Product information "Digital Single point load cell H33A-D"

Digital Load Cell

The H33A-D is a digital load cell made of aluminum. An integrated 24-bit signal amplifier in the cell directly converts incoming analog measurement values (mV/V) into a digital signal and outputs it. This saves costs for specialized external evaluation electronics for conversion and simplifies integration.

Communication is easily achieved through an RS-485 half-duplex interface. Each load cell can communicate separately and independently with the user through the digital output.

The digital load cell H33A-D also provides highly precise and reproducible measurement results even during long-term use. Thanks to its IP65 protection rating, the aluminum measuring body can be used in humid or dusty environments.

Note: Custom cable lengths and alternative connectors are available for larger order quantities. Please send your request to info@bosche.eu.
