Advanced pressure calibrators
Our advanced pressure calibrators are essential for ensuring accuracy and versatility in measuring pressure and electrical signals. Designed to be versatile and customizable, they integrate in addition to pressure generation and measurement: datalogger functionality, 24V power supply for transmitters and electrical signal output. They are advanced tools to support the operator, for the most demanding applications.
Technical FAQ:
Advanced pressure calibrators
What are advanced pressure calibrators?
Advanced pressure calibrators are high-performance calibration instruments that combine pressure generation and measurement with integrated communication capabilities (HART, FOUNDATION™ Fieldbus, Profibus), electrical signal measurement (mA, V), temperature measurement, and automated calibration procedure management.
What are advanced pressure calibrators used for?
They are designed to perform complete calibration of high-end pressure instrumentation—including smart transmitters, intelligent sensors, and SIL-rated safety systems—using a single instrument. They also support loop verification, HART configuration, and automatic generation of ISO/IEC 17025-compliant calibration certificates.
In which industries are advanced pressure calibrators used?
They are widely used in accredited metrology laboratories, oil & gas facilities, refineries, petrochemical plants, GMP-regulated pharmaceutical environments, power generation, aerospace, automotive, and any application requiring high accuracy, automation, and full measurement traceability.
What is the difference between an advanced pressure calibrator and a standard pressure calibrator?
A standard pressure calibrator provides basic pressure measurement and/or generation functions. An advanced pressure calibrator offers higher accuracy (typically ≤ 0.01% of reading), interchangeable external pressure modules, integrated HART/Fieldbus communication, mA/V measurement capabilities, complete automation, and calibration management software integration.
What level of accuracy do advanced pressure calibrators provide?
Typical accuracy ranges from 0.005% to 0.02% of reading, depending on the model and pressure module used. Top-tier instruments approach the performance of primary deadweight testers and can serve as laboratory reference standards.
What additional functions do advanced pressure calibrators include besides pressure measurement?
In addition to pressure measurement, they can measure and simulate mA, mV, voltage, RTD, and thermocouple signals. They often include HART/Fieldbus communication, 24 V loop power supply, datalogging, onboard calibration procedure storage, touchscreen interfaces, and Wi-Fi, Bluetooth, or USB connectivity for data transfer.
Can advanced pressure calibrators communicate with HART, FOUNDATION Fieldbus, or Profibus devices?
Yes. Advanced calibrators integrate communication capabilities for major industrial digital protocols, allowing users to configure, diagnose, and calibrate smart transmitters without the need for a separate handheld communicator.
Are advanced pressure calibrators suitable for accredited metrology laboratories?
Yes. Models with accuracies of ≤ 0.02% are commonly used in accredited calibration laboratories as secondary working standards, periodically verified against primary standards. They support the documentation and traceability requirements of ISO/IEC 17025.
Can advanced pressure calibrators operate in fully automated mode?
Yes. Advanced calibrators equipped with integrated pneumatic or hydraulic pressure generation can perform fully automated calibration cycles. The system automatically adjusts pressure to programmed setpoints, stabilizes the output, acquires measurement data, and calculates deviations and uncertainty without operator intervention. ADT760A and ADT760S.
What pressure ranges can advanced pressure calibrators cover?
Thanks to interchangeable external pressure modules, a single advanced calibrator can cover ranges from just a few millibars up to more than 1,000 bar, including gauge, absolute, differential pressure, and vacuum applications.
Can advanced pressure calibrators be used in the field or only in laboratories?
Both options are available. Laboratory models offer enhanced automation and advanced functionality, while portable battery-powered versions are rugged and designed for field use in industrial maintenance and process environments. The choice depends on the required application and mobility.
Are advanced pressure calibrators compatible with calibration management software?
Yes. Advanced pressure calibrators are designed to integrate seamlessly with calibration management software via USB, Ethernet, or Wi-Fi, enabling automatic procedure transfer, data acquisition, certificate generation, and centralized calibration record management.
