Operation
A Murphy SWICHGAGE
®
* constantly monitors
pressure, level, temperature or load. Adjustable high
and low contacts on SWICHGAGE
®
are set slightly
above and below desired operating point. When
demand changes, pointer touches appropriate high
or low contact and signals speed change.
AT03069 controller responds only so long as con-
tact is made. The controller stops immediately when
contacts separate. Slow, smooth action prevents
“hunting” or “surging” on normal applications.
*
Mercury tube or snap-action switches are not suitable for this
type control. For more information, recommendations and
quotations contact our engineering dept.
