Capacitive Transmitter Series 41 X / 41 X Ei0 pages

Capacitive Pressure Transmitter
from 1 mbar full range*
/
Series 41 X
Series 41 X Ei
resolution 1 µbar
The Series 41 X combines the ceramic measurement cell for low pressure ranges with the µP
e
­ lectronics of the digital Series 30 transmitter. The pressure values from the signals of the pressure
and temperature sensors are determined by polynomial compensation (see reverse). The values
can be displayed and stored on a PC via an RS485 interface and programming can also be carried
out.
The transmitters are calibrated to the base range. The PROG30 software permits programming of the analog output signal in each section of the range within the base range (e.g. range
100 mbar. Output 4…20 mA for 20…60 mbar).
With KELLER RS converters K-100 Series, up to 128 transmitters can be hooked together into a
bus system and read by means of a PC or laptop. READ30 software allows the current pressure
of each transmitter to be read or the pressure activity of several transmitters to be recorded or
stored whilst “on line”.
This pressure transmitter is also available as intrinsically safe version (Series 41 X Ei). It is used
in explosion exposed areas, where the categories 1 and 2 are required.
