APSL501Pneumatic Fully Automatic Pressure Calibration Bench
Product Description
The APSL type 501 series fully automatic pressure calibration bench can have built-in pressure modules or external pressure modules, and can have built-in HART functionality to replace a HART communicator, set or calibrate the range of HART transmitters, force the HART transmitter output current to a fixed value (such as 20mA、12mA、4mA), set linear or square root functions, can perform HART zeroing on the transmitter pressure sensor, and is more convenient to use than a HART communicator.

Product Details
1. Product Overview
The APSL type 501 series fully automatic pressure calibration bench can have built-in pressure modules or external pressure modules, and can have built-in HART functionality, replacing a HART communicator, to set or calibrate the range of HART transmitters, force the HART transmitter output current to a fixed value (e.g.,20mA、12mA、4mA), set linear or square root functions, can perform HART zeroing on the transmitter pressure sensor, and is more convenient to use than a HART communicator.
2. Configurable External Pressure Modules
APSL type 311 series precision pressure calibrator;
APSL type 312 series precision digital pressure gauge;
APSL type 315 series high accuracy intelligent pressure module;
Beta pressure module and calibrator;
DHI table.
APSL type 501 series pneumatic fully automatic pressure calibration bench can be divided into: built-in pressure module pneumatic fully automatic pressure calibration bench, external pressure module pneumatic fully automatic pressure calibration bench, desktop pneumatic fully automatic pressure calibration bench.
3. Performance indicators
Working medium: air, no external high-pressure air source needed during calibration, no need to exhaust air.
Pressure module range: (-100 to 2500) kPa.
Custom calibration range: any value between (-100 to 2500) kPa.
Vacuum can reach-100kPa below, micro pressure can be calibrated±500Pa transmitter.
The internal pipe 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 unit: kPa.
Pressure display resolution: 5 digits.
Accuracy class: Pressure:0.02class or0.05class.
Current:0.02level or0.05level.
Pressure control accuracy: touch screen display ±5 characters.
Standard calibration points: range of0%、25%、50%、75%、100%, automatic return. Can be arbitrarily set with computer.
Custom calibration points: 20 seconds, arbitrary.
Automatic pressure stabilization time at calibration points: adjustable between (10-240) seconds.
Total time for automatic calibration of transmitter (9 points with pressure stabilization): about 5 minutes.
Pressure switch calibration time: about 2 minutes.
With HART handheld communicator function. (See HART screen below)
Safety protection: overvoltage, overcurrent, sensor fault and other protections.
Current input: (1~2) channels, (0~22) mA.
Switch input: dry contact, can detect contact resistance.
Loop power supply:DC24V/30mA, if mistakenly connected to a standard meter, it will not damage the standard meter.
Pressure interface:M20*1.5Internal thread quick coupling.
Current/voltage interface: Φ4 standard banana plug.
Drain port: inner diameter: Φ6mm。
Power supply:220V/50Hz。
Operating temperature: -5℃～50℃
Weight: 19kg。
Dimensions: 300 (H) * 530 (W) * 300 (D) mm.
Automatic calibration software: optional.
