Product Introduction:

The CWY1006 portable fully 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.

Features:

• Protection: Over-voltage, over-voltage sensor failure, etc. protections.
• Loop Power Supply: DC24V/30mA
• Pressure Fitting: M20x1.5 internal thread quick connector.
• Current/Voltage Interface: Standard banana plug with a diameter of φ4.
• Operating Temperature: (-5 ~ 50)°C
• Choose from built-in pressure modules, external pressure modules, or full-range pressure modules.
• When selecting an integrated pressure module, the module can automatically switch, preventing overpressure damage.
• Dual-channel verification is available, enabling simultaneous verification of two on-site instruments.
• Supports instrument calibration information management, calibration process parameter setting, automatic execution of calibration process, automatic data analysis, automatic marking of out-of-tolerance points, and rapid storage of calibration results. Tasks can be downloaded, and data can be uploaded.
• Equipped with a filter anti-blocking drainage system, the hydraulic stand is made of φ6mm stainless steel pipe. Impurities or dirt brought by on-site instruments can be easily drained out 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 testing regulations. During the upward stroke, it approaches the checking point from bottom to top, and during the downward stroke, it approaches from top to bottom, without adjustment.
• Complete protection features, including over-voltage protection (an alarm is triggered if over 110% of the range), over-current protection (when the transmitter current exceeds 22mA), leakage, sensor failure, and other alarms. Stop the pressure application when over-voltage, over-current, or sensor failure occurs.
