APG - Model Series NLS -Pneumatic Level Switch
The NLS pneumatic liquid level sensor is designed for use in high viscosity liquids. It is modified to overcome the high viscosity by making the tip of the detecting pipe larger than usual. The NLS is the ideal sensor for applications where electrical power is not available or hazardous conditions exist. Using a diaphragm, the switch is actuated by compression of a captive air column in the detecting pipe beneath the diaphragm.
Unique Level Switch For Viscous Materials
Viscous and sticky liquids can stop a float switch in its tracks. The NLS is the answer.
- Application: Liquids
- Type: Pneumatic
- Low cost - requires only a standard 1/2 in pipe
- Simple installation
- Rugged and reliable
- Long switch life
Long Life
With few moving parts, only a flexing diaphragm, the NLS pneumatic point level sensor lasts long and is very reliable.
Low Power Operation
The NLS requires no power to operate it sensing elements, and provides a dry contact output.
Field Adjustable
Install a ½ in. pipe of your choosing in the bottom of the sensor housing, protruding past the switch point in the tank. The switch point is easily adjusted by your choice in pipe length.
