Product Details: Conductivity sensor type M3836
The M3836 conductivity sensor series suitable for water, waste water or pure water conditioning in continuous or batch-type operating modes, to control concentration in cooling towers or for general chemical process monitoring.
The actual measuring value is sent out on the loop powered two wire connection or in case of RS485 Modbus RTU the unit is supplied with 24DC and connected on the 2 Modbus lines.
All settings are conveniently done with the MOSTEC M2428 Data interface and a PC for the loop powered 4 … 20mA Version. Like this, the sensor can be programmed or recalibrated on site without the need to dismount.
The instrument comes with a galvanically separated power supply to maintain galvanic separation between the electrode path and the output signals. Therefore, ground loops between the output signal and the electrode path via the measured media are eliminated.
The temperature compensation can be set manually or done automatically by the internal precision Pt-1000 temperature sensor built into the conductivity probe. A broken wire of the temperature probe leads to an alarm.
The instruments current output can be programmed to any measurement range. For example: 500 to 1000uS equals 4 … 20mA
With the standard MOSTEC conductivity cells a range of 0.055uS to 200mS can be achieved. For ultra-pure water, the C=0.01 cell is used, for higher conductivities, the C = 0.6 six electrode cell covers the rest of the range. Since the transmitter electronics with the microcontroller sits on top of the sensor, the cable length is no longer relevant. A standard shielded cable with two inner wires can be used to connect the sensor.
