The pressure transmitter calibrator is an important auxiliary device in the pressure meter detection work, and is used together with the pressure standard to complete the pressure transmitter calibration and inspection work.
First, the pressure transmitter calibrator features:
The pressure transmitter calibrator is an important auxiliary device in the pressure meter detection work, and is used together with the pressure standard to complete the pressure transmitter calibration and inspection work.
The pressure pump of the pressure transmitter calibrator uses a high-quality hydraulic pump as the pressure generating component, supplemented by a well-designed fine-tuning, quick-connecting, and stabilizing valve. The utility model has the advantages of simple operation, reasonable structure and good sealing performance, and a wide range of pressure generating system, which can be widely used in industries such as measurement, scientific research, industrial and mining enterprises and instrument manufacturing.
Second, the pressure transmitter calibrator operation:
1. Positive path detection Unscrew the plug on the output 1 and output 2 connectors, open the pressure regulator valve, adjust the fine adjustment to the appropriate position (intermediate position), and close the shutoff valve above the oil cup. Gently operate the lever to bring the transformer oil to the two pressure output ports. Then install the standard meter and the checklist. When the operating lever is raised to about 65 MPa, use the fine adjustment to adjust to 60 MPa. After 2-3 minutes of stabilization, check point by point. (The overpressure protection valve is always open before the pressure is built)
2. Return detection According to the procedure, after the full-scale reading, slowly step down to the verification point with fine adjustment, and check point by point until the zero point. When the fine adjustment cannot be stepped down, you can gently open the shutoff valve to depressurize.
3. Under high pressure, when the pressure drops slowly, close the regulator valve. First use the fine adjustment to fine-tune the pressure to about 65MPa. After 2~3 minutes of voltage regulation, slowly adjust to 60MPa. When the pressure leaks faster, close the regulator valve and close the overpressure protection valve.
