Product Description:

The CWY1006 portable full-automatic pressure calibration bench can automatically calibrate pressure transmitters, Hart and Pa bus intelligent transmitters, pressure switches, digital pressure gauges, pressure sensors, I/P controllers/positioners, general-purpose pressure gauges, precision pressure gauges, pressure indicators, and other pressure instruments.

Feature Description:

• Protection: Overvoltage, overvoltage sensor failure, etc. protection.
• Loop Power Supply: DC24V/30mA.
• Pressure Fitting: M20x1.5 internal thread quick connector.
• Current/Voltage Interface: Standard banana plug with a φ4 diameter.
• Operating Temperature: (-5 ~ 50)°C
• You can choose from built-in pressure modules, external pressure modules, or pressure modules covering the full range.
• When selecting the built-in pressure module, the module can automatically switch, preventing over-pressure damage.
• Dual-channel verification is available, allowing simultaneous verification of two on-site instruments.
• Supports instrument calibration information management, calibration process parameter setting, automatic execution of the calibration process, automatic data analysis, automatic marking of out-of-tolerance points, and quick storage of calibration results. Download tasks and upload data are available.
• Equipped with a filtration anti-blocking drainage system, the hydraulic stand uses φ6mm stainless steel pipe for its inner bore. Impurities or dirt brought by the on-site instruments can be conveniently drained through the drainage port. Even if fine sand is placed at the calibration instrument interface, it will not damage the setup.
• Utilizing an intelligent voltage stabilizer, designed strictly in accordance with China's pressure calibration regulations. During the upward stroke, it approaches the calibration point from bottom to top, and during the downward stroke, it approaches the calibration point from top to bottom, without adjustment.
• Complete protection features include over-voltage protection (an alarm will sound if it exceeds 110% of the range), over-current protection (when the transmitter current exceeds 22mA), leakage, sensor failure, and other alarms. Pressure will stop when over-voltage, over-current, or sensor failure occurs.
