This movement can be dampened by means of an optionally available liquid filling so that any vibrations have far less impact on the accuracy and stability of the reading. The natural lubricating properties of this liquid filling also reduce wear to moving parts, entry of caustic/corrosive gases and accumulation of condensation. The stainless steel version allows pressure measurement of even the most caustic liquids and gases. These pressure gauges are fitted with a threaded connection at the bottom or on the back.

• Accuracy class 0.6
• Nominal sizes: 160 and 250 mm
• Designs with brass connection and stainless steel housing or completely in stainless steel
• Measuring ranges from –1200…0 mbar up to 0…1600 bar
• With or without liquid filling for vibration dampening
• Fast delivery

The overload protection of 25 mbar amounts to six times the value of the full scale reading. For larger measuring ranges, the overload protection amounts to ten times the full-scale value. The devices are available in steel housings of nominal sizes 63, 100 or 160 with connections at the bottom of the gauge or centered on the back of the housing. Other designs are available upon request.

• Accuracy class 1.6
• Millibar ranges
• Corrosion resistant
• Zero-point correction

Model series PMR04 Bourdon tube pressure gauges can be supplied in brass or stainless steel versions, with filled or unfilled gauges. This movement can be dampened by means of an optionally available liquid filling so that any vibrations have far less impact on the accuracy and stability of the reading. The natural lubricating properties of this liquid filling also reduce wear to moving parts, entry of caustic/corrosive gases and accumulation of condensation. The stainless steel version allows pressure measurement of even the most caustic liquids and gases.

• Nominal sizes: 4"/100 mm, 6.3"/160 mm, 9.8"/250 mm
•  Designs with brass connection and stainless steel housing or completely in stainless steel
• Measuring ranges from -30 inHG…0 psig / -1…0 bar up to 0…25000 psi / 0…1600 bar
• With or without liquid filling for vibration dampening
• Electrical supplementary devices such as limit contacts or analog output signals
• Fast delivery

Diaphragm pressure gauges are unaffected by shock and vibration and can be optionally supplied with high protection against overpressure. With appropriate diaphragm coatings, these devices can be used under rough/extreme service conditions and with caustic/corrosive fluids.

• For caustic/corrosive, highly viscous, crystallizing fluids
• Unaffected by shocks and vibrations
• High protection against overpressure
