This air temperature RTD Pt100 is ideal for external applications as the connections are enclosed in a weatherproof connection box. It is also most suited to internal applications which require box to be rugged. The sensor itself is housed within a perforated stainless steel tube which allows a free flow of air across the sensor element which in turn will give a good response time. An optional 4 to 20mA transmitter for those requiring a standard transducer signal is also available. Supplied in tolerance classes B or A in a 3 or 4-wire configuration. Operating temperature range: -30ºC to +150ºC.

Frequently Asked Questions

What is an RTD Pt100 sensor, and how does it work?
An RTD (Resistance Temperature Detector) Pt100 sensor measures temperature by detecting changes in electrical resistance. The "Pt" stands for platinum, the material used in the sensing element, and "100" refers to the resistance value of 100 ohms at 0°C. As the temperature changes, the resistance of the platinum element varies, allowing for accurate temperature measurements.
How accurate are RTD Pt100 sensors?
RTD Pt100 sensors offer high accuracy and stability, with industrial-grade elements ranging from Class B (±0.3ºC at 0ºC) to Class A (±0.15ºC at 0ºC). Higher precision options, such as 1/10 class elements, provide an accuracy of ±0.03ºC at 0ºC. These sensors are widely used in industrial, laboratory, and scientific applications requiring high precision. Additionally, we offer calibration services in our UKAS accredited laboratory.
What is the temperature range for RTD Pt100 sensors?
The temperature range of an RTD sensor depends on factors such as the construction, sheath material and insulation used in the construction. While some platinum elements can withstand temperatures up to 850°C, the overall sensor design will limit the maximum temperature rating. Please check the product specifications for the exact temperature range based on the sensor’s construction. If you need any advice, our engineers are happy to assist!
