Product Description — Baumer Pressure Gauges
Baumer pressure gauges are mechanical instruments designed to measure and display static pressure of gases or liquids within a system using Bourdon tube technology (a curved metal tube that flexes with pressure changes to drive the pointer on a dial). These gauges are widely used in industrial processes, HVAC, refrigeration, hydraulics, pneumatics, water treatment, oil & gas and general automation systems for monitoring pressure and ensuring safe, efficient operation.
⚙️ Core Technical Features
✔ Bourdon Tube Mechanism: Reliable and time‑tested method for pressure measurement.
✔ Stainless Steel Construction: Case & bezel usually made from AISI 304 SS, and Bourdon tube from AISI 316L SS, offering corrosion resistance and durability in harsh industrial environments.
✔ Wide Pressure Ranges: From vacuum/low pressure up to 1600 bar (deep process requirements).
✔ Accuracy: Typical classes around ±1% or ±1.6% of Full Scale depending on model and dial size.
✔ Dial Sizes: Commonly available in 63 mm, 100 mm, 150 mm (larger sizes for high visibility).
✔ Mounting Options: Bottom entry or back entry configurations, surface mounting possible for panel installs.
✔ Standards Compliance: Designed in accordance with EN 837‑1 and ASME B40.100 standards for safety and performance.
✔ Protection Rating: IP65 classification (dust and splash resistant) for many models.
✔ Liquid/Dry Versions: Gauges are offered in dry or glycerin/silicone‑filled versions to dampen vibration and pulsation effects.
Typical Applications
• Industrial Process Monitoring: Measure pressure in pipelines, tanks, reactors and compressors.
• HVAC & Refrigeration Systems: Ensure safe working pressure in chillers, condensers and air systems.
• Hydraulic & Pneumatic Controls: Monitor actuator, valve and cylinder pressures.
• Water & Wastewater: Control pressure for pumps, filtration and distribution systems.
• Food & Beverage / Pharmaceutical: Stainless‑steel gauges for hygienic and clean environments.
• Oil & Gas / Petrochemical: High‑pressure measurement for safety and process control.
��️ Special Variants �� Utility (AA) Series
Economical gauges for general applications like HVAC, air, water, hydraulics & irrigation. Available in various dial sizes with brass or SS wetted parts.
�� Diaphragm Type (AP Model)
Designed for corrosive, viscous or aggressive media that might clog standard Bourdon gauges. Uses a diaphragm sensing element with flanged or screwed connection.
�� Solid Front (AI Model)
High‑safety version with a solid front plate and blow‑out rear for maximum operator protection in pressurized environments.
�� Differential Pressure Gauges
Single or double diaphragm gauges for differential measurement across filters, valves, or flow devices.
�� Benefits of Baumer Pressure Gauges
✔ Robust & Long‑lasting: Built to withstand industrial stresses and corrosion.
✔ Accurate & Reliable Readings: High precision dial and mechanical stability.
✔ Easy to Install & Read: Clear analog dial and multiple connection options.
