You will likely find temperature measurement to be a part of almost every industrial process. It is a mainstay of commercial and industrial processes and operations globally. Accurate measure of process, equipment, or product temperature provides operators with useful information that is utilized in countless ways. The range of available instruments and equipment for measuring temperature in industrial process settings is extensive, with devices or varied types, performance, and form factor to accommodate every application.

There are a variety of instruments and methodologies for measuring temperature, the most common of which is probably direct contact between the target substance and an appropriate temperature sensor. Industrial process applications are commonly served by thermocouples or resistance temperature detectors (RTD), chosen for their cost, accuracy, and flexibility of installation.

Every operating process is "critical" to some group of stakeholders. The process may be of great importance for a number of reasons:
  • The process output may serve as an input to another process with great value.
  • The process output may be of great direct value to the stakeholders.
  • The process may have significant levels of hazard associated with improper or out of control operation.
  • Out of control operation may result in substantial financial loss to the stakeholders.
When temperature is an important indicator of process function, whether for financial or safety reasons, the operator cannot tolerate a loss of the temperature signal. One manufacturer has an advanced solution in the form of a dual input temperature transmitter with built in functions that:
  • Switch to the backup sensor if the primary has a failure indication.
  • Alert the operator if the deviation between the two sensor readings indicates sensor drift. 
  • In wide range temperature applications, switch between sensors with differing measurement ranges for better accuracy.
Along with HART communications and other useful features, these advanced temperature transmitters can help reduce risk and increase performance and safety.
