Pressure gauge with switch PGS23.100 , PGS23.160
Wherever the process pressure is indicated locally and at the same time, the circuits also need to be changed, the PGS23.1×0 switchGAUGE model finds its application. Pressure indicators with contact (electrical switch contact) open or close an electrical control circuit that depends on the position of the pointer of the measuring device. The switch contacts are adjustable over the entire scale range (see DIN 16085), and are mostly located below the scale, although in some cases they are also above the scale. The instrument indicator (actual value indicator) moves freely over the entire scale range, independent of the setting.
The limit value setting can be adjusted using a movable adjustment knob on the screen.
The switch consists of several contacts, they can also be set at a set point. Contact activation occurs when the actual value indicator moves above or below the desired set point.
There are different types of switch contacts such as: magnetic shock contact, induction contacts and electronic contact. Inductive contacts can be used in dangerous areas. Electronic contact can be used to trigger programmable logic controllers (PLC).
applications :
Control and adjust processes
Pressure monitoring and circuit breaker control
For gaseous and liquid materials that are not very viscous and do not contain any suspended solids
Contact pressure monitors are used wherever process pressure is to be indicated locally and at the same time limit values are to be monitored. The contacts close or open the circuit switch depending on the pointer position of the measuring device. If the pressure value is significantly higher or lower than the set value, they activate an alarm, hence the term “alarm contact”. Contact pressure monitors are suitable for starting, stopping or changing processes.
