Selection of probes based on Pt100/Pt1000, thermistors or thermocouples Platinum Temperature Sensor (Pt100/Pt1000) Platinum measuring resistors incorporate a Pt100 or Pt1000 sensor with 1/3 DIN accuracy. They are available in two-wire and also four-wire technique when power resistance needs to be compensated for. Platinum sensors can operate within the range of -50°C...+400°C while still maintaining high accuracy and long-term stability. Thermocouples Thermocouples are suitable for a broad temperature range between -25°C and +1100°C. They feature a fast response time and can be used for applications in hard to reach spaces or for rough, industrial applications. Thermistors Thermistors are sensors based on metal oxide semiconductors which produce a much larger change in signal when temperatur changes occur. Their operating range is -50°C...+150°C. They come in miniaturized design, helping their fast response time. Due to the thermistor's high resistance the effect of power...

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.
