Portable automatic pressure calibrator

MY-SL605Portable automatic pressure calibratorIt includes pressure generation, pressure measurement, electrical signal measurement, and HART communication functions, suitable for verifying pressure transmitters, pressure switches (pressure controllers), pressure gauges, etc. The portable fully automatic pressure calibrator can be equipped with built-in HART function, replacing the HART controller, to set or calibrate the range of the HART transmitter, force the output current of the HART transmitter to a fixed value (such as 20mA, 12mA, 4mA), set linear or square root function, and can reset the pressure sensor of the transmitter to HART. It is more convenient to use than a HART handheld device.

Function point:

1Portable automatic pressure calibratorCapable of fully automatic calibration of pressure transmitters, pressure switches, and pressure gauges.

2. Pressure transmitter calibration:

(1) Standard calibration points: 0%, 25%, 50%, 75%, 100% of the measuring range, automatic return. Custom calibration point: any pressure value.

(2) The default voltage stabilization time for the calibration point is 20 seconds, which can be set arbitrarily between 10 and 240 seconds.

(3) Automatic verification process time (9pm): about 5 minutes.

(4) Built in HART protocol, it can be used as a smart transmitter's HART handheld device.

3. Pressure switch calibration: It can automatically detect the action value and reset value of the pressure switch, and can also detect the contact resistance of the pressure switch.

4. Security protection: protection against overvoltage, overvoltage sensor failure, etc.

5. Circuit power supply: DC24V/30mA, if mistakenly connected to the standard meter, it will not damage the standard meter.

6. Pressure interface: M20 * 1.5 internal thread quick connector.

7. Current/voltage interface: ф 4 standard banana shaped plug.

8. Power supply: 24V lithium battery, working for one day.

9. Operating temperature: Water medium (5-50) ℃, other media (-5-50) ℃.

10. 7-inch true color large LCD touch screen, with a beautiful and elegant operation interface.

11. Dimensions: 215 (height) * 280 (depth) * 320 (width) mm.

12. Weight: 6kg.

HART communication:

Support calibration of HART intelligent instruments, the operation screen is shown in the following figure:

Rich task management functions:

Support the management of calibrated instrument information, setting of calibration process parameters, automatic execution of calibration process, automatic data analysis, automatic marking of over tolerance, and quick storage of calibration results. Tasks can be downloaded and data can be uploaded.

Portable fully automatic pressure calibrator fully automatic calibration:

1. Fully automatic calibration of transmitters, automatic recording of calibration results, and automatic printing of calibration reports;

2. Fully automatic calibration of pressure switches, automatic capture of upper and lower switching values, automatic recording of calibration results, and automatic printing of calibration reports;

3. Fully automatic calibration of pressure gauges, automatic calculation of errors, automatic recording of calibration results, and automatic printing of calibration reports.

(1) Portable fully automatic pressure calibrator is easy to use:

(2) A user-friendly interface that can display curves.

(3) You can see the instructions on the touch screen.

(4) Automatic leak detection with leak alarm function.

(5) When the battery is low, an AC adapter can be used.

(6) Charging once, wireless standby for one day, inconvenient to use in places where the power supply is not convenient.
