Multifunction calibrator ADT 672

for mA signalspressurefor pressure gauges

Overview
The ADDITEL ADT 672 digital pressure calibrator, based on a microprocessor and silicon sensors, provides reliable, accurate and cost-effective pressure measurements up to 4200 bar. Each sensor is aged, tested and protected before assembly to ensure the declared performance.

Main functions

• Available accuracies: 0.02% / 0.05% / 0.1% of full scale
• Temperature compensation for improved accuracy
• Built-in HART communication with onboard HART communicator
• 24 V loop power for transmitters
• MIN / MAX / HOLD functions
• Dual 6-digit display (6-digit resolution)
• Pressure switch testing
• Measurement and simulation of voltage and current electrical signals
• Recording: datalogger with 30 files of 40 records, manual or automatic mode, adjustable recording interval

Measurement ranges
The ADT 672 series is suitable for gauge, absolute, dynamic and differential pressure measurement. The instrument is HART compatible and can calibrate a HART transmitter without disturbing its HART signal. The integrated HART communicator allows reading and updating calibration-related information directly from the device.

Available units
Pa, kPa, MPa, psi, bar, mbar, kgf/cm2, inH2O (4°C), mmH2O (4°C), inHg (0°C), mmHg (0°C).

Frequency and compensation
Measurement frequency: 3.5 measurements/s. Temperature compensation: -10 to 50°C.

Connections
Pressure connections: for ≤1000 bar: 1/4" NPT male, 1/4" BSP male, M20×1.5 male. For ≥1000 bar: 1/4" HP female or male (Autoclave F-250-C, 9/16"-18 UNF-2B or Autoclave M-250-C, 9/16"-18 UNF-2A). Differential test hose Ø6 mm. Other connections on request.
