Relative humidity sensor
Cognito Quam Electrotechnologies Ltd

Our humidity/moisture sensors address the problem of measuring humidity in-line production and without interfering chemically, physically or mechanically with the processes taking place.

The features of this technology are:

* Being based on the capacitive principle, our sensor is robust, has no moving parts and is chemically, physically and mechanically inert,
* Detecting capacitance does not react in any way with the monitored process and the sensor can be of any physical shape,
* Detects absolute quantities of water, so the monitored mass can be in any substance, form or phase.

The special CSNS Sensor and Controller interfaces to the sensor and combines sensing in remote locations with local control functions. The CSNS Sensor and Controller features the following:

* Galvanically isolated sensor capacitance measurement,
* Two configurable multifunction analog ports for voltage, potentiometer or 2-wire/3-wire Pt100 temperature element input,
* Two configurable galvanically isolated 24 VDC universal connection single bit inputs,
* Two configurable galvanically isolated single bit outputs,
* Dual standard serial communication port: EIA(RS)232 and EIA(RS)485.
* Dual 230/115 VAC power supply.
* Aluminium cast enclosure protected to IP65.
* Simple, self-contained, unattended operation by non-specialist personnel,
* Fully programmable, locally or via the network connection, parameters and functions for each port, input and output,
* Five point calibration table to convert the internal humidity reading to user units,
* Compensation functions for temperature dependencies, series capacitance and similar effects, and
* Complete integration within supervisory systems.
