PRESSURE

Capacitive pressure transmitter
from 1 mBar (by splitting the 10 mbar range)
The Series 41X combines the ceramic measurement cell for low pressure
ranges with the µP electronics 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 RIELS 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 41X Ei).
It is used in explosion exposed areas, where the categories 1 and 2 are
required.
