About Temperature Instruments

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. There are two basic methods for temperature measurement, contact and noncontact. Within these two groupings, an engineer is likely to come into contact with six types: thermocouples, resistive temperature devices (RTDs and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices. This is a generic search form for the selection of instruments, probes and elements used for the temperature measuring industry. Both contact and noncontact style devices are listed. Specific temperature device search forms are also available. 

Specific temperature instrument types include contact temperature instruments, non-contact temperature instruments, digital thermometers, dial thermometers, laboratory glass thermometers, temperature and humidity process controllers, and temperature probes.  Contact temperature instruments are instruments and Indicators designed for temperature monitoring and displaying. These instruments either require a sensor input or come equipped with an integral sensor. Non-Contact temperature sensing devices are typically infrared devices.  Digital temperature sensing instruments are portable, have permanent probe(s) and a digital display. These thermometers are typically battery powered.  A dial thermometer is a bimetal, gas-actuated, or vapor-tension-based thermometer. They display temperature and possibly min/max readings and/or other 'extras'.  Laboratory thermometers are standard glass thermometers for laboratory settings and applications.  Process controllers can be configured specifically for temperature and humidity processes.  Temperature probes include probes for various temperature sensing applications.  Common sensor types include thermostat or thermal switch, thermocouple, RTD element, thermistor, and thermal cutoff.  The temperature measurement range is also important to consider.
