DRIESEN + KERN GMBH - Your Measurement & Data Logger Specialist

The models P-Log3020 PA (=absolute pressure) and P-Log3020 PR (=gauge pressure) are data loggers capable of measuring water level with an accuracy of a few millimeters and also water temperature. Highlights of these data loggers are their high resolution as well as large memory. They offer a high long-term stability and provide reliable measurements over many years without a battery change thanks to an optimised energy consumption.

SHT75DK Digital, High Precision Sensor for Humidity and Temperature The digital humidity sensor SHT75DK comes fully calibrated and is easy to install thanks to its pin-type package (for 1.27mm sockets). Individual calibration and digital output make it a fully exchangeable option and also spare you the painful and intricate recalibration after changing it. Its sensor head is connected to the pins only through a thin bridge isolating it thermally which further improves its response time. A sealing ring in front of the pins protects against humidity and corrosion. The sensor element can completely seal openings with a diameter of 7mm.

The DKRF300 and DKRF300-0835 probes are based on the combined humidity and temperature Sensor SHT75 by Sensirion. Their filter protects the sensor against splash water and dust. Being of robust design the stainless steel probe body offers additional protection. This humidity/temperature sensor provides the digital two-wire signal by Sensirion (see SHT75DK data sheet for further information).

Based on the combined humidity and temperature sensor SHT21 by Sensirion we offer you the DKRF310XXS probe. The sensor is either integrated into a miniaturized stainless steel sleeve (d=4mm, l=20mm) or can be delivered as a tube probe. It provides an I2C output signal.

The humidity sensor DKRF4001 comes with two analog outputs. Its micro-module is specifically designed for OEM applications. High accuracy as well as excellent long-term stability are among its features. The calibrated, linear outputs offered are 0..1/0..5/0..10VDC. The sensor modules can perform measurements at 0...100%RH and between -20...+80C. With the right configuration measurement applications which demand higher temperatures can be performed.

The micro-module DKRF4002 is designed for humidity measurements withing the range of 0...10%. Its humidity sensor offers high accuracy and excellent long-term stability and was specifically developed for OEM applications which require a RS232 interface Signals both for temperature and relative humidity can be output through the serial interface. Two models differing in measuring accuracy are available: DKRF4002 with +/-3.5RH and DKRF4002-P with +/-2%RH.

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...

The DKRF470 Series of transducers was designed for sophisticated measurement applications (humidity and temperature) such as in process automation, HVAC in public swimming pools or greenhouses. Based on the latest capacitive sensor technology by Sensirion (CMOSens) the devices provide a precise yet affordable solution for a variety of potential measuring tasks. They are extremely resitant to dust as well as most chemicals and provide high accuracy and reliability (+/-1.8%RH / +/-0.3°C). The sensor head is available as a spare part with or without a certificate of calibration which allows you to change it on-site.

The DKRF415 humidity/temperature probe was specifically designed to work in areas with elevated pressure levels and in vacuum. The probe's operating range is 0...100% RH and it tolerates temporary condensation. It delivers accurate readings (up to +/-1.8RH / +/-0.3°C) even when working in compressed air up to 2 bar.

Reasonably Priced and Precise The humidity / temperature probe DKRF400 was designed for applications where cost-efficient, flexible solutions and high accuracy are essential. The probe can operate within a range of 0...100%RH and offers an accuracy of +/-1.8%RH between 20...80%RH. Even in rough conditions beyond this range it provides accurate readings (see data sheet). Regardin temperature, the probe's accuracy is +/-0.3°C at 25°C. Two separate analog outputs each provide a linear signal of 0..1/0..5/0..10VDC or 4..20mA with an optional module. Miniaturized Design The DKRF400 probe distinguishes itself through its miniaturized and robust design. Its small dimensions (d=8mm, l=100mm) permit its use in a variety of applications The housing is made of stainless steel and can be equipped with cables of different sizes. Low Maintenance The probe features the miniaturized sensor SHT75DK which can be delivered as a fully calibrated spare part. The plug-in sensor can be exchanged...
