Humidity sensors - Import export

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.

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).

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 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.

Having a very low energy consumption the humidity loggers can be used for up to a few years without any battery change. While DCXP-RH8 is a 16 channel datalogger for humidity and temperature, whcih means up to 8 combined probes can be connected, the DCXP-RH16 has twice as much chenels ready to connect up to 16 combined humidity and temperature probes. For your application Driesen + Kern GmbH offers a range of probes: miniature probes (D=4mm, L=20mm) , Probes for pressurised pipes (DKRF374), Standard probes D=8mm und L=40/100mm (DKRF300) and many more.

The DK8040 is a robust and flexible stationary data logger for measuring climate parameters. The inputs can be configured for voltage signals and special sensors such as PT100 temperature probes, soil moisture and humidity sensors or condensation detectors. In additon, connection of sensors for rainfall and solar radiation is also possible. The logger comes in a robust, IP65 splash water protected housing which allows for measurements even under rough conditions, e. g. in the rain or snowfall.

The DKRF417 humidity and temperature transducer ist the best choice for measurements at very high pressure levels. It is pressure-resistant up to 30 bar. Thanks to its small dimensions and M8 thread it is very well suited for applications within compressed air lines with small diameter. The probe’s operating range is 0...100% RH and it tolerates temporary condensation. It delivers highly accurate readings of up to 1.8%RH / 0.3°C. The DKRF417 humidity/temperature probe provides reliable readings even in challenging environmental conditions: · Compressed Air Systems · Engine Test Benches · Industrial Automation Technology We offer the compact, pressure-resistant transducer DKRF417 for relative humidity and temperature as well as the pressure-resistant humidity sensor EXT-D of the DKRF470 Series and the humidity and temperature Probe DKRF400.

Multi-Channel Data Logger DK650 “rugged-Visual” with Internal and External Sensors The “rugged-Visual” series by Driesen+Kern GmbH sets standards for customizable data acquisition. In addition to ist five integrated sensors for humidity, temperature, barometric pressure, light, and differential pressure the device offers three input slots for external probes or analogue signals. All three slots can be completely configured by the user - hence you don’t need to tie yourself down beforehand, but rather you can customize the “rugged-Visual” according to your measuring task. The robust logger stores up to 4 million readings and its freely selectable sampling interval reaches from 32 Hz to 24 hours. Using modern low power technologies the device can perform continuous operation for up to 4 years with only one standard lithium battery. An internal back up system provides several days of continued logging in case the battery is completely drained. Of course, you can always replace the...

Micro Sensor for Humidity and Temperature The Micro Sensor DKRF410 is available as one of two models which are especially suitable for humidity and temperature measurements in areas difficult to access such as insulation, concrete walls, floor screed, product and packaging tests. The DKRF410 probe has a range of 0...100% RH and offers an accuracy of up to 2% RH. At the same time temperature measurements with a range of -40...+80°C can be undertaken. Two separate analogue outputs each provide a linear signal f 0...1V / 0...5V or 0...10V. A passive output signal for temperature (PT100) can also be provided. If you require a 4-20 mA output signal the DKRF 473 industrial transmitter can be used with the -XS and -XXS probe. The DKRF410 is also available with digital outputs (RS232, USB, RS485).

The Driesen + Kern GmbH DKRF425 probe series for flush-mounting is designed for controls and automation such as in HVAC. The sensors measure tempeature, humidity, CO2 concentration and light intensity. They fit into standard flush-mounted boxes and are compatible to switch product ranges of several manufacturers. This makes them well suited for integration in existing building concepts.
