Liquid-filled pressure gauge 113.53 in a stainless steel housing, dia 100 mm, -1-+1.5 bar, M20 x 1.5 7344698

Glycerin-filled pressure gauge model 113.53 for pressure measurement

Model 113.53 is a glycerin-filled pressure gauge designed for precise pressure measurements in industrial applications. The stainless steel construction and glycerin filling enable operation under conditions with high dynamic loads.

Construction and technical parameters

The stainless steel housing provides resistance to corrosion and aggressive industrial media. The 100 mm dial diameter allows for reading from a greater distance, which is important in industrial environments with limited access to measurement points.

The copper alloy mechanism ensures measurement stability and long-term device operation. The 1.6% accuracy class allows for obtaining reliable measurement results in accordance with the international standard EN 837-1, which is crucial when controlling technological processes requiring high precision.

The M20 x 1.5 process connection located in the bottom position enables easy installation and access to the connection point. The glycerin filling dampens vibrations and oscillations of the internal mechanism, extending the device's service life and improving reading stability during operation under dynamic load conditions.

Industrial applications and media compatibility

The pressure gauge is used in hydraulic systems, where pressure monitoring is key to the safety and efficiency of processes. It is particularly recommended for condenser installations, where significant pressure changes and the risk of mechanical vibrations occur.

The device is adapted for use with chemically inert gases and liquids that do not react with the copper alloy of the internal mechanism. This includes water, air, and other media commonly found in industrial and HVAC installations.

The measuring range is -1 to +1.5 bar, allowing for the monitoring of both vacuum and positive pressure in ventilation, air conditioning, and small hydraulic systems. The maximum medium temperature of +60°C enables operation in most typical industrial applications.

User advantages and operating conditions

The IP65 protection rating guarantees the housing is sealed against dust and low-pressure water jets, enabling installation even outdoors or in high-humidity environments. The polycarbonate window maintains transparency over a long period of operation without yellowing or clouding.

The shock and vibration-resistant construction eliminates the need for frequent calibrations and replacements of damaged devices caused by unstable operating conditions. This reduces installation maintenance costs and minimizes the risk of production downtime.

The temperature stability of the internal mechanism, provided by the liquid damping medium, allows for repeatable measurement results even with significant changes in ambient temperature during normal system operation.
