A digital temperature controller is an electronic device used to maintain the temperature of an item at a constant level. The microprocessor-based technology records electronic temperature levels through the use of a sensor and checks them against the desired set point.

Indicator (in Industrial Instruments)

An Indicator is an electronic instrument used to display the measured value of a process variable from sensors or transmitters. It shows the value but usually does not control the process.

Common Process Variables Displayed

Indicators can display values such as:

• Temperature 🌡️

• Pressure

• Flow

• Level

• pH

• Voltage / Current

How an Indicator Works

1. Sensor/Transmitter measures a parameter (e.g., temperature or pH).

2. The signal (often 4–20 mA or 0–10 V) is sent to the indicator.

3. The indicator converts the signal into a readable digital value.

4. The value is displayed on the screen.
