Conductivity controller / meter type M2136
Software to configure and program the M2136 series.
The M2136 conductivity controller is suitable for water, waste water or pure water conditioning in continuous or batch-type operating modes, for liquid chromatography or for general chemical process monitoring.
Temperature coefficient of the cell is compensated either manually or automatically by an external Pt-100 platinum probe within the range of 0°C to 120°C.
Commercially available conductivity cells -K-factor 0.01, 0.1 and 1.0 cover a dynamic range from 0.01µS to 20mS full scale. An internal synchronous rectifier eliminates the capacitive error currents induced by the cell cable.
Optionally, a galvanic isolated and in the range of 0...20mA programmable output signal for the conductivity signal or temperature is available. By a external 24V signal, the current output can be switched between conductivity- and temperature measuring.
Two floating limit or alarm contacts can be set over the entire range. Each is defined as a normally open or as a normally closed contact.
Supply lines and all other lines, either from or to the conductivity meter, are protected by internal noise limiters against HF-noise.
