WIKA contact pressure gauges: Switching and indicating with a single instrument

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.

1. What are cryogenic gases, and how cold do they have to be?

2. How do cryogenic vessels work, and what is the temperature of the cryogenic gas when it reaches the pressure gauge?

1. Cryogenic gas, or cryo gas, is a medium that was gaseous at ambient temperatures and atmospheric pressures, but has since become a liquid due to cooling and compression. At ambient temperatures and atmospheric pressures, gases occupy a huge volu ...
