Devices to be mounted on pressure gauges in order to obtain an electrical intervention in correspondence with some pressure values, on machines such as engines, pumps and alarms.
The values can be placed all over the scale of the gauge by external adjustable pointers.
In case of vibrations of the installation or pulsating pressures, it is possible to fill the gauge with dielectric oil.
• Chemical, petrochemical, food and pharmaceutical industry
• Aggressive non-viscous liquids
• Aggressive gases
• Glycerine filled in presence of vibrations
Used in normal exercise conditions without vibrations and low switching capacity. It is possible to add a magnetic device to assure contact safety, long life and wide insensibility to vibrations.
- Contact material Ag/Ni alloy gold plated 5 μm
- Max approach of contact 2%
- Break rating 10W/18VA (30W/18VA magnetic contacts)
