Absolute pressure gauge with switch contacts

Published on : Tuesday 30-11--0001

Wherever the process pressure has to be indicated locally and, at the same time, limit values must be monitored, contact pressure gauges find their application. The switch contacts make or break the circuit dependent upon the pointer position of the indicating measuring instrument. If the reading is significantly above or below a set value, they trigger an alarm, hence also the term “alarm contact”. Contact pressure gauges are also suitable for starting, stopping or switching processes.

Applications

• Measurement of absolute pressure excluding the effect of barometric pressure
• Suitable for corrosive environments, gaseous or liquid
• Monitoring of vacuum pumps
• Control of vacuum packing machines
• Monitoring condensation pressures and determination of vapour pressures of liquids

Special features

• High overpressure safety
• All welded construction of pressure and reference chamber and therefore a higher long-term tightness
• Manipulations of the system impossible DT- GM 86 08 176
• Gauges compatible with alarm contacts and transmitter
• Scale ranges from 0 ... 25 mbar absolute pressure
• with Switch Contacts
