DD103 DrDAQ Oxygen Sensor User’s Guide DO091-2
DD103 DrDAQ Oxygen Sensor User Guide 1 Pico Technology Introduction The DD103 Oxygen Sensor is used to measure the percentage of oxygen in a gas. The sensor plugs into the external sensor sockets of DrDAQ using the supplied cable. 2 3 Specification Sensor type Galvanic Cell (lead-oxygen with weak acid electrolyte) Input range 0 - 100% oxygen Accuracy (calibrated) ±3.0% over operating conditions range Response times < 15 seconds for 90% response < 25 seconds for 97% response Max.
Pico Technology 4 DD103 DrDAQ Oxygen Sensor User Guide Calibrating the oxygen sensor Both PicoLog and PicoScope provide the facility to enter look-up tables. These instructions will concentrate on doing so in PicoLog (for instructions on Custom Ranges in PicoScope, see the PicoScope manual from the Help menu within the application). This is the information known so far: Raw values (%) 0 Calibrated values known to be true (%) 0 20.
DD103 DrDAQ Oxygen Sensor User Guide 5 Pico Technology Looking after the oxygen sensor Ensure that the storage temperature and humidity ranges in the specification are not exceeded. The sensor is not designed for use in liquids and using it in this way will damage the sensor. The sensor has a lifetime of >1,200,000 O2 % hrs; in air at sea level the sensor will operate effectively for over 4 years (this will decrease if the sensor is exposed to high oxygen concentrations for prolonged periods).
