K-Dyne has been manufacturing both pneumatic and electric liquid level switches for over 20 years. The K-Dyne Model L80 liquid level switch is a displacer actuated level sensor that may incorporate a 3-way pneumatic valve or an explosion proof dry contact electric switch. It utilizes a patented internal direct mechanical action to detect the rise or fall of a liquid level in a tank or pressurized vessel.
The Model L80 may be operated in either a low (direct acting) or high (reverse acting) mode and changing the mode is quick and easy, requiring no special tools or switch calibration. The K-Dyne liquid level switch uses horizontally or vertically mounted displacers and has a wide selection of displacers and rod lengths to meet most installation requirements.
