• long-lasting and reliable
• for rough industrial environments

• no oil leakage, no oil refilling
• no blurry oil colored glasses

Rough industrial work environments with vibrations or sudden pressure changes require a special protection mechanism for the Gauge movement with the needle pointer. 

The standard solution of oil filled gauges achieves a damping effect but requires regular refilling maintenance due to the evaporation of the glycerin oil. Oil leakage due to a mechanical gauge damage can cause potential contamination of the process media. Hot and humid climatic conditions have an effect on the oil color and lead to a milky or blurry display glass window. 

Schmierer has developed, field tested and successfully used mechanically damped pressure gauges with a uniquely designed MANODAMP^® technology in production plants worldwide over the past years.

MANODAMP® Gauges have significant advantages to the “classical” liquid-filled gauge cases:

• No leakage problems with gauge fillings
• No risk of contamination of measured media
• No blurry gauge glass window due to oil colouring after a short time of use
• Suitable in hot and humid climates
• Easy maintenance for needle zero readjustment or change of movement parts
• Long gauge life cycle in rough environment
• Modern up to date construction fulfills the technical and hygienic requirements of chemical, petrochemical, food and pharmaceutical industries
• Economic advantage: no oil refilling maintenance required
• Excellent long term testing results with satisfied customers worldwide

The MANODAMP^® damped pressure gauges retain a smooth pointer movement rough manufacturing environments with vibrations, pulsations, pressure spikes or drops.  This technology operates on a movement of double damped axles (pointer and segment shafts) and a unique construction of the connection to the measuring element with compensating springs. It is used in Schmierer pressure gauges with 100 mm or 160 mm diameter with a pressure above 2.5 bar.
