Multifunction calibrator ADT 760

for mA signalspressurevoltage

Overview
A portable, precision, fully automatic pressure calibrator, compact and lightweight (≈1.8 kg) capable of generating and measuring pressures from 90% vacuum to 20 bar depending on the model. Color touchscreen and internal automatic pump. NIST-traceable calibration certificate supplied as standard.

Functional summary

• Automatic pressure generation and control via integrated pump (up to 20 bar depending on model).
• Control stability of the internal module: <0.005% of full scale.
• Accuracy up to 0.01% of full scale (depending on model/option).
• Interchangeable internal pressure modules to adapt range and accuracy.
• 800×480 TFT color touchscreen for icon-based control and navigation.
• Electrical functions: mA/V measurement and source, 24 VDC loop power (protected up to 30 V).
• Communications: USB, WiFi and Bluetooth; HART instrument support (option).
• Data logging option (DL models): programmable tasks and storage up to 1 million records.

Available models

• ADT760-LLP: designed for very low pressures (module ±30 inH2O / ±75 mbar included).
• ADT760-D: covers -0.86 to 2.5 bar (CP35 sensor included) for differential and gauge measurements.
• ADT760-MA: covers -0.86 to 20 bar (CP300 sensor included), includes internal barometric sensor for absolute and gauge measurements.

Functions and key points

• Test automation (DL models): automatic calibration procedures, task preparation, automatic step control, automatic switch tests with damping.
• Electrical measurement and simulation: mA/V measurement accuracy ±(0.01% reading + 0.005% FS), 0–24 mA source accuracy ±(0.02% reading + 0.01% FS).
• Recording & task management (DL models): up to 250 programmable tasks and result download to PC.
• Leak test: hold pressure to measure leakage losses.
• Pressure circuit protection: upstream special filtering to avoid blockages by dust or residues.
• Removable rechargeable Li-ion battery; runtime ≈10 hours.

Internal modules and compatibility (examples)
The ADT155 module series extends or improves accuracy and ranges: ADT155 (DP025, DP050, DP1, DP2, DP5, DP10, DP20, DP30, DP50, DP150, DP300, DP400, DP800, DP1K) and CP modules (CP2, CP5, CP10, CP15, CP30, CP35, CP50, CP100, CP150, CP200, CP300) with variable accuracies according to module and range.
