Pressure Level controller
Multi Channel Capability

Up to four sensors can be connected to a RIPRESS Controller via 4 … 20 mA or MODBUS RTU. The measured value (typically pressure) is converted into a process value (typically level, flow, volume) by means of an interpolation curve with 20 points. Several prepared functions (interpolation point values) are available for this.
The two analogue outputs (4 … 20 mA) can be used as a correcting variable (PID controller) or as a signal amplifier.  The individual measured values can be recorded and monitored against limit values.

Various preset events can initiate an alarm via SMS, remote interrogation is possible via modem/GSM, data connection to higher-level systems (SPS / SCADA) takes place via MODBUS RTU.

All system parameters can be interactively entered or amended and the measured values displayed via the 6 membrane keys and the graphical LCD. The RIPRESS Controller supports the languages German, French, Italian, Spanish and English.
