Keller Swiss-Built Series 46X / 46XEi Submersible transmitters for water level measurements
The Series 46 X combines the ceramic measuring cell for low pressure ranges with the |ìP
electronics of the digital Series 30 pressure transmitters. The signal values of the pressure-
1)
and temperature sensors are determined by a polynomial compensation . The values can be
shown and stored on a PC and can be reprogrammed. A reference tube integrated in the cable
connects the referential chamber of the sensor with the ambient pressure.
Speciications
Pressure Ranges (FS)* 30 100 300 mbar
Overpressure 300 1000 1500 mbar
* Intermediate ranges for the analog output are realizable with no surcharge by spreading the standard ranges
(note that the error band will then increase proportionally)
