Measuring principle Application range Temperature sensors of the T.3. series are especially designed for use in: Shipbuilding industry, machinery and equipment. They measure the temperatures of cooling water, lube oil, etc. e. g. of engines or gearboxes. Measuring principle Temperature sensors of the TH3. series operate with the measuring element: NTC . Temperature sensors of the TP3. series operate with the measuring element: Pt100 (or Pt1000 on request). Functioning of platinum measuring elements With this measuring principle the temperature-sensitive resistance value of the measuring element is acquired. For platinum measuring elements the electrical resistance increases with increasing temperature and decreases with decreasing temperature (temperature linear). Advantages of platinum measuring elements are: • accurate and reproducible thermoelectric characteristics • nearly linear temperature characteristic • easy to replace (no calibration necessary, corresponding to international standards, e. g. IEC 751 / DIN EN 60751) • easier handling towards thermocouples as cold junction is not necessary NTC is a temperature sensitive semiconductor resistor with a negative temperature coefficient. It is a volume resistance that consists of ceramic materials based on metal oxides, such as ferric oxide (Fe2O3), ZnTiO4, and magnesium dichromate (Mg-Cr2O4). With high temperatures the conducting capacity is better than with lower temperatures. Specific features • Compact, robust design • Easy installation via protection tube • Connection with flat connector, lateral cable outlet • Pressure resistance up to 40 bar • Available in different immersion depths • Suitable measuring transducers, limit value switches and analogue indicators available • Sensor with Pt100 or NTC measuring element available Datasheet DB-T.3.-EN | V01.03 | 14/12/2015 | Valid from product revision Rev.- | www.noris-group.com | sales@noris-group.com
