Angled sensor head versions
|
Angled sensor head versions must be expected to show a reduced range compared to axially emitting versions.

Special versions
|
Fiber optics with increased vibration protection (type "-VS")
For applications involving higher mechanical stress such as impacts, acceleration, and movement, fiber optics can be produced with increased vibration protection. A special treatment in these fiber optics reduces friction between the fibers and compensates impacts. Fiber optics with special bonding for high temperatures (type "-T400") Standard bonding is suitable for temperatures of up to 80°C. With special bonding materials temperatures of up to 400°C can be reached. For these higher temperature ranges stainless steel sheathing of type E must be used. Customer-specific versions: Special versions with different complex sensor heads can be produced according to customer requests. |
