Multitransmitter base BM Switch

The base BM Switch multitransmitter was developed for cost-sensitive applications where multiple measured variables need to be recorded in a compact device and flexibly adjusted on-site. This model is based on the same product platform as the base BM, but is designed for particularly easy switching in the field. The humidity range is fixed at 0…100 %rH. For differential pressure, a suitable pressure variant is first selected; within this variant, the measurement range can be switched directly on the device. The temperature range and output signal can also be adjusted directly on the device. This makes the base BM Switch particularly suitable for changing requirements, standardized inventory management, and applications where the final configuration is determined only in the operating environment. The mounting type and filter material are selected to suit the application. A display is available as an option.
