The Additel ADT 761 automated pressure calibrator features a built-in high performance electronic pump and precision pressure controller. To improve its accuracy the Additel 761 has two pressure modules with differing ranges built-in and integrated with the internal pump and controller. It is an ideal solution for calibrating gauges, transmitters, and switches both in the field and in the laboratory.

In a portable package, this calibrator can automatically generate pressures from 90% vacuum to 600 psi (40 bar) with 0.005% FS pressure control stability and 0.02% FS accuracy. With optional external pressure modules (the 160 series), the 761 can measure pressures up to 10,000 psi (700 bar) with 0.025%FS accuracy. In addition to the pressure generation, control, and measurement capabilities, the 761 also features HART communication capability, supplies 24V loop power, and reads the current or voltage produced by the pressure transducers.
