Description
MRT-313 is an infrared thermopile temperature sensor, direct contact is not required when measuring object temperature. The core component thermopile chip is formed by connecting hundreds of thermocouples in series based on MEMS technology. The thermopile absorbs the infrared energy emitted from the measured object, and uses the Seebeck theory, the sensor outputs the corresponding voltage to detect the temperature of the target.
Application
- Household appliances (Microwave oven, hair dryers, range hood etc), temperature measuring and controlling
- Non-contact temperature measuring
- Continuous temperature control of production process
- Human presence detection
- Power industry temperature monitoring;
Features
- TO-39 metal package
- Specific perspective
- Quick response
- Good stability
- High precision NTC

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, but the module will be 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 sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
