 for placing the pressure transmitter to be calibrated in the center of the table, and a nut 5 for installing a standard device (such as an intelligent digital pressure calibrator) and a nut for installing a hand operator are arranged beside the installation groove The card station 6 realizes the reasonable ar...

Abstract

The invention relates to a calibration bench for calibration of a pressure transmitter. The calibration bench is characterized in that the calibration bench comprises a bench surface, a base and a lift frame. The upper end and the lower end of the lift frame are arranged on the bench surface and the base respectively; the middle portion of the lift frame is provided with a lifting handle for adjusting the height of the bench surface; the side surface of the bench surface is equipped with a buckle for fixing a pressure transmitter to be calibrated; the center of the bench surface is provided with an installation groove for placing the pressure transmitter to be calibrated; and the bench surface is also provided with a nut for mounting a standard device and clamping units for a manual operator for instrument adjusting. The calibration bench is reasonable in design, realizes reasonable layout of the pressure transmitter to be calibrated and related instrument and equipment in the calibration process, effectively reduces the influence of external interference factors on pressure transmitter calibration and ensures smooth conduction of the calibration process.

Description

technical field [0001] The invention belongs to the technical field of pressure transmitters, in particular to a calibration platform for pressure transmitter verification. Background technique [0002] A pressure transmitter is an instrument that converts a pressure variable into a transmittable standardized output signal for control and remote transmission. There is a given continuous functional relationship between its output signal and the pressure variable. The pressure transmitter can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal (such as 4mA ~ 20mA), which can be used to supply indicating alarms, recorders, regulators and other instruments for measurement and indication. And process regulation, mainly used for the measurement and control of industrial process pressure parameters, differential pressure transmitters are often used for flow measurement, and are widely used in production prac...
