The non-contact anti-dry burning probe (hereinafter referred to as the probe) is a non-contact intelligent anti-dry burning probe based on the principle of infrared temperature measurement. It is mainly used on stoves to prevent fire accidents caused by dry burning of pots. The probe uses advanced infrared temperature measurement technology and algorithms to accurately detect the dry-burning status of the pot and output corresponding signals for early warning. The probe integrates mature optical and circuit design and precision processing technology, and its functions have been verified through a large number of experiments, with superior performance and high reliability.

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
