Portable automatic pressure calibration table Introduction
CWY automatic pressure calibration table includes pressure generation, pressure measurement, electrical signal measurement and HART communication function. It is suitable for testing pressure transmitter, pressure switch (pressure controller), pressure indicator and so on.
CWY series portable automatic pressure calibration table can be built-in HART function, replace HART handheld device, set or calibrate HART transmitter range, force HART transmitter output current to a fixed value (such as 20mA, 12mA, 4mA) , set the linear or square function, you can HART zero the pressure sensor of the transmitter. It is more convenient to use than the HART Communicator.
CWY automatic checker built-in pressure source; built-in rechargeable lithium battery; built-in pressure module; built-in HART function; light weight, easy to carry; AC and DC; automatically save the verification results, the verification results can be exported from the U disk. features
1. It can automatically check pressure transmitter, pressure switch and pressure indicator.
2, pressure transmitter verification
3. Pressure switch verification: It can automatically detect the action value and reset value of the pressure switch, and can detect the contact resistance of the pressure switch.
4. Safety protection: protection against overvoltage and overvoltage sensor failure.
5, loop power: DC24V / 30mA, if you accidentally access the standard table, will not damage the standard table.
6, pressure interface: M20 * 1.5 internal thread quick connector.
7, current / voltage interface: ф4 standard banana plug.
8, the use of temperature: water medium (5 ~ 50) ° C, other media (-5 ~ 50) ° C.
9, the model is complete, you can choose the built-in pressure module, external pressure module, desktop or portable. The pressure module can cover the full range and the middle gear.
10. When the built-in pressure module is selected, the pressure module can be automatically switched without overvoltage damage. Built-in module lifetime free warranty.
11. Two-channel calibration can be performed, and two field instruments can be verified at the same time.
12. Support the instrument information management, calibration process parameter setting, automatic calibration process, automatic data analysis, automatic tracking of super-points, fast storage of calibration results, downloadable tasks, and uploading data.
13. It has a filter anti-blocking and sewage system. The hydraulic table adopts stainless steel pipe with inner hole φ6mm. The impurities or dirt brought by the on-site instrument can be easily discharged from the sewage. Even if it is placed in fine sand, it will not be damaged. Settings. The gas station is equipped with a gas-liquid separator as standard to prevent the liquid in the calibration meter from entering the calibration table.
14. Adopt intelligent voltage regulator, designed according to China's pressure verification procedure. When going up, it will approach the verification point from bottom to top. When going down, it will approach the verification point from top to bottom, but adjust.
15. The type approval is obtained by the automatic pressure calibration table, and the automatic pressure calibration table can be used for standard construction. Other manufacturers can only build the standard with digital pressure gauge.
16. With complete protection function, over-voltage protection (if the 110% of the range is over, an alarm will be issued), over-current protection (when the transmitter current exceeds 22 mA), leakage, sensor failure and other alarms. Stop the pressurization when overpressure, overcurrent, or sensor failure occurs.
17, 7-inch true color large LCD touch screen, the operation interface is beautiful and generous.
18, Dimensions: 215 (high) * 280 (deep) * 320 (width) mm. Technical Parameters
