Description
The Additel ADT761 is a portable automated pressure calibrator that generates and controls pressure with a built-in pump, from vacuum to its rated maximum, without a separate hand pump or gas bottle. It combines pressure control with electrical measurement and loop power, so a technician can run a complete transmitter or switch calibration automatically and store the results. Task presets, a color display and HART support make it a practical choice for instrument shops and field technicians who calibrate large numbers of pressure devices.
Key features
- Built-in pump with automatic pressure control from 90% vacuum
- Fully automated calibration with preset tasks and auto stepping
- External ADT160 series pressure modules extend measurement up to 10,000 psi
- Measures mA and V with 0.01% of reading + 0.005% FS accuracy, sources 0 to 22 mA
- 24 VDC loop supply, automatic switch test and leak test functions
- Stores 120 tasks with result upload, HART instrument support
Typical applications
- Pressure transmitter calibration
- Pressure switch testing
- Gauge calibration in instrument workshops
- Field calibration in process plants
