Basic function principles
Fig. 4: Bus Terminal block with pressure measuring modules
The pressure measuring modules KM3701 and KM3712 directly record differential and relative pressures in
non-aggressive gases. As in electronic signal acquisition the pressure measurement takes place via a
terminal module. The pressure measuring modules convert the measured pressure into an electrical signal
and make it available to the higher-level controller with a resolution of 16 bits. The measuring principle is
based on the most up-to-date on-chip sensor technology. In addition to just measuring, the semiconductor
also executes other functions, such as temperature compensation and avoidance of long-term drift. The
status LEDs indicate proper function or errors such as range exceedance.
