Bourdon tube pressure gauge 111.12, dia 63 mm, 0-4 bar, M12 x 1.5, rear centric connection 7399077

Precise pressure measurement in a compact housing

The Bourdon tube pressure gauge model 111.12 is a professional measuring instrument designed for monitoring pressure in industrial installations and HVAC systems. The compact housing with a diameter of 63 mm ensures excellent readability of indications while saving mounting space.

Measuring system and mechanical design

The heart of the device is the Bourdon tube system, which transmits deformation proportional to the applied pressure to the pointer via a mechanism. This proven technology guarantees measurement reliability across a wide range of industrial applications.

The modular design allows for various combinations of housing materials, process connections, and nominal sizes. The M12 x 1,5 process connection in a rear-center position simplifies mounting on control panels or directly onto piping installations.

The housing made of black plastic provides corrosion resistance and a lightweight construction. Accuracy class 2,5 guarantees precision of indications suitable for most industrial applications.

Industrial applications and versatility

The device is ideal as a general-purpose pressure gauge for measuring the pressure of gases and liquids that are chemically inert to copper alloys. It is particularly recommended for:

• Pneumatics - monitoring compressed air in automation systems
• District heating - pressure control in heating installations
• Ventilation and air conditioning - supervising the operating parameters of HVAC systems
• Medical technology - precise measurement in diagnostic devices

Construction according to the EN 837-1 standard ensures compliance with international safety and quality standards.

Operating parameters and service conditions

The indication range is 0...4 bar. The mechanism operates reliably in ambient temperatures from -40°C to +60°C, and the medium temperature should not exceed +60°C to maintain the full functionality of the measuring system.

The housing protection rating IP50 protects against dust and small solid particles. A stop pin located at the zero point facilitates calibration and zero-point control before starting measurements. The white scale with black markings provides high-contrast readability during reading in various lighting conditions.
