Pointer Dampening

Eliminate Pointer Flutter

Part No: (abcdeFgghij-k) | Code: (B),(D),(M)

Moderate to intense vibration can make it difficult to record accurate readings. 

Perma-Cal® employs a unique technique which dampens the pointer to reduce flutter and enhance readability.

Pointer dampening is recommended in all applications except where ambient temperatures fall below -35°F (-37°C).

 

No need for liquid fill

Internal pointer dampening and Direct Drive technology eliminate the need for liquid fill, a primary culprit to the premature failure of C-tube gauges.

Pointer dampening is accomplished by proprietary methods using viscous silicone oil.
