Datasheet TP31 TH31

Product catalog summary

Application Range
Temperature sensors of the T.3 series are designed for use in the shipbuilding industry, machinery, and equipment. They measure temperatures of cooling water, lube oil, etc., in engines or gearboxes.

Measuring Principle
The TH3 series uses NTC measuring elements, while the TP3 series uses Pt100 (or Pt1000 on request). Platinum measuring elements offer accurate, reproducible characteristics, and are easy to replace without calibration. NTC elements are semiconductor resistors with a negative temperature coefficient, improving conductivity at higher temperatures.

Dimensions and Connections
Dimensions are provided for the sensor and protection tubes, with specific measurements for length, diameter, and thread types. The protection tubes are available in brass or stainless steel, with various thread options.

Type Code
The type code structure includes measuring principle, construction type, measuring range, and insertion length. Preferred types are available quickly from stock, while special types can be developed upon request.

Catalog excerpts

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 | [email protected]
