Contact & Auxiliary Pointers

Gauge types 10, 11, 13, 14 and 16 may be fitted with auxiliary pointers and electrical or pneumatic contacts during manufacture. The auxiliary pointer may be a simple set hand, externally adjustable to indicate a set pressure, a maximum or minimum pointer carried by the indicating pointer to the highest or lowest pressure, or a combination of maximum and minimum pointers.

Contacts can be simple metal-to-metal, magnetically assisted, inductive or pneumatic for hazardous areas or a built-in single or double micro-switch for increased switching capacity and resistance to vibration. In certain types the case may also be liquid filled to improve resistance to vibration and pulsation.
