APSL601Portable Pneumatic Fully Automatic Pressure Calibration Station

1. Product Overview

This product has obtained 4 independent intellectual property rights (ZL201220302065.8，ZL201220302062.4，ZL201420689202.7，201530021958.4），APSL601The portable fully automatic pressure calibration bench includes pressure generation, pressure measurement, electrical signal measurement, and HART communication functions. It is suitable for verifying pressure transmitters, pressure switches (pressure controllers), pressure indicating gauges, etc.

The APSL type 601 series portable fully automatic pressure calibration bench can have built-in HART functionality, replacing the HART handheld communicator, to set or calibrate the range of HART transmitters, so that the output current of the HART transmitter is at a fixed value (such as20mA、12mA、4mA), set linear or square root function, can perform HART zeroing on the transmitter's pressure sensor. More convenient than using a HART communicator.

• Can fully automatically calibrate pressure transmitters, pressure switches, and pressure indicating gauges.

• Pressure transmitter calibration:

• 1) Standard calibration points: range of0%、25%、50%、75%、100%, automatic return. Custom calibration points: any pressure value.

• 2）Default stabilization time for calibration points: 20 seconds, can be set arbitrarily between (10-240) seconds.

• 3) Total time for automatic calibration (9 points): about 5 minutes.

• 4) Built-in HART protocol, can be used as a hand-held communicator for a smart transmitter.

• Pressure switch verification: can automatically detect the action value and reset value of the pressure switch, and can also detect the contact resistance of the pressure switch.

• Safety protection: overpressure, overpressure sensor fault and other protections.

• Loop power supply:DC24V/30mA, if a standard meter is mistakenly connected, it will not be damaged.

• Pressure interface:M20*1.5Internal thread quick coupling.

• Current/voltage interface: ф4 standard banana plug.

• Power supply:24V Lithium battery, working time 24 hours.

• Operating temperature: water medium (5~50)℃, other media (-5~50)℃.

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

• Dimensions: 215 (H) * 280 (D) * 320 (W) mm.

• Weight:7kg(air pressure);6kg(micro pressure).

3. HART communication
