pin-type RTD sensor, also known as a “surface RTD” or “contact RTD,” is a type of Resistance Temperature Detector that is designed for direct contact with a surface to measure its temperature. It typically consists of a small, cylindrical sensing element made of a temperature-sensitive material, such as platinum, mounted in a metal or ceramic housing.

Here are some additional details about pin-type RTD sensors for surface measurement:

  1. Temperature Range: Pin-type RTD sensors can be customized to measure a wide range of temperatures, from sub-zero temperatures to high temperatures, depending on the material used in the sensing element and the application requirements.
  2. Sensor Type: Platinum is the most common material used for RTD sensors due to its high accuracy, stability, and wide temperature range. Platinum RTD sensors typically have a temperature coefficient of resistance (TCR) of 3850 ppm/°C, which means that the resistance changes by 0.385 ohms per degree Celsius change in temperature.
  3. Mounting Requirements: Pin-type RTD sensors are designed to be in direct contact with the surface being measured. They are typically mounted using a small pin or probe that is pressed against the surface, allowing the sensing element to accurately measure the temperature of the surface.
  4. Sensor Size: Pin-type RTD sensors come in various sizes and configurations, with diameters ranging from a few millimeters to larger sizes, depending on the application requirements and the surface being measured.
  5. Cable Length and Type: The cable length and type can be customized based on your requirements. Common cable types used for RTD sensors include PVC, Teflon, or silicone, with varying lengths to suit different installation needs.
  6. Accuracy and Tolerance: Pin-type RTD sensors can be manufactured with different accuracy levels, typically expressed as a percentage of the temperature range or resistance value. Higher accuracy levels may be achieved through tighter tolerance on the sensing element and better calibration.
  7. Environmental Conditions: The environmental conditions in which the pin-type RTD sensor will be used, such as exposure to moisture, chemicals, or high vibration, should be taken into consideration during customization. Appropriate materials, housings, and protection can be selected accordingly to ensure reliable performance in the intended environment.
  8. Electrical Parameters: Pin-type RTD sensors can be configured with different electrical parameters, such as resistance value, lead wire configuration (e.g., 2-wire, 3-wire, or 4-wire), and current or voltage excitation, depending on your application requirements.
