These All ZR800 Oxygen Analysers utilise The oxygen detection cell is a high purity, high Electronics characteristics are found in Systech’s process precision Zirconia Oxide sensors for density, stabilised zirconia ceramic. The sensor oxygen analysers. The ZR800 Series Oxygen accurate detection of oxygen. produces a voltage signal relative to the oxygen Solder Powder Production Analysers are capable of measuring from 0.1ppm concentration of the sample gas stream. The cell’s Semiconductor Furnaces up to 100% oxygen in most industrial gas streams. logarithmic output is converted and linearised by a With a response time and accuracy unparalleled in high speed microprocessor to provide a direct digital Gas Quality the industry, the ZR800 has found wide ZR810 readout on the instrument’s LED display. acceptance in the electronics, semiconductor, food processing, and gas manufacturing industries. Metals These microprocessor controlled instruments have Zirconia Oxide Sensor Theory Heat Treating / Annealing user-friendly menu driven software to customise the analyser to meet your requirements. The The conventional zirconium oxide cell consists of a Steel Production ZR800 series is specifically designed to provide zirconium oxide ceramic tube plated with porous Pure Metal Production ultra fast oxygen analysis and performance you platinum electrodes on its inner and outer surfaces. can count on. As the sensor is heated above 600°C, it becomes permeable to oxygen ions (O - 2 ) with vacancies in its Pharmaceutical ZR820 crystal lattice structure permitting their mobility. Cabinetry & Mounting Because of this, the sensor becomes an oxygen Inert Packaging Three different configurations to match your needs. ion-conducting electrolyte. Fermentation Panel or bench mount The electrodes provide a catalytic surface for the Vessel Blanketing NEMA 4X / IP66 waterproof and weatherproof change in oxygen molecules, O2, to oxygen ions, 19 in. rack mount and oxygen ions to oxygen molecules. Oxygen molecules on the high concentration reference gas Process side of the cell gain electrons to become ions which Operator Interface /Diagnostics Ceramics enter the electrolyte. Simultaneously, at the inner electrode, oxygen ions lose electrons and become Contact Lens Manufacturing User-friendly menu released from the surface as oxygen molecules. Read-only mode available Food Packaging ZR830 Diagnostic capabilities When the oxygen concentration differs on each side Glass/Fibre Optics Fault alarms of the sensor, oxygen ions migrate from the high Inert Gas Welding concentration side to the low concentration side. This ion flow creates an electronic imbalance Lamp Manufacturing Sampling Systems resulting in a DC voltage across the electrodes. This Solar Cell Manufacturing voltage is a function of the sensor temperature and Bypass flowmeter the ratio of oxygen partial pressures (concentrations) Pressure regulator on each side of the sensor. General Sample pump Flow alarm Gas Production Auto Calibration The relationship between the oxygen Where: R = gas constant concentration of the unknown gas, Controlled Environments Cartridge Filter Kit F = Faraday’s constant the oxygen concentration of the O2 Ref. gas = partial pressure of oxygen in air Glove Boxes reference gas (typically air which is O2 Sample = partial pressure of oxygen in 20.9% oxygen by volume), the Oxygen Deficiency Outputs & Alarm Options sample gas temperature, the voltage output, and T = absolute temperature of Research & Development the cell constant is defined by the For charting, process control, or remote Zirconia sensor Nernst Equation which states: monitoring RS232 / 485 Stabilized ZrO2 Platinum Analogue outputs electrolyte electrodes RT O2 Ref. gas Sample gas High / low alarms E(mV) = log Fault alarms 4F O2 Sample Flow alarm DC Voltage output Ambient air reference gas ZR800 Process Oxygen Analysers ZR810 ZR820 ZR830 Bench/Panel Mount IP66/NEMA 4X Rack Mount 4U - 19 inch 190H x 237W x 410D (mm) Wall Mount/Weatherproof Houses 1 or 2 Analysers 7.9 kg 460H x 380W x 160D (mm) 178H x 484W x 410D (mm) 15.5kg 9.7kg (single unit) Technical Specifications Range Autoranging from 0.1ppm to 100% Accuracy 10% -100% 0.2% absolute (max 2% of reading) and ±1 on the last digit shown 1% -9.99% 0.02% absolute (max 2% of reading) and ±1 on the last digit shown. 100ppm - 0.999% max 1% of reading and ±1 on the last digit shown 0.1ppm - 100 ppm max 2% of reading and ±1 on the last digit shown Response Time 90% of step change within 5 seconds Repeatability 0.2% of measured value Measuring Cell Type Stabilised zirconia sensor Operating Conditions Sample Inlet Pressure 0.25 to 4 Barg Sample Flow Rate Approximately 150cc/min Sample Temperature -5 to 50°C Ambient Temperature -5 to 50°C Sample Humidity 0-99% non-condensing Sample Connections 1/8” OD compression fitting Communications USB/RS232/RS485 Unsuitable Gases H2S, Ammonia, Corrosive gases, Hydrocarbons, Combustibles, Hydrogen, Carbon Monoxide, NO2, Halogens, Halogenated Hydrocarbons, Sulphur containing compounds, Lead containing compounds.
