Pneumatic Level Sensor

Sticky or corrosive liquids.

Pneumatic level sensor.

Cylinder position sensors from grainger can help detect the position of a pneumatic cylinder count piston cycles or confirm cylinder operation in automated machinery. Resistant to sticky or corrosive liquids suitable for corrosive liquids as they make contact only with the detector and not with the controller. Low power operation the nls requires no power to operate it sensing elements and provides a dry contact output.

Pneumatic devices use air pressure to perform their functions and float valves contain a buoyant float that detects the liquid level and controls the opening and closing of the pneumatic output valve accordingly. Force balance pressure transmitters or pneumatic pressure transmitters first we have to know that the force balance pressure transmitters are very old concept which uses pneumatic air signals for transmitters operation. Limited movement achieves long service life. Pneumatic level sensor fp applications.

For emptying oper ation the end of the dip tube low 1 or end of extension pipe is placed at the desired low level in the sump a nd the end of the hose high. Pneumatic liquid level sensor the innovative design of the dual level system monitors the presence of liquid at the dip tube end to turn the pump off or on. This article only posted to understand. Typically this pneumatic output is 3 15psig.

Enlarged detector is available to ensure stable detection of sticky liquids. Shop now for free shipping on orders 49 this version of internet explorer is either no longer supported by microsoft or is obsolete and some features of our store may no longer be supported. Pneumatic float valves are a buoyancy style level sensor with a pneumatic output valve. These are outdated and in today s generation we are working with smart pressure transmitters.

With few moving parts only a flexing diaphragm the nls pneumatic point level sensor lasts long and is very reliable. The output signal from the controller drives a dump valve open to evacuate liquid from the vessel.
