Multifunction calibrator ADT760 LLP

for mA signalspressurefor pressure sensors

Overview
The ADT760 LLP is a portable, precision, fully automatic differential pressure calibrator designed for measurement and calibration of very low pressures (Delta P) for sensors and transmitters. It automatically generates pressure from 90% relative vacuum up to 75 mbar (±7500 Pa with DP30) and controls generated pressure with stability down to 0.005% of the internal sensor full scale and measurement accuracy up to 0.05% FS.

Key features

• Pressure generation by internal automatic pump (from 90% vacuum to 7500 Pa depending on installed module).
• Control stability: 0.005% of internal module full scale.
• Measurement accuracy up to 0.05% FS; optional ADT155 internal modules for reduced ranges and higher accuracy.
• Interchangeable internal pressure module (ADT155 series).
• Color touchscreen interface (800×480 TFT).
• Measure and simulate electrical signals (mA / V) for transmitter tests; current output 0–24 mA, accuracy 0.01% reading + 0.005% FS.
• 24 VDC loop power output (protected up to 30 V).
• Test automation, recording and data logging (optional DL models).
• HART support (optional by model).
• Rechargeable Li-ion battery (~10 hours operation).
• Portable: weight <1.8 kg; dimensions 235×110×70 mm.

Applications and extensions
For very low pressures and increased accuracy, the ADT760 LLP can be fitted with ADT155 internal sensors (reduced ranges, e.g. ADT155 DP025: 62 Pa with 0.003 Pa stability and 0.13 Pa accuracy). Two digital ADT160A pressure modules can be connected to extend measurement range. The automatic pump provides pressure generation and setpoint control with the precision of the installed internal module.

Electrical and automation functions

• Current measurement: ±30.0000 mA, resolution 0.1 µA, accuracy ±(0.01% reading + 0.005% FS), impedance <10 Ω.
• Voltage measurement: ±30.0000 V, resolution 0.1 mV, accuracy ±(0.01% reading + 0.005% FS), impedance >10 MΩ.
• Current output: 0.000–22.000 mA, resolution 1 µA, accuracy ±(0.02% reading + 0.01% FS).
• Measure and simulate switch On/Off (3–24 V, PNP/NPN) and automatic switch testing.
• Temperature-compensated measurements (calibration coefficients stored in pressure module).
