Indicator / Controllers:

Indicator is a device which measures process parameters like Temperature, Pressure, Flow rate, Humidity, pH, conductivity, Level, RPM, displacement, production count etc. Conventional indicators are dial type with a deflecting needle. They are also called as Dial gauge. With the technological advancements in electronics and process instrumentation they are now replaced with Digital Indicators & Controllers. They are either based on digital IC's or Microprocessors. Most of the latest Indicators are programmable and have computer connectivity.
