Positive Temperature Coefficient Ceramic Heater

It can be fine tuned by changing the voltage to the heater.

Positive temperature coefficient ceramic heater. Positive temperature coefficient ptc heaters consist of specialized heating discs built from advanced ceramic materials. Positive temperature coefficient ptc. Ptc ceramic materials are named for their positive thermal coefficient of resistance i e resistance increases upon heating. And reduces power consumption as operating temperature is reached.

The temperature the heater will hold is decided when the material and the heater is produced. The resistivity of the material increases rapidly with increasing. The heater only works as hard as it has to in order to maintain temperature saving energy and achieving more consistent temperature control of the engine compartment. Their wide range of positive temperature coefficient ceramic elements and related components are used industrial controls equipment and consumer applications.

A thermistor is a type of resistor whose resistance is dependent on temperature more so than in standard resistors the word is a combination of thermal and resistor thermistors are widely used as inrush current limiters temperature sensors negative temperature coefficient or ntc type typically self resetting overcurrent protectors and self regulating heating elements positive. Ptc heaters fall into one of two categories. While traditional fixed resistance heaters employ wires and coils to generate heat ptc heaters use conductive inks printed on thin flexible polymer based substrates. Fin elements or honeycomb forms.

These safe powerful and energy efficient heaters allow for exceptional heat production and transfer within even the smallest spaces. They recognize the unique properties of the ptc heaters that make them more reliable safer cost effective than traditional resistance wire type heaters. Self regulating heaters are made from materials with strong positive temperature coefficient ptc characteristics i e. Ptc ceramic material is semi conductive and when voltage is applied to it.

This simple switch in materials is what makes ptc electric heaters superior to traditional coil electric heaters. Ceramic heaters are usually portable and typically used for heating a room or small office and are of similar utility to metal element fan heaters. Positive temperature coefficient ptc heater electrical mechanical design engineers have been using positive temperature coefficient heaters in the equipment for years. While most ceramics have a negative coefficient these materials often barium titanate and lead titanate composites have a highly nonlinear thermal response so that above a composition.

Positive temperature coefficient ptc heaters are self regulating heaters that run open loop without any external diagnostic controls.
