Description
Additel ADT681 NPT2 5BAR Gauge
The Additel ADT681-02-CP5-BAR-N2 compound digital test gauge provides reference-grade calibration metrics for specialized oil, gas, and heavy-duty petrochemical refinery manifolds. Operating smoothly across a low positive and negative spectrum from -1 to 5 bar, this heavy-duty test instrument delivers an economic solution for high-stakes instrumentation validation. Refineries depend on this United States manufactured gauge to conduct reliable laboratory calibrations in volatile processing zones. This digital alternative removes mechanical friction lag, establishing highly repeatable data baselines during formal industrial safety audits and preventative maintenance checks.
Every individual silicon sensor is characterized using microprocessor-based technology before final assembly to generate unique individual coefficients for maximum linearity. This sophisticated micro-architecture actively dampens heavy pressure spikes, providing rock-solid repeatability across complex fuel manifolds and volatile low-pressure gas lines. The housing comes with a robust 1/2″ NPT thread interface, supporting quick bottom mount or panel mount installations based on local workspace limitations. Dust and water proof IP67 protection empowers field technicians to execute long-term data logging analysis, securing 21,843 internal logs under a 1-year manufacturer warranty.
NPT2 5BAR Instrumentation Metrics
- ISO/IEC 17025 Standard Compliance: Meets strict international metrology criteria to serve as a dependable master instrument for reference laboratories.
- Industrial-Grade 1/2″ NPT Threading: Provides a tight, heavy-duty mechanical seal on high-pressure processing lines without thread binding or leakage.
- Ruggedized IP67 Enclosure Durability: Offers a dust-tight and waterproof housing capable of surviving harsh chemical washdown routines in oilfields.
- Visual Overpressure Sentinel Flash: Uses an automated flashing screen alert system at 120% safety limit to defend the internal sensing element.
- Dynamic % Pressure Graph: Displays real-time capacity parameters via a clear visual fan-shaped graph indicator for fast distant tracking by plant supervisors.
