Actuator: An actuator is an electric, hydraulic, or pneumatic-powered device that supplies a force and motion for the opening or closing of a valve as the signal is received by the controller. An actuator is also used for the sequencing of valve operations. Control Valve: It is a valve that controls the rate of flow …
What is a compressor? A compressor is a mechanical device that lowers a gas’s volume while raising its pressure. One particular kind of gas compressor is an air compressor. Pumps and compressors have characteristics in that both raise the pressure on a fluid and can move it via a pipe. Since gases may be compressed, …
Pressure Transmitters Pressure is one of the most common properties to detect. We frequently sense differential pressure to determine fluid flow, liquid level, and equipment performance. Pressure transmitters can be designed to measure absolute pressure or gauge pressure. All sensors will sense pressure above atmospheric. Most, but not all, will measure pressure below atmospheric (a partial …
