An I/P transducer is a device that converts an electrical signal into a pneumatic signal for use with pneumatic equipment or valve actuators. You’ll find these devices used in industrial settings. A manufacturing production line that uses liquids, pneumatics or a cooling system during its manufacturing process will have an IP transducer used with other equipment to control the opening and closing of flow valves.
Current-to-pressure I/P transducers convert an electrical signal, typically an analog signal ranging from 4 to 20 milliamps, to a pneumatic or pressurized air signal, set in ranges from 3 to 15 pounds per square inch gauge, 6 to 30 psig, or other flow rates relative to the pressure at sea level. For industrial applications that require a fast-acting process, the I/P transducer will be used in combination with a pneumatic positioner. Ultimately, IP transducers create a communication link between a flow computer and the control valve.
IP Transducers Settings
Another setting you might find an IP transducer is anywhere where an industrial application or process control is needed. For instance, an IP transducer inline with a pneumatic positioner would provide the input to a control valve that would control the mixture of water flow during a process. An IP transducer provides automation to the process instead of relying on manual controls.
You’ll find an IP transducer used in cooling systems when needed to keep equipment at optimum operating levels. For instance, an electronics testing chamber used to conduct tests on electronic equipment or components needs a continually operating cooling system to ensure the chamber doesn’t overheat. A cooling system that uses liquid nitrogen requires a flow control system using pneumatics, a control valve and an IP transducer.
An IP transducer converts the input signal to a proportionate pneumatic output air pressure signal. Depending upon the specific use, an IP transducer may be configured with volume boosters and other control features. While some IP transducers are installed indoors, some require outdoor installations, which mean they must be capable of withstanding the elements. Most anywhere you find operation of valve actuators, damper and louver actuators, relays, web tensioners, clutches and brake and more in industrial settings; you’ll find an IP transducer.
