Fully Automatic Pressure Calibration Bench (Pneumatic / Hydraulic)
Overview
The APSL501 series Fully Automatic Pressure Calibration Bench comes in a pneumatic version (working medium: air, module range (-100 to 2500) kPa) and a hydraulic version (working medium: transformer oil or pure water, module range (0 to 60) MPa); neither requires an external high-pressure source. It accepts a built-in or an external pressure module and can integrate a HART function that replaces a HART communicator: it sets or calibrates the range of a HART transmitter, forces the HART transmitter output current to a fixed value (e.g. 20 mA, 12 mA, 4 mA), sets linear or square-root functions, and performs HART zeroing of the transmitter's pressure sensor—more convenient than a hand-held HART communicator.
Product Overview
The APSL501 series Fully Automatic Pressure Calibration Bench supports built-in or external pressure modules and can be equipped with integrated HART function to replace a HART communicator. It can set or calibrate the range of HART transmitters, force the output current of HART transmitters to fixed values (such as 20mA, 12mA, 4mA), set linear or square-root extraction functions, and carry out HART zeroing for pressure sensors of transmitters, delivering higher usability than a HART communicator.
Configurable External Pressure Modules
APSL311 series Precision Pressure Calibrators;
APSL312 series Precision Digital Pressure Gauges;
APSL315 series High-Accuracy Intelligent Pressure Modules;
Beta Pressure Modules & Calibrators;
DHI Gauges.
The APSL501 series pneumatic fully automatic pressure calibration bench is divided into built-in pressure module pneumatic fully automatic pressure calibration bench, external pressure module pneumatic fully automatic pressure calibration bench and desktop pneumatic fully automatic pressure calibration bench.
Performance Specifications
Working medium: Air. No external high-pressure gas source required during verification, no air venting needed.
Pressure module range: (-100 ~ 2500) kPa.

Accuracy Class:
Pressure: Class 0.02 or Class 0.05.
Current: Class 0.02 or Class 0.05.
Pressure control precision: ±5 digits displayed on touch screen.
Standard verification points: 0%, 25%, 50%, 75%, 100% of range, with automatic return. Arbitrary points can be set when connected to computer.
User-defined verification points: Adjustable dwell time starting from 20 seconds.
Automatic stabilization time at verification points: Adjustable within (10 ~ 240) seconds.
Full automatic verification time for transmitters (9-point stabilization): About 5 minutes.
Verification time for pressure switches: About 2 minutes.
Built-in HART communicator function. (See HART interface below)
Safety protection: Overpressure, overcurrent, sensor fault protection.
Current input: 1 ~ 2 channels, (0 ~ 22) mA.
Switch input: Dry contact, contact resistance detectable.
