Atmospheric Pressure Transmitter / Model Number MC8BRS-971S-D
Supply voltage DC 8-35V, current consumption <4mA, suitable for battery and solar panel power applications, analog output is 4-20mA.
PBS860/880 is an analog output transmitter for atmospheric pressure measurement. By adopting a piezoresistive element, it enables extremely high precision and stable measurement of atmospheric pressure. It also excels in long-term reproducibility, has low hysteresis, and maintains stable performance against temperature changes. Depending on the model, it converts to a linear analog output of either voltage or current. It is also equipped with a potentiometer for offset (zero) adjustment.

Applications/Examples of results
Installation and Connection of Static Ports If you purchase an atmospheric pressure transmitter with an optional static port (order code: MC8BRS-9X1S-SP001), it will be assembled and shipped from the factory. (The weight of the static port is 200g, and when mounted with a bracket, it is 570g). Additionally, the connection of the static port to the atmospheric pressure transmitter will be made during manufacturing. For the connection between the static port and the atmospheric pressure transmitter, a silicone tube (inner diameter 3mm, outer diameter 6mm) that is highly durable against UV and climate change will be used. The plastic parts of the static port are made of ASA resin, and when cleaning, please use a detergent suitable for this material.
