An outstanding temperature sensor performance is characterized by:
• The element
• Quick and precise reaction
• The packaging
1. Elements
Depending on the equipment different element technologies can be applied:
• RTD (Pt100/Pt1000) - for standardizedsignals and high accuracy the RTD’s are a perfect choice
• Thermistors (NTC/PTC)
- the optimum solution for OEM equipment in large volumes
• Thermocouples
- a well-known technology for high temperatures and heavy-duty applications
If required the temperature sensor can also be delivered with a transmitter to get an analog signal:
• 4-20 mA
• Voltage
• Ratio metric
2. Quick and precise reaction
Special care has been put into the design of the sensor in relation to the reaction time. A specially developed sensor element fixture ensures contact between the element and the housing material in order to secure a fast heat transfer from the media to the sensor element. On top of this, the sensor construction ensures minimum radiation of heat, which results in a measurement very close to the actual temperature of the media.
3. Packaging
The sensor design offers long-life stability through:
• High shock and vibration stability
• High enclosure grade
(special cases up to IP 69K)
• Flexible choice of sensor material:
• Stainless steel (AISI 316)
• Brass
• Gold plated contacts to secure flawless signal
