Product catalog summary
Overview: The Oxygen Sensor series 51101 is designed for high-precision measurements in both dissolved and gaseous phases. It is constructed from stainless steel, making it suitable for harsh chemical conditions and high pressures. The sensor offers a measurement range from trace to saturation levels (0.1 ppb to 400 ppm) and is characterized by low maintenance costs and a long life cycle.
Key Features:
  • Low Detection Limits: Capable of detecting oxygen levels below 0.1 ppb (dissolved) or 0.5 ppm (gaseous).
  • Low Maintenance Costs: Features interchangeable anode/electrode and minimal membrane surface contact, reducing maintenance frequency.
  • Easy Calibration: Single point calibration with absolute zero, and EEPROM storage for calibration parameters.
  • Fast Temperature Reading: Integrated temperature sensor in the cathode assembly.
  • CO2 Insensitivity: Configurations insensitive to CO2 during oxygen measurement.
  • Hygienic and Robust: Stainless steel construction with a protective ion cap.
Applications: Suitable for in-line, portable, and package analysis in industries such as beverage production, semiconductor, power-steam, pharmaceutical, and chemical industries.
Technical Specifications:
  • Membrane Utilization: Various membranes according to measuring range.
  • Measuring Range: DO2 from 0.1 ppb to 400 ppm, PO2 from 0 to 10 bars.
  • Flow Rates: Liquid flow rate up to 180 ml/min, gaseous flow rate from 0.005 to 3 l/min.
  • Response Time: Ranges from 7.2 seconds to 2.5 minutes depending on the model.
  • Accuracy: 1% of the measured value or the lowest value, whichever is greater.
  • Temperature and Pressure Ratings: Temperature compensation from -5°C to +60°C, CIP or SIP resistant up to 120°C, pressure rating up to 300 bars.
  • Material: Stainless steel (ANSI 316L), PFA or Tefzel in contact with the sample.
Operating Principle: The sensor is based on a Clark Cell with a semi-permeable membrane, gold and silver electrodes immersed in an electrolytic solution. Oxygen molecules permeate through the membrane, are reduced at the gold cathode, and generate a current proportional to the partial pressure of O2, which is then measured and displayed.

O2 sensor datasheet-1

Oxygen Sensor High precision, simple service, low maintenance • < 0.1 ppb detection limits • Very fast response time • Easy one point air calibration Extremely precise, very robust Oxygen Sensor - series 51101 This electrochemical oxygen sensor is ideal for high-precision measurements in both dissolved and gaseous phases. Built in stainless steel, the sensor is ideal for harsh chemical conditions and high pressures. The measurement range varies from trace to saturation level (0.1 ppb to 400 ppm). Its concept and precise mechanical assembly ensure an optimal performance, a long life cycle and low maintenance costs. Low detection limits detection limits < 0.1 ppb (dissolved) or 0.5 ppm (v/v) gaseous Low maintenance costs • Interchangeable anode/electrode • Minimal membrane surface in contact with the sample reduces maintenance frequency • Large anode surface: the anode is less quickly consumed by the electrochemical reaction and must thus be changed less frequently Easy calibration process • In-line, portable and package analysis • single point calibration due to absolute zero • An Eeprom stores the calibration parameters and avoids recalibration process if the sensor is connected to another Dextens instrument • Dissolved and gaseous applications Fast temperature reading • Beverage production • Semiconductor industry • Power -steam industry • Pharmaceutical and chemical industries • Temperature sensor is integrated in the cathode assembly, enabling a faster temperature reading CO2 insensitive • CO2 insensitive configurations during oxygen measurement Hygienic • Protection cap with special surface treatment Robust • Stainless steel construction: ideal for harsh chemical conditions and high pressures

Oxygen Sensor Dimensions Oxygen Sensor - series 51101 This Oxygen sensor is based on a Clark Cell and consists of a semipermeable membrane, gold and silver electrodes immersed in an electrolytic solution. The membrane houses the electrolyte and acts as the barrier to the sample allowing only small molecular gases to pass through to contact the gold cathode and react. Technical Specifications Membrane Utilization of various membranes according to measuring range Membrane model number A silver guard ring ensures the accuracy of reading by eliminating the effect of any oxygen dissolved in the electrolyte...
