Our quality controls and instrumentation are at work insuring reliable operations for oil and gas production and transmission, original equipment manufacturing, irrigation and agriculture, power generation, work and pleasure boating-most any application involving engines or their driven equipment. The gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact.
Contacts have a self-cleaning motion to ensure electrical continuity.
The gage mechanism is enclosed in a steel case coated to resist corrosion. Accuracy and protection from moderate overpressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning. When properly installed and maintained, the float operates the pointer which, in turn, both indicates level during normal operating, and closes a switching circuit if the level falls to the low-limit set point. Explosion-proof version of EL150K1 is available.
