Base BM Switch & Flex multi-transmitters

Multitransmitter base BM

The base BM multitransmitter is suitable for use in HVAC systems and cleanrooms. By combining the measurement, conversion, and display of relative humidity, temperature, and differential pressure, it eliminates the need for multiple individual devices, thereby reducing both material and installation costs. With its sleek design, the base BM combines all the relevant features required for the majority of typical applications, offering an attractive price-performance ratio. The compact and smart housing allows for quick and convenient installation in rooms or ducts. A display for showing the measured values is available as an option. Depending on requirements, the base BM is available in two versions: base BM Switch and base BM Flex. Both versions are based on the same product platform but differ in their configuration and application logic.
