Accurate temperature measurement is critical in many industrial and laboratory settings. When processes depend on precise temperature control, the choice of sensor can make all the difference. A Pt100 Class A RTD sensor offers reliable, repeatable readings across a broad temperature range, making it a trusted solution for demanding environments.
Why Choose Pt100 Class A RTD Sensors?
Pt100 sensors use platinum resistance to measure temperature, providing excellent stability and accuracy. The Class A rating means the sensor meets strict tolerance standards, ensuring measurements are consistent and precise. This level of accuracy is essential in applications where even small temperature variations can impact product quality or safety.
The sensor operates effectively from -50°C to +300°C, covering a wide range of industrial and laboratory needs. Whether monitoring HVAC systems, controlling chemical processes, or conducting scientific experiments, this RTD sensor delivers dependable performance.
Durable Design for Harsh Conditions
The sensor’s probe is made from 304 stainless steel with a 6mm diameter, offering strong resistance to corrosion and mechanical damage. This robust construction allows the sensor to withstand tough environments such as industrial plants, laboratories, and HVAC installations.
A ½" BSP threaded fitting simplifies installation, providing a secure, leak-free connection to tanks, pipelines, or process systems. This feature reduces downtime and maintenance costs by ensuring the sensor stays firmly in place during operation.
Easy Integration with Existing Systems
The sensor includes an integrated terminal block, making wiring straightforward. This design supports quick connection to transmitters or control systems without the need for additional adapters or complex wiring setups. Users can easily replace or upgrade sensors without disrupting existing equipment.
Note that the transmitter is not included by default but can be added as an option. This flexibility allows users to customise their setup according to specific requirements.
Available Lengths and Custom Options
Standard probe lengths are stocked at 100mm, 150mm, 200mm, and 250mm, covering most common applications. For specialised needs, custom lengths are available with a lead time of 5 to 10 business days. This ensures the sensor fits perfectly in unique installations or specialised equipment.
Typical Applications
Industrial process control where precise temperature monitoring ensures product consistency and safety
HVAC systems require accurate temperature regulation for energy efficiency and comfort
Scientific research and laboratory environments demand reliable data for experiments
Food and pharmaceutical monitoring to maintain strict temperature standards for safety and quality
Equipment diagnostics to detect overheating or abnormal conditions early
Practical Tips for Using RTD Sensors
Ensure the sensor probe length matches the application to avoid inaccurate readings from temperature gradients.
Use the ½" BSP fitting to secure the sensor tightly and prevent leaks in pressurized systems.
Regularly inspect the stainless steel probe for signs of wear or corrosion, especially in harsh chemical environments.
Pair the sensor with a compatible transmitter for digital output and easier integration with control systems.
Calibrate sensors periodically to maintain accuracy over time, especially in critical applications.
