APSL701High Static Pressure Differential Fully Automatic Pressure Calibration Station

1. Product Overview
The APSL Type 701 Series High Static Pressure Differential Pressure Fully Automatic Pressure Calibration System is a patented product of our company. The patents involved include: 1) Pressure calibration bench with built-in pressure module, patent number:201220302065.8, 2) Fully automatic pressure calibration bench for high static pressure differential pressure transmitters, patent number:201220302053.5, 3) Fully automatic pressure calibration bench based on HART communication, patent number:201220302062.4,4) Fully automatic pressure calibration bench, patent number:201220327679.1,5) Appearance of fully automatic pressure calibration bench, patent number:201230276258.6。
This calibration bench is equipped with high-accuracy static pressure sensor and differential pressure sensor. When calibrating high static pressure differential pressure transmitter, set the static pressure set value and differential pressure range, press "Start" button, the system will automatically perform calibration: first open the bypass valve of differential pressure, automatically add static pressure, when static pressure reaches the set value, automatically according to the set number of calibration points, from the differential pressure range of0%～100% for calibration, automatically record data. If connected to a computer, it can automatically print the calibration report.

2. Performance Indicators
✓Working medium: air or transformer oil; no external high-pressure gas source is needed during calibration, and no need to exhaust air.
✓Static pressure module range: (0-20) MPa.
✓Differential pressure module range: (0-2000) kPa.
✓The internal pipeline diameter is relatively large, and a gas-liquid separator is installed, so it is not afraid of the calibrated meter carrying water or oil.
✓Measurement units: differential pressure: kPa. Static pressure: kPa or MPa.
✓Pressure display resolution: 5 digits.
✓Accuracy: pressure: class 0.02 or class 0.05, current: class 0.02 or class 0.05.
✓Stable accuracy: touch screen display ±5 digits.
✓Standard calibration points: range of0%、25%、50%、75%、100%, automatic return. Can be arbitrarily set when connected to a computer.
✓Custom calibration points: arbitrary.
✓Automatic pressure stabilization time at calibration points: (10～240) seconds, adjustable.
✓Total time for automatic calibration of transmitter (9-point stabilization): about 7 minutes.
✓Safety protection: overvoltage, overcurrent, pressure module fault, etc.
✓Current input: 1 channel,(0～22)mA。
✓Circuit power supply:DC24V/30mA, if mistakenly connected to a standard meter, it will not damage the standard meter.
✓Pressure interface:M20*1.5 internal thread quick coupling.
✓Current/voltage interface: Φ4 standard banana plug.
✓Drain port: inner diameter: Φ6mm。
✓Power supply:220V/50Hz。
