The JUMO digiLine O-DO S10 is a modern, intelligent sensor for measuring dissolved oxygen. The measurement is based on the optical principle of luminescence quenching according to ASTM D888-05. This offers users numerous advantages: No electrolyte replacement required No polarization voltage necessary No minimum flow required Longer calibration intervals thanks to low drift behavior Long-term stable and reliable measurement results Temperature compensation is performed automatically, so that the measured value is always output temperature-compensated. In addition, the sensor can also correct the measured value with regard to air pressure and salinity (using external sensors). The JUMO digiLine O-DO S10 has two interfaces for transferring the measured values to higher-level systems or automation solutions: digitally via an RS485 interface with Modbus RTU protocol or analogically via a 4...20 mA two-wire signal. Configuration, parameterization, and calibration data are stored in the sensor's electronics. Sensor-specific information and measuring point identifiers can also be stored there and read out as needed. In addition, the sensor offers a logbook that documents the last ten successful calibrations, providing an overview of the calibration history. To support operational safety, the sensor is equipped with a self-diagnostic function that issues warnings or error messages in the event of malfunctions. The sensor features a slim, robust design. The sensor cap can be easily replaced when worn. The sensor body is made of durable PVC and is therefore suitable for applications in fresh and salt water. A permanently attached cable with a 5-pin M12 connector ensures quick and easy connection to measuring or automation devices. The sensor offers two connection options for installation: an Rp 1 thread directly on the sensor shaft or, alternatively, an optionally available mounting kit with a G 1 thread.

Two versions with cell constants K = 0.1 or 1.0 are available. Versions with the common thread sizes G 3/4" or G 1" or a plug-in version are available for installation. The plug-in version is used, for example, with the matching PVC tees in nominal sizes DN 25, 32 and 40 and allows the sensor to be quickly dismantled for cleaning or maintenance. The electrical connection is made either via a detachable device plug or via a fixed cable connection. The overall construction and the parts in contact with the medium are physiologically harmless. The electrode material is stainless steel (K = 0.1) or special graphite (K = 1.0). The optionally integrable temperature sensor allows simultaneous recording of the medium temperature for temperature compensation in downstream measuring amplifiers.Stainless steel variant K = 0.1 The sensor has 3 metallic pin electrodes. The two outer pins are electrically connected and form one pole of the 2-electrode conductivity sensor. The counter electrode is the middle stainless steel pin. This design achieves very high measurement precision with low stray fields. A temperature sensor can be integrated in the middle pin. Graphite variant K = 1.0 For physical reasons, special graphite is used as the electrode material for higher conductance values. The two graphite electrodes are completely integrated in the electrode shaft. The optional temperature sensor is located in a stainless steel sleeve that is immersed in the measured medium. Operating principleThe sensors of the 202923 series are 2-electrode conductivity sensors. An AC voltage is applied to them by the transmitter. The current flowing across the liquid and the electrodes is determined by the conductivity of the liquid

This version is intended for measuring points that need to operate reliably not only indoors but also in more demanding environments. With a Pt100 in two-wire configuration, an operating range from -50 to +90 °C and IP65 protection class, this resistance thermometer is particularly suitable for HVAC applications where temperature must be measured in rooms, outdoor environments or air ducts. Technical Data Design: Room, outdoor and duct resistance thermometer Measuring insert: 1 x Pt100 Circuit type: Two-wire configuration Transmitter: none Operating temperature: -50 to +90 °C Protection class: IP65 Tolerance class: Class B Advantages and technical features of the JUMO resistance thermometer high IP65 protection class for more demanding environments suitable for rooms, outdoor areas and air ducts wide operating range from -50 to +90 °C robust design for changing environmental conditions The major advantage of this version lies in its higher protection class. IP65 makes it particularly suitable for installation locations where the housing needs better protection against dust and water jets. This makes it well suited for measuring points exposed to greater daily demands or technically more challenging environments than classic room sensors. A Pt100 sensor in two-wire configuration is used for temperature measurement. This proven version is suitable for many common temperature measurement tasks in HVAC applications. Since no transmitter is integrated, this variant is especially useful where the sensor should be connected directly to a suitable control or evaluation unit. The measuring range from -50 to +90 °C further extends the possible applications. This makes the version suitable not only for typical indoor temperatures but also for cooler or warmer environments as found in outdoor areas or air ducts. Typical Areas of Application room temperature measurement in HVAC applications outdoor temperature measurement temperature monitoring in air ducts heating, ventilation and air conditioning systems

The IP65 protection class makes this version particularly suitable for such requirements. This makes it interesting wherever temperatures need to be measured outside buildings or in more demanding technical environments. Instead of a Pt100, this version uses a Pt1000 sensor in two-wire configuration. This is especially useful when the connected control or evaluation system is designed for Pt1000 or when this sensor version is preferred. Since no transmitter is integrated, the thermometer is particularly suitable for applications where the sensor should be connected directly to a suitable evaluation unit. With a measuring range from -50 to +90 °C, this version covers both low outdoor temperatures and warmer operating conditions. Typical Areas of Application outdoor temperature measurement on buildings HVAC applications heating, ventilation and air conditioning systems technical outdoor environments measuring points with increased protection requirements against dust and water temperature monitoring in weather-exposed environments
