Review SENSIRION Lot Of Ag Air Quality Thermal Conductivity Sensor

The Sensirion STC31-C-R3 is a highly accurate and reliable CO2 (Carbon Dioxide) in-situ Air Thermal Conductivity Sensor designed for measuring the thermal diffusivity of gases, specifically CO2. This sensor is part of Sensirion's CO2 Sensing product portfolio, which is known for its precision and reliability in various industrial applications.

The STC31-C-R3 sensor operates based on the principle of thermal conductivity. It consists of a small, heated sensing element surrounded by a gas-filled measuring chamber. The thermal conductivity of the gas sample is determined by measuring the temperature difference between the sensing element and the gas sample, and the resulting thermal diffusivity value is then calculated based on this measurement.

The sensor has a measuring range for CO2 of 0-10% vol., with an accuracy of (2% of reading 0.5%) and a typical response time of approximately 30 seconds. The sensor also features a built-in temperature sensor, which allows for automatic temperature compensation to ensure accurate readings even in varying environmental conditions.

The sensor housing is made of stainless steel (V2A) and is suitable for use in harsh industrial environments. It is also compact in size, with a diameter of 18 mm and a height of 31 mm, making it easy to integrate into various measurement systems.

The Sensirion STC31-C-R3 sensor is designed for use in applications where precise measurement of CO2 concentration in air is essential. Some common applications include Indoor Air Quality (IAQ) monitoring, HVAC systems, and process control in industries such as food and beverage production, pharmaceuticals, and laboratories.

The sensor is delivered with a calibration certificate and is easy to use with a wide range of measurement systems, including Sensirion's own SensAIR CO2 Transmitter series. The sensor also features a temperature output signal, which can be easily converted to CO2 concentration using the calibration data provided by Sensirion.

The Sensirion STC31-C-R3 is a high-performance CO2 in-situ Air Thermal Conductivity Sensor that combines precision, reliability, and ease of use in a compact and rugged design, making it an ideal choice for a wide range of industrial applications.
