Process Indicator

A Process Indicator is a digital display instrument that shows real-time process variables such as temperature, pressure, flow, level, speed, or weight. It receives signals from sensors or transmitters (RTD, thermocouples, load cells, 4–20 mA, 0–10 V, etc.) and provides an easy-to-read indication for operators. When connected with a PLC, process indicators enhance monitoring, troubleshooting, and overall process visibility in industrial automation.

Applications 

• Industrial Process Monitoring (temperature, flow, pressure, level)

• Weighing Systems (load cell indicators)

• HVAC & Building Management (environment monitoring)

• Food & Pharma (batch process visibility)

• Boilers & Furnaces (temperature and pressure display)

• SCADA & Automation Panels (local process display)

Advantages

✔ Real-time visibility of process variables
✔ Easy to install and operate
✔ Increases safety by showing alarms/warnings
✔ Flexible input compatibility
✔ Supports both standalone & PLC-based systems

Disadvantages

✖ Does not directly control processes (indicator only)
✖ Advanced models with communication are costlier
✖ Requires regular calibration for high accuracy
✖ Limited data logging (unless connected to PLC/SCADA)
