Temperature Indicating Coatings and Materials (53 suppliers)
Temperature indicating paints and materials include labels, paints, crayons, or other markers that change color or shape when exposed to a certain temperature. These products are typically non-reversible and are designed for one-time use.
Temperature Indicators (426 suppliers)
Temperature indicators are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input.
Temperature Probes (822 suppliers)
Temperature probes are devices used to sense and measure temperature. Probe technology options include thermocouple, RTD, thermistor, and solid state types.
Temperature Sensors (753 suppliers)
Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation).
Temperature Signal Conditioners (180 suppliers)
Temperature signal conditioners accept outputs from temperature measurement devices such as resistance temperature detectors (RTDs), thermocouples, and thermistors. They then filter, amplify, and/or convert these outputs to digital signals, or to levels suitable for digitization.
Thermal Conductivity Sensors (16 suppliers)
Thermal conductivity sensors measure the thermal conductivity - the ability to conduct heat - of a material.
Thermal Cutoffs and Thermal Fuses (80 suppliers)
Thermal cutoffs and thermal protectors are nonresetting, thermally sensitive devices designed to protect domestic electrical appliances and industrial equipment from fire. They are sometimes described as thermal one-shot fuses.
Thermal Imagers (350 suppliers)
Thermal imagers detect heat patterns in the infrared wavelength (1 micron to 100 micron) spectrum.
Thermal Profilers (22 suppliers)
Thermal profilers are temperature instruments or recorders that provide temperature profiles for furnaces, kilns, or other continuous thermal processes.
Thermal Switches and Thermal Protectors (594 suppliers)
Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.
Thermistor Temperature Probes (135 suppliers)
Thermistor temperature probes sense temperature by using thermistors, devices made of semiconductor materials which exhibit a large change in resistance for a small change in temperature.
Thermistors (273 suppliers)
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.
Thermocouple Connectors (42 suppliers)
Thermocouple connectors are used to transmit temperature readings from a thermocouple (T/C).
Thermocouple Elements (279 suppliers)
Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. Thermocouples are formed by two dissimilar metals.

Thermocouple temperature probes are bimetallic probes that are used in various temperature-sensing applications. They consist of two wires, each of which is made of a different metallic element or alloy.
Thermocouple Temperature Transmitters (325 suppliers)
Thermocouple temperature transmitters convert the small millivolt output of a thermocouple to a current signal (typically 4-20 mADC) that is immune to noise and voltage drops over a long distance.
Thermocouple Wire (100 suppliers)
Thermocouple wire is used to make or extend thermocouples. The wire connects thermocouples from the sensing point to the point of cold junction compensation (CJC).
