Temperature measurement is required in many parts of industrial processes. From pipelines carrying process fluids to tanks, boilers, and heat exchangers, temperature monitoring helps operators understand and control process conditions.
Although all of these applications require temperature measurement, the sensor requirements may differ depending on the equipment and process. Therefore, selecting the right temperature sensor requires consideration of the actual application and measurement location.
Temperature Sensors for Boilers
Boilers are among the industrial equipment where consistent temperature monitoring is important. Changes in temperature during the heating process can be an important part of boiler operation and control.
A temperature sensor can be installed at the required measurement point and connected to a monitoring or control system. For installations integrated with PLC or DCS, the sensor can be combined with a temperature transmitter to provide a standardized output such as 4–20 mA.
The sensor type and mounting configuration should be selected according to the temperature conditions and measurement point within the boiler system.
Temperature Sensors for Tanks
In tanks, temperature sensors are used to monitor the temperature of liquids or other process media. Temperature measurement may be required for storage applications as well as production processes where temperature needs to remain within a specific condition.
The sensor position is an important consideration in tank applications. Sensor length and installation location should correspond to the tank construction and measurement requirements so that the measured point properly represents the process medium.
When the tank contains chemicals or other specific media, the sensor material should also be considered according to the process conditions.
Temperature Sensors for Heat Exchangers
Heat exchangers transfer heat between two media, making temperature an important process parameter.
Temperature sensors can be installed at the inlet and outlet sides to monitor changes in the temperature of the process media. The measurement can be used for process monitoring and to help the control system maintain the required operating conditions.
For this type of application, sensor selection should consider the process temperature, measured medium, and installation configuration of the heat exchanger.
Temperature Sensors for Pipelines
Pipelines are one of the most common locations for industrial temperature sensors. A sensor can be installed to monitor the temperature of fluids flowing through the pipeline.
The installation point should be selected carefully so that the measurement represents the temperature of the process medium effectively. The sensor connection and configuration should also match the pipeline design and process requirements.
When the distance between the measurement point and control panel is relatively long, a temperature sensor can be combined with a temperature transmitter to convert the sensor signal into an output compatible with the control system.
Selecting a Sensor Based on Process Conditions
The use of temperature sensors in boilers, tanks, heat exchangers, and pipelines demonstrates that one sensor type is not necessarily suitable for every application. RTD Pt100, Type K Thermocouple, and Thermistor each have different characteristics.
In addition to the sensor type, operating temperature, measured medium, sensor material, installation location, and required output should also be considered.
For systems integrated with PLC, DCS, or SCADA, the temperature transmitter configuration should also match the sensor input and control system.
Temperature Sensors as Part of an Instrumentation System
A temperature sensor is not simply a device for displaying local temperature. In an industrial system, temperature measurements can become part of a larger monitoring and process control system.
The sensor can be installed at the required measurement point, while its signal is processed by a temperature transmitter before being sent to the control panel or control room. This allows operators to monitor process temperature without being physically present at the measurement location.
For this reason, sensor selection should be based on the requirements of the complete measurement system rather than simply choosing from the available sensor types.
