Process Indicators

Mechanical pressure gauge PG 4-row

PG4 Series

Dynisco's series of mechanical pressure indicators is the ideal choice for applications that require simple and maintenance-free pressure indication. The polymer pressure is sensed by a diaphragm that is installed in the process orifice of the machine. In the fixed bar configuration, the display can be rotated 300 ° for a seamless overview. For applications with high temperatures or limited installation space, pressure gauges with a flexible capillary are available to keep the meter away from the process and radiant heat. Configurations that simultaneously sense temperature using thermocouples or RTD are also available.
