Pneumatic Level Controller controls the liquid level. The level control scheme maintains a selected level in the surge tank by controlling the water flow rate leaving the vessel. Pneumatic level controller is a means for measuring the level of the stream within the vessel.
A pneumatic motor is a machine which converts energy of compressed air into mechanical work. In industrial applications linear motion can come from either a diaphragm or piston actuator. For rotary motion a vane type air motor is used. Rotary motion vane type air motors are used to start large industrial diesel or natural gas engines. Stored energy in the form of compressed air, nitrogen or natural gas enters the sealed motor chamber and exerts pressure against the vanes of a rotor. Much like a windmill, this causes the rotor to turn a high rate of speed. Reduction gears are used to create high torque levels sufficient to turn the engine flywheel when engaged by the pinion gear of the air motor or air starter.
Pneumatic liquid level control is a magnetically actuated precision-made on/off pneumatic instrument, which integrates the use of a magnetically controlled switch actuator in conjunction with specific displacer configurations to provide liquid level indication and control. It is designed to operate under the corrosive and vibrating conditions related with petrochemical industrial applications such as scrubber level control on level gas compressors for maintaining specific liquid levels and/or for high or low safety alarm indication.
Pneumatic manifolds are pneumatically coupled to pneumatic seed meters on the planting units by air hoses. Pneumatic manifolds have separate exhausts at each block or workstation. Its feature includes lightweight aluminum with anodized or chromate finish, completely deburred using electro-chemical technology and in house assembly capabilities.
