Features
- low heat capacity guarantees instantaneous thermal coupling
- excellent electrical insulation with good heat conductivity, taking into account voltage load during lengthy operation
- bifilar wiring design prevents induction voltages generating measurement errors
- characteristic curve of the Pt 100 resistance according to DIN EN 60751
- resistant to stress such as shock, pressure and vibration
- resistant to commercially available impregnating agents, hardening and drying processes
- on request with IECEx or ATEX certification for use in hazardous areas
Application
The different versions of the bifilar SRT's support particularly the special requirements of high-voltage machines. The wide range of possible SRT sizes allows the adaptation to almost any engine size. The bifilar winding compensates voltages induced by external electromagnetic fields.
Structure / Functional principle
An insulated measuring wire is wound around a support body. Usually a platinum resistance wire is used with a nominal value of 100Ω (Pt100). Alternatively, copper or nickel wires can also be used as measuring wire.
