Description
The Pt100-CSMD Thin-Film Platinum Resistance Temperature Sensor is a general-purpose temperature sensing element with high accuracy, high stability, and high reliability. It is typically made from pure platinum and operates based on the physical principle that the electrical resistance of platinum changes with temperature, known as the temperature coefficient effect.
Compared with leaded thin-film platinum resistance sensors, the Pt100-CSMD series offers a lower-cost surface-mount solution and supports soldering methods such as tin soldering, reflow soldering, and wave soldering. This sensor is suitable for temperature measurement in various liquid, steam, and gas media, as well as on solid surfaces.
Application
The Pt100-CSMD thin-film platinum resistance temperature sensor is widely used in:
- Instruments and meters
- New energy systems
- Household appliances
- Aerospace applications
- Liquid temperature measurement
- Steam temperature measurement
- Gas temperature measurement
- Solid surface temperature monitoring
- PCB-mounted temperature sensing
- Electronic temperature control systems
Features
- Compact SMD package, suitable for PCB-mounted applications
- High precision for reliable temperature measurement
- Excellent long-term stability
- Lower cost compared with leaded thin-film platinum RTD sensors
- Supports tin soldering, reflow soldering, and wave soldering
- Fast response time in boiling water and airflow
- Good vibration and shock resistance
- Reliable performance for electronic and industrial temperature control applications

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.
