Description
Additel ADT681 150BAR Differential Instrument
The Additel ADT681-02-DP150-BAR high-precision differential gauge provides reference-grade calibration metrics for heavy-duty industrial pneumatic loops and complex hydraulic processing networks. Operating with high-stability silicon pressure sensors engineered for long-term metrological stability, this reference test instrument delivers premium signal integrity for automated calibration benches. Quality control managers deploy this master instrument to verify high-pressure industrial process monitoring systems and trace balancing errors. The robust structural layout withstands severe field handling, replacing unstable analog dial test indicators on critical manifold fluid distribution lines.
Driven by an advanced microprocessor core, this model delivers an exceptional 0.02% Full Span accuracy class with 5-digit resolution stimulus. Active thermal compensation from -10°C to 50°C actively eliminates sensor calculation drift during harsh seasonal outdoor weather fluctuations. Technicians can check operational parameters swiftly by switching between 11 selectable engineering units on a backlit LCD screen equipped with a visual fan-shaped graph scale. An integrated datalogger records up to 21,843 datasets tracking line parameters, while an automated 120% full-scale flash warning system defends the delicate inner hardware paths against overpressure bursts.
High Pressure Differential Metrics
- 0.02% Full Span Accuracy: Guarantees master-class referential precision that satisfies rigid laboratory criteria, significantly lowering risk margins during field transmitter verification.
- Integrated Overpressure Visual Shield: Triggers an automatic flashing screen alert at 120% FS to defend the delicate inner silicon crystal sensor from bursts.
- Multi-Unit Unit Selection: Eliminates manual calculation errors by allowing field operators to switch instantly between 11 selectable pressure units directly from the panel.
- Dynamic Fan-Shaped Graph Scale: Displays real-time capacity percentages on a clear visual indicator for rapid distant tracking by plant supervisors.
- Intrinsically Safe Option Availability: Offers a ruggedized IS-rated housing design configuration built specifically to prevent ignition hazards in explosive volatile environments.
