| How to Order |
A Murphy SWICHGAGE® * constantly monitors |
| AT03069 |
| ||
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. |
