A process indicator is used to monitor a wide range of industrial parameters by receiving signals from sensors and transmitters and displaying accurate real-time values. A digital process indicator is commonly installed in control panels to ensure continuous visibility of critical operating conditions across manufacturing and automation systems.

The most common industrial parameters monitored using a process indicator include:

Temperature – Measured using RTD or thermocouple sensors in applications such as furnaces, boilers, ovens, and reactors.
Pressure – Monitored in pipelines, hydraulic systems, compressors, and process vessels.
Flow – Used to track liquid or gas flow rates in chemical plants, water treatment systems, and production lines.
Level – Measures tank or reservoir levels in storage and processing units.
Voltage and Current – Electrical parameters monitored in power panels and distribution systems.
Humidity – Used in HVAC systems, clean rooms, and controlled environments.
pH and Conductivity – Common in water treatment, pharmaceutical, and chemical industries.
Speed (RPM)—Measured in motors, conveyors, and rotating machinery.
