The BH series sensors feature a protective shell, offering durability and can provide continuous, reliable, and real-time displacement signals in harsh environments. The sensors are sealed with a fully stainless steel shell, fully meeting the protection level IP68. Note: The electronic compartment is not removable.
Due to the use of non-contact measurement technology, the sensor can be integrated into a sealed housing isolated from the outside environment. The position magnet moves along the measuring rod, allowing for position measurement without mechanical contact. For level measurement, an optional float can be used. Sensors with protective-grade housing are easy to install and use, better meeting application requirements. Measurement accuracy and all technical parameters depend on the output characteristics of the selected sensor, with interface options available: analog or SSI.
