Engineering notes The QBE61.3-DP.. and all interconnected devices must be wired to the same G0/G(measuring neutral). Also refer to the Data Sheets of the devices to which the sensor is connected. The differential pressure at the sensor may never exceed the permissible overload on one side (refer to “Type summary”). High static pressure can destroy the sensor if it acts on only one side of the measurement system. This can be prevented by using the following layout: A...
