Temperature Measurement

How to select the correct Temperature Measurement Sensor and related Peripherals involves an understanding of the measurement technologies and the applications. Here are a few considerations.

Temperature Sensor Selection Questions
  • Temperature range? Sensor technologies work better in particular ranges
  • Accuracy and repeatability? Impacts technology selection and cost
  • Physical installation / geometry:
    • Contact or non-contact? Probes are not always possible, so infrared and thermal imaging may be better
    • Is the process corrosive, high vibration, very high temperature such as a furnace, located in inaccessible area, etc.?
    • How will it be mounted? Wall mount; immersed in a duct, vessel or pipe; thread or flange connection, etc.
    • Is a local display needed?
    • Does it have to send a signal back to a control system or recorder and can cabling be run or would wireless be better?
    • Industry requirements? Food and pharmaceutical industries, for example, often use 3A sanitary connections and require calibration certificates for documentation. Petroleum refineries often require instruments rated for use in hazardous (flammable) areas
