The Additel ADT 760 series pressure calibrator is portable and automated with a built-in pump, precision pressure sensor, internal controller, and large touch-screen color display. To generate pressure, simply key in the desired pressure and the Additel 760 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.
The 760-LLP is designed for low pressure calibration. It features a built-in pressure module to ±30 inH2O (±75 mbar) and provides an accuracy of 0.05%FS and control stability of 0.005%FS. Additional internal pressure modules (ADT155 series) are available and provide a variety of ranges down to ±0.25 inH2O (±0.62 mbar). The accuracy and control stability are based on the internal module's span. Measurements can be made in gauge or differential mode.
The 760-D provides differential and gauge pressure measurements, but at a higher pressure range than the 760-LLP. The 760-D covers the range of -12.5 to 35 psi (-0.86 to 2.5 bar) with an accuracy of 0.02%FS. It comes with a choice of internal module with a maximum range to 35 psi. Lower pressure configurations to ±10 inH2O differential can be purchased to improve accuracy at lower pressures.
The 760-MA generates and controls pressure from vacuum pressures up to 300 psig (20 barg) 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 that offer lower pressure ranges for improved performance.
