Pneumatic level sensor.

Typically this pneumatic output is 3 15psig. 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. Low power operation the nls requires no power to operate it sensing elements and provides a dry contact output. With few moving parts only a flexing diaphragm the nls pneumatic point level sensor lasts long and is very reliable.

Pneumatic float valves are a buoyancy style level sensor with a pneumatic output valve. Limited movement achieves long service life.

Cylinder position sensors from grainger can help detect the position of a pneumatic cylinder count piston cycles or confirm cylinder operation in automated machinery. 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 level sensor fp applications. Find a variety of switches here including reed switches and solid state switches in a wide range of sizes.

Sticky or corrosive liquids. The output signal from the controller drives a dump valve open to evacuate liquid from the vessel. Enlarged detector is available to ensure stable detection of sticky liquids. The rotation of the torque tube shaft is converted into a proportional pneumatic output signal by the pneumatic controller attached to the displacer level sensor.

These are outdated and in today s generation we are working with smart pressure transmitters. Pneumatic air pressure sensors pressure sensors monitor relative system pressure in many process applications.
