Automatic handheld pressure calibrator

Technews Industry Guide: Maintenance, Reliability & Asset Optimisation 2017 Maintenance, Test & Measurement, Calibration

The Additel 760 series automatic handheld pressure calibrator takes portable pressure calibration to new levels. Weighing less than 2 kg, the innovative design contains a built-in pump, precision pressure sensor, internal controller and a large touch-screen colour display. To generate pressure, simply key in the desired pressure and the instrument will do the rest. Each unit has four channels: one internal pressure channel for source and measure pressures, two external pressure measurement channels, and one electronic measure and source channel. This series of calibrator has three standard models with the option of adding HART communications, documentation and data logging.

Features

ADT760-LLP

The 760-LLP is designed for low pressure calibration and comes with a built-in pressure module to ±75 mbar and provides an accuracy to 0,05% FS. Users that need to go lower in pressure can purchase additional internal pressure modules (ADT155 series), which for the 760-LLP provide a variety of ranges down to ±0.62 mbar. Measurements can be made in gauge or differential mode.

ADT760-D

The 760-D gives differential and gauge pressure but at a higher range than the ADT760-LLP. Covering the range of -0,86 to 2,5 bar and with an accuracy of 0,02% FS, the ADT760-D is an ideal solution to cover common gauge and differential pressure measurements. The instrument comes with an internal module covering its full range, but lower pressure modules can be purchased to improve accuracy at lower pressures.

ADT760-MA

The 760-MA generates and controls pressure from vacuum pressures up to 20 bar.g with an accuracy of 0,02% FS. Equipped with a built-in barometric reference, each unit can switch between gauge and absolute pressure types. A variety of internal sensors are available which offer lower pressure ranges for improved performance.

Documenting process functionality

Each model of the Additel 760 series has an option incorporating documentation and communication functions turning it into a multifunction documenting process calibrator. This feature provides HART communication, task documentation and data logging.
