The Additel ADT273EX Intrinsically safe barometric pressure calibrator has an optional HART communications capability. The Barometric version has a range of 60kPa to 110kPa. The ADT273EX has passed the most stringent ATEX, IECEX, CSA, and UKCA intrinsic safety certifications from authoritative organizations. Also its explosion-proof level is Ex ia IIC T4 Ga.

Functional Features

Scaling

User can convert measured current, voltage and frequency values into pressure, temperature and flow values. Three conversion functions available: linearity, square and square root

Filtering

Average sliding filter (sampling number: 1 ~ 50) First-order linear filter (First-order coefficient: 0.01 ~ 1)

Switch

The measurement value will be automatically displayed at the moment the switch change of state. The latest 8 state changes will be stored in the memory.

Pressure Tare

Tare value is set through the user interface

Pressure stability indicator

Stability time and criteria is selectable
