Baumer AR Precision Test Pressure Gauge - DN 150/200/250 mm

A. Product Overview

The Baumer AR Precision Pressure Gauge is designed for applications where accurate and reliable pressure measurement is required. It is available in DN 150 mm, 200 mm and 250 mm dial sizes, making it suitable for clear reading in laboratories, test benches, calibration setups and industrial plants.

This gauge offers a pressure range from -1 to 0 bar and 0 to 1000 bar with accuracy class 0.25, making it ideal for precision measurement applications. The case is made from AISI 304 stainless steel with bayonet type construction, and optional AISI 316 stainless steel case is available for more corrosive or demanding environments.

The sensing element is made from beryllium copper, while the process connection is made from AISI 316L stainless steel, providing strength, durability and compatibility with industrial applications. Available process connections include 1/4 inch NPT male, 1/2 inch BSP male and 1/2 inch NPT male.

The Baumer AR gauge supports mounting types 1, 2, 3, 5 and 9, giving flexibility for panel, bottom and other installation requirements. It comes with IP65 protection, with optional IP66 and IP67 protection for dusty, wet and outdoor environments. The gauge follows EN 837-1 reference standard.

B. Working Principle

The Baumer AR Precision Pressure Gauge works on the mechanical Bourdon tube pressure measurement principle. When pressure enters through the process connection, it acts on the sensing element inside the gauge.

The beryllium copper sensing element deforms according to the applied pressure. This movement is transferred through the internal mechanical movement system to the pointer. The pointer then moves across the dial and displays the measured pressure value.

Because this model has accuracy class 0.25, the internal mechanism and dial scale are designed for precise reading. Larger dial sizes such as 150 mm, 200 mm and 250 mm help reduce reading error and make the gauge suitable for testing and calibration use.

C. Why It Is Used

The Baumer AR Precision Pressure Gauge is used when normal industrial gauges are not accurate enough. It is suitable for applications where pressure readings must be highly reliable, repeatable and easy to verify.

It is commonly used for pressure testing, calibration comparison, process validation, inspection work, laboratory measurement and high-accuracy industrial pressure monitoring. The large dial size and accuracy class 0.25 make it useful for checking other gauges, pressure transmitters, pressure switches and process instruments.

The stainless steel case improves durability, while the AISI 316L stainless steel process connection provides corrosion resistance at the process side. Optional IP66 and IP67 protection make it suitable for harsh industrial environments.
