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. 

Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation

Welding accessories includes products used in, or related to, processes such as MIG, TIG and resistance.

Welding machines and joining machines include all manner of devices used for welding, brazing and soldering.

Inertial and gyro systems use a combination of accelerometers and angular rate sensors (gyroscopes) to detect altitude, location, and motion. They may also be capable of detecting attitude, position, velocity, temperature, or magnetic field

Video cameras take continuous pictures and generate signals for display or recording. They capture images by breaking them down into a series of lines. This search form does not include consumer devices such as camcorders.

Gyroscopes are designed to measure angular rate or orientation about a given directional vector.

Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input

RTD temperature probes convert the RTD resistance measurement to a current signal, eliminating the problems inherent in RTD signal transmission via lead resistance. 

Temperature probes are used in various temperature sensing applications. Technology options include thermocouple, RTD, thermistor and solid state style probes

RTD (resistive temperature device) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature

Thermocouple temperature probes are bimetallic style probes used for various temperature sensing applications

Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level

Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves
