RTD (resistance temperature detector) sensor can directly connect to secondary instrument by copper conductor, and provide accurate input signal of temperature changes for display instruments, recording instruments, signal conditioners, scanister and computer.

Specification:

1. RTD temperature range and accuracy chart

Note: t is the actual measuring temperature absolute value of the temperature sensing element.
2. Thermal response time of RTD sensor

3. Installing form (unit: mm)

4. RTD sensor connection mode (unit: mm)

5. Selection chart

Tips: Differences between sheath RTD sensor and general thermal resistance
The sheath RTD sensor is the thermal resistance that is soldered and sealed thermistor temperature-sensing element in the sheath wire, which consists of metal casing pipe, insulation material and metal wires. The metal casing material of sheath wire is usually stainless steel. The lead wire is usually copper conductor or silver conductor, and the insulation material is usually magnesium oxide.
There are many characteristics of sheath RTD sensor compared with the general thermal resistance.

1. The external diameter of thermistor can be small, so its time constant is small and reaction speed is fast.
2. It has bendability and is suitable for temperature measurement of complex structure and small equipment.
3. It has good vibration resistance and impact resistance.
4. It has long service life.
