RTD Temperature Probes

(428 companies)
RTD (resistive thermal device) temperature probes are types of thermal resistors which measure temperature as a function of resistance.
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.
Resistive temperature device (RTD) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature. They are usually made of metallic elements or alloys such as copper, nickel, or nickel-iron.

Levels

(213 companies)
Clinometers or inclinometers can indicate the angular variation or inclination from horizontal. Laser levels project a spot or indicator onto a surface that is level with the projecting laser level. Machinist's levels are smaller and provide a higher degree...

...photoluminescent), heat resistant, impact resistant, or designed for high-temperature applications. Others are temperature indicating, VOC compliant, waterproof, weatherproof, water repellant, wear resistant, or reflective. UV resistant marking...

Damage Indicators

(28 companies)
Damage indicators are applied onto or within containers and products to indicate that the device has been exposed to environmental factors that could damage the packaged goods.

Laboratory Thermometers

(129 companies)
Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision. Traditional liquid-in-glass design offers ease of use and low cost.

Digital Thermometers

(502 companies)
Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display.

Thermal Profilers

(19 companies)
Thermal profilers are temperature instruments or recorders that provide temperature profiles for furnaces, kilns, or other continuous thermal processes.
Deflectometers and extensometers are used to indicate the deformation of material while it is subjected to stress.

Thermistors

(253 companies)
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.
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.

Thermocouple Elements

(290 companies)
Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. Thermocouples are formed by two dissimilar metals.
Pilot lights and indicator lights are indicating lights for machines or instruments. Most indicators favor the use of LEDs or incandescent lamps.

Thermocouple Connectors

(35 companies)
Thermocouple connectors are used to transmit temperature readings from a thermocouple (T/C).
