What is HART? HART stands for highway addressable remote transducer. HART is a communication protocol for the process instrumentation. It is the global communication standard in process instrumentation. A transducer is a device that is capable to convert the physical variable into a similar electrical signal. HART communication protocol is the most used digital communication …
The smart valve positioners are digital valve controllers. The microprocessor based smart valve positioners with internal logic and advance diagnostics. To operate a valve these valve positioners are designed to convert a current signal to a pressure signal. These provide fast and accurate positioning of diaphragm or cylinder actuators. The smart valve positioner produces the …
Introduction The secondary electronics of a transmitter amplify and condition the weak electrical signals generated by the sensor, so that the signals can be sent over long distances without being degraded by noise, and thus the signals can be used to control devices such as indicators, recorders and controllers. Transmitters use various techniques to transmit …
