RTD Sensors

RTD Sensors

An RTD, resistance temperature detector, is a passive temperature sensing device that operates on the principle that the resistance of a metal changes as the temperature changes. The electrical current that passes through the element...

Temperature Sensors

Temperature Sensors

Temperature sensors are devices that detect and measure coolness and hotness and convert it into an electrical signal. Temperature sensors are utilized in our daily lives, be it in the form of domestic water heaters...

Thermistors

Thermistors

A thermistor, a shortened version of the term thermal resistor, is a passive component whose resistance changes as the temperature in a system changes. Thus they serve as an inexpensive, accurate, and dynamic method for measuring temperature...

Thermocouples

Thermocouples

A thermocouple is a transducer that converts thermal energy into electrical energy and is constructed by joining wires made from dissimilar metals to form a junction. Voltage is produced when the temperature at the junction changes...

Thermowells

Thermowells

A thermowell is a pressure-tight vessel that safeguards and increases the lifespan of temperature sensors in processing plants in cases where a measuring sensor is not otherwise mechanically or chemically useful in...

Cartridge Heater

Cartridge Heater

A cartridge heater is a cylindrical tubular heating device that provides concise and precise heating for various forms of materials, machinery, and equipment. Unlike an immersion heater, a cartridge heater is inserted into a hole in the item to be heated to furnish internal radiant heat...

Heating Element

Heating Element

A heating element is a material or device that directly converts electrical energy into heat or thermal energy through a principle known as Joule heating. Joule heating is the phenomenon where a conductor generates...

Electric Heaters

Electric Heaters

Electric heating is produced by using a known resistance in an electric circuit. This placed resistance has very few free electrons in it so it does not conduct electric current easily through it. When there is resistance in...

Infrared Heating

Infrared Heating

Infrared heating is a heating method used to warm surrounding bodies by infrared radiation. Thermal energy is transferred directly to a body with a lower temperature through electromagnetic waves in the infrared region...
