Indikator für SYCON 2802:

The SYCON 2802 is a titration device for measuring water hardness or carbonate hardness. Compared to the SYCON 2702, the Onlie analyzer has two additional relays, making a large number of new connection variants possible. There is also an RS485 interface with Modbus RTU protocol and a further input contact. An additional programmable second limit value enables the monitoring of a water overlap or a pre-alarm. The additional relay contacts make it possible to control an external cooling water valve for a sample cooler.

  • Monitoring of a freely programmable limit value
  • Measurement of residual hardness, total hardness or carbonate hardness (acid capacity)
  • Graphic display, menu navigation in German, English, Italian, French, Spanish, Russian, Polish, Dutch and Danish.
  • Simple commissioning using the installation wizard
  • Documentation of all measurement results on an SD card
  • Low maintenance thanks to peristaltic pump technology and flushing the measuring cell with line pressure
  • Self-calibrating against ambient light, contamination and turbidity of the water sample
  • Reliable thanks to self-diagnosis and plausibility monitoring of sensor data during analysis
  • Maintenance-free full color sensor
  • Connections:
    • 4 potential-free outputs:
      • Limit value exceeded
      • Limit value exceeded / limit value not reached / indicator level low
      • Device fault
      • Analysis active / cooling water valve / indicator level low
    • Current interface configurable as 0 – 20mA or 4 -20mA for measured value output or status message
    • Input for potential-free contact for external analysis triggering, water meter for volume interval or pausing the internal analysis interval
    • Input for remote rest via external control
    • Modbus RTU for querying the measured values and device parameters via a PLC
