Druck DPI 611 Hand-Held Pressure Calibrator

Introduction

The DPI 611 is a fully self-contained pressure test and calibration system. It combines pressure generation, signal measurement, and loop power, offering the convenience of previous models like the DPI 610/615 in a significantly smaller, more accurate, and user-friendly package.

This document details its features, engineering, capabilities, specifications, and accessories.

Product Overview

The DPI 611 represents the fourth generation of the DPI 600 family, which revolutionized portable test and calibration equipment starting in 1984. Building on decades of experience, the DPI 611 offers enhanced performance in a compact form factor.

• 50% smaller and 33% lighter than the DPI 610.
• Generates 0 to 20 bar/300 psi in under 30 seconds.
• Achieves 95% vacuum.
• Pressure measurement is twice as accurate.
• Electrical accuracy is three times better.
• Features a simplified touch screen interface with DASHBOARD, quick TASK selection, and FAVOURITES storage.
• Enables fast, three-touch setup for any application.
• Calculates PASS/FAIL errors, documents results, and interfaces with calibration software.
• Includes one free 4Sight2 Lite calibration software license.

Precision Engineering

Performance is driven by precision engineering, utilizing carefully selected materials, high-tolerance machining, and perfect finishes. The case material and precision molding ensure the DPI 611 is rugged and weatherproof. Advanced analog and digital microelectronics provide class-leading pressure and electrical capabilities with a simple-to-use interface.

Pressure Generation

The DPI 611 can generate pressures from 95% vacuum to 20 bar/300 psi. A simple selector allows conversion between vacuum and pressure modes. Fine adjustment is achieved via a built-in volume adjuster and a precision vent valve for falling calibration points.

• Redesigned mechanical system for improved performance, allowing 20 bar/300 psi generation while holding the instrument.
• Quick pressure generation (30 seconds for maximum pressure).
• Ergonomic design with an adjustable hand strap and soft over-molding for a secure grip.
• Proven mechanical design offers a dependable system without the drawbacks of electromechanical devices.

Pressure Accuracy

Utilizing advanced silicon technology, the digitally corrected "Druck" pressure sensor offers 0.0185% FS accuracy, an improvement over the DPI 610/615. Considering stability and temperature errors over a one-year calibration period, the DPI 611 is more than twice as accurate as its predecessor.

Electrical Capability

The DPI 611 retains the comprehensive electrical measurement and sourcing capabilities of the DPI 610 series, with enhanced accuracy and simplified connections. The mA measurement accuracy is three times better than the DPI 610 series, accounting for stability, temperature, and calibration uncertainty over one year.

Electrical connectors are rationalized to four 4mm sockets for ease of use.

An optional external pressure sensor, P2 IDOS, is available.

Truly Hand-Held

The DPI 611 is designed for true hand-held operation, being 50% smaller and 33% lighter than the DPI 610. Redesigned pressure assembly and state-of-the-art microelectronics contribute to its efficiency, performance, and reduced power consumption. Despite its smaller size, the touch display is nearly twice as large for improved visibility.

Quick-to-Fit Pressure Connections

The DPI 611 features a quick-to-fit adapter system designed to make leak-tight pressure connections in the field easier and faster. All adapters, hoses, and accessories are simple to fit without tools or seals, ensuring leak-free connections. Damaged adapters can be replaced easily, minimizing downtime.

Simplified Touch Screen Interface

The DPI 611 uses an interface similar to the award-winning DPI 620 Genii. The DASHBOARD allows quick application selection. The TASK menu offers popular configurations, and the FAVOURITES menu provides quick access to frequently used tasks. The touch screen dynamically displays only necessary function keys, simplifying operation compared to complex keypads. Application connection diagrams are viewable on screen.

Easy Operation:

1. Swipe from right to left.
2. Touch to make a selection.
3. Touch to select the TASK.
