Function 1915D01E The QBE61.2-dp0,5 is an active detector delivering an output signal of DC 0...10 V. The output signal is proportional to the measuring range which has a subrange and an overrange. U 12 V 10 V 0V 2V ∆p Subrange Measuring range Overrange Design features The plastic housing with cover, mounting bracket and the two threaded connection G½A form one unit. The connecting terminals are located under the removable cover. The cable enters through a Pg 11 cable entry gland.

Mounting and installation notes Medium temperatures above 80 °C or below 0 °C make it necessary to install a water trap pipe between the pipe work and the sensor. Mounting orientation: optional, with the exception of the cable entry gland facing upward. The QBE61.2-dp0,5 is supplied complete with mounting instructions and a drilling template.
