Sensors for Water Quality Parameters pH/Temperature pH-Sense330 Conductivity/Temperature µS-Sense340 O2 Saturation/Temperature O2-Sense350 The Sense300 Series by Driesen+Kern GmbH consists of three models for different water quality parameters. Each sensor model also measures temperature thus ensuring precise and temperature compensated readings. Electronic circuits are entirely integrated into the stainless steel housing making it compact and entirely submersible. Of course, it can also be installed in the process assembly. The user himself can perform calibration and exchange the electrode on each model. Devices are available with analog, digital and switching output. Analog outputs are 0-1V/0-10V or 4..20mA in thre-wire or as 4-20mA current loop. Optionally, the sensors can be fitted with a relay output whose switching value will be factory-set, but can later be changed with the programming kit.

The DKRF670 Series by Driesen + Kern GmbH was developed for measuring humidity related parameters especially in industrial applications. All models have a relative humidity measuring range of 0...100%RH and can also measure temperature. Calculated variables such as absolute humidity (g/m3), dew point (°C), mixing ratio (g/kg) are optionally available. The series' measurements are very accurate for humidity (up to +/-1.8%RH) as well as temperature (up to +/-0.1K). An ISO9001 traceable certificate is included in delivery. Three analog output signals are provided for a customer-specific combination of the chosen parameters (relative humidity, temperature, absolute humidity, mixing ratio, dew point). Analog signals can be 0..1/0..5/0..10VDC, and also 4..20mA three-wire. The transducer's electronic circuits are integrated in a robust aluminium housing that is protected against dust and splash water according to protection class IP65, which makes the devices well suited for use in wet...
