DRIESEN + KERN GMBH - Your Measurement & Data Logger Specialist

The P-Log3021-MMC was specifically developed for applications demanding an increased memory capacity and high sampling rates. The measurement of the water level is carried out based on a piezoresistive pressure sensor and the measurement of the temperature is achieved by a high-precision measuring resistor. Its exceptionally high resolution and accuracy allow for water level and wave movements to be measured accurately to the very last millimetre.

The μS-Log3040 can measure conductivity and temperature in aqueous solutions at the same time. Typical fields of application are monitoring wells, rivers, lakes and sewer tunnels or transportation, e. g. of fish.

The pH-Log3030 is a self-sustaining data logger for unsupervised measurements and logging of pH and temperature. It is perfectly suitable for water quality surveys, e. g. in bodies of water or sewer tunnels, or for monitoring in transportation, e. g. fish or fluids. Once the pH Log3030 has ben set up with a PC it records measurements of the chosen parameters in a freely programmable interval.

The O2-Log3050 is a data logger for dissolved oxygen and temperature. It measures the oxygen saturation level in the water and saves the readings to its internal memory. It also calculates the ppm and mg/l concentration and allows for user-friendly recalibration and changing of its O2 electrode. In combination with its automatic temperature compensation it is best suited for operation in lakes, rivers, in sewage-treatment plants or for monitoring transportation, e. g. of fish.

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.

P-Sense transducers for pressure and temperature can be used both in air and in water or other fluids. Devices come with analog, digital or switching output and can be configured for absolute pressure or gauge pressure measurements. Potential fields of application are water level monitoring or fluid level measurements, e. g. in bodies of water, sewage treatment plants, storage tanks etc. The p-Sense320 probe can be fitted with an RS485 interface instead of an analog output which can optionally be connected to a computer using a RS232 adapter. Connection and data transfer to a PC/notebook can established with the Windows terminal.

Temperature loggers TempLog "rugged" by Driesen+Kern GmbH are extremely robust miniaturized data loggers for temperature. The DK310 incorporates an integrated temperaturesensor whereas the DK311 offers an connector socket for an external temperature sensor. Standard probes are reasonably priced air or surface probes, however a variety of other sensors are optionally available. The housing is made of high quality, shock-proof POM protecting the data logger even under rough conditions. The DK311 is protected against splash water according to IP65 - the DK310 complies even with IP68 and is thus fully submersible.

Data Logger for Temperature Measurements The TempLog TC data loggers by Driesen+Kern GmbH are designed to be used with thermocouples (Types K, T, J, B, E, N, R, S). There are two models available: DK315-TC with a single input channel for a thermocouple, and DFK316-TC with two input channels. Please see our range of thermocouples for surface temperature, air temperature, product temperature which are compatible with the TempLog TC data logger.

The data logger type Dk8040 is a robust and flexible datalogger with up to 10 channels. Each channel can be configured by the user separately for soil moisture, temperature, humidity, condensation as well as several voltage signals. The logger is protected by a robust, IP65 splash water resistant housing enabling applications under tough conditions such as rain or snow.
