CONMONSense RSV (0-10V Sensor) FAQ

Note that the sensor does need an external 24VDC supply capable to deliver at least 40 mA.

CONMONSense wiring:

1 = 24VDC Power supply (+)
2 = Voltage output (Vout)
3 = 0V (-)
4 = Communication line (should be left floating if not used)

If your system has a dedicated 0-10V analog voltage input, here is a possible wiring:

Note that this wiring is only used as an example, you should refer to your system technical document to ensure a correct wiring with your installation.

Static mode:

Equation for each amplification:


Example: an output voltage of 5 [V] will result in a sensor output voltage of (5 / 25) = 0.2 [V] or 200 [mV] or 106 [dB]µV


Example: an output voltage of 5 [V] will result in a sensor output voltage of (5 / 100) = 0.05 [V] or 50 [mV] or 94 [dB]µV


Example: an output voltage of 5 [V] will result in a sensor output voltage of (5 / 400) = 0.0125 [V] or 12.5 [mV] or 82 [dB]µV


Example: an output voltage of 5 [V] will result in a sensor output voltage of (5 / 1575) = 0.0032 [V] or 3.2 [mV] or 70 [dB]µV


Example: an output voltage of 5 [V] will result in a sensor output voltage of (5 / 6275) = 0.0008 [V] or 0.8 [mV] or 58 [dB]µV


Example: an output voltage of 5 [V] will result in a sensor output voltage of (5 / 25000) = 0.0002 [V] or 0.2 [mV] or 46 [dB]µV

 

Dynamic mode:


Equation for each amplification:


Example: a dynamic output voltage of 1 [V] will result in a sensor output voltage of (1 / 1.2) = 0.833 [V] or 833 [mV] or 118.3 [dB]µV


Example: a dynamic output voltage of 1 [V] will result in a sensor output voltage of (1 / 4.8) = 0.208 [V] or 208 [mV] or 106.3 [dB]µV


Example: a dynamic output voltage of 1 [V] will result in a sensor output voltage of (1 / 19.2) = 0.0521 [V] or 52.1 [mV] or 94.3 [dB]µV


Example: a dynamic output voltage of 1 [V] will result in a sensor output voltage of (1 / 75.6) = 0.0132 [V] or 13.2 [mV] or 82.3 [dB]µV


Example: an output voltage of 1 [V] will result in a sensor output voltage of (1 / 301.2) = 0.0033 [V] or 3.3 [mV] or 70.3 [dB]µV


Example: an output voltage of 1 [V] will result in a sensor output voltage of (1 / 1200) = 0.00083 [V] or 0.83 [mV] or 58.3 [dB]µV

Note that the dynamic mode is an alternative output (AC) with a bias voltage (DC) of 3 [V]. A dynamic output of 1 V means 3 V DC + 1 V AC

In order to modify the internal amplification of the sensors or to switch from static to dynamic mode, a communication needs to be established between the PLC and the sensor.

Using a digital output

If your PLC has a digital output module you can connect one output to the sensor communication line using this kind of schematic:

Then simply generate pulses according to the CONMONSense datasheet in order to modify the amplification or the mode.

Using a serial communication

It is also possible to communicate using a serial communication with the following specification:

• Protocol: UART
• Baudrate: 9600 bps
• Data bits: 8
• Parity: Even
• Stop bit: 1

CONMONSense sensors are using a proprietary protocol described in the datasheet.

The best way to implement an amplification control is by following these simple rules:

Static mode

  • If the output voltage (DC) is higher than 5 [V] decrease the amplification by one step (12 [dB])
  • If the output voltage (DC) is lower than 1 [V] increase the amplification by one step (12 [dB])

Dynamic mode

  • If the signal peak is higher than 4.5 [V] (or 1.5 [V] if bias voltage is removed) decrease the amplification by one step (12 [dB])
  • If the signal peak is lower than 3.5 [V] (or 0.5 [V] if bias voltage is removed) increase the amplification by one step (12 [dB])

Note that the dynamic mode is an alternative output (AC) with a bias voltage (DC) of 3 [V].
