Fiber optic humidity sensors tr²dent "moist"
tr²dent “moist” enables non-contact moisture measurement before, during or after a drying process.
Thanks to its fiber optic design, the system can be used even in challenging measurement situations, such as high temperatures and with a comparatively long working distance (10 cm). The sensor electronics are placed away from the high temperatures, and the light signals are transported to the measurement point and back via fiber optics. Thanks to our multi-channel technology, tr²dent "moist" offers high measurement accuracy and a wide measurement range.
