Page 7: Introduction To Minox-I
Minox-i Oxygen Transmitter User Manual Introduction to Minox-i This manual is applicable to Minox-i oxygen transmitter with electrochemical (EC) or solid-state (S-S) sensors; and KF40 flange, flow-through or 2” tri-clamp process connections. Overview ATEX, IECEx and UKCA certified, the Minox i is an intrinsically safe (I.S), 2-wire, loop-powered oxygen transmitter with a 4...20 mA output. -
Page 8: Components
Minox-i Oxygen Transmitter User Manual Components The Minox-i oxygen transmitter consists of an oxygen sensor and inbuilt microprocessor. They are encased in stainless steel, with a process connection on the removable housing and an electrical signal connector on the main housing. The sensor is replaceable and can be accessed via the removable housing, as shown in Figure Removable housing... -
Page 9: Solid-State (S-S)
Minox-i Oxygen Transmitter User Manual 1.3.3 Solid-state (S-S) The Minox-i S-S sensor is not gas-dependent or specific, and offers a robust measurement capability on process gas streams or in containment environments. It can operate with or without sample flow, making it ideal for in-situ monitoring, and it is not orientation-specific. With the tri-clamp and KF40 process connections, the Minox-i can be mounted on a T-piece of pipe- line or on the vertical panel of a containment system without concern. -

Page 14: Install Your Sensor
Minox-i Oxygen Transmitter User Manual The Minox-i oxygen transmitter operates using a 2-wire industry-standard 4...20 mA loop-powered supply which you must provide. Once the Minox-i is connected to your process, it is ready to be connected to your power supply. To do this: Align the pins in the Minox-i electrical signal connector with the M12 mating connector on the cable. -
Page 15: Calibration
Minox-i Oxygen Transmitter User Manual Calibration NOTE: Calibration should be carried out by an appropriately trained or suitably qualified person. The oxygen sensor output will decrease over time, and periodic calibration will be required. This is a non-intrusive procedure, achieved by using the MagTip one-touch calibration tool included with your Minox-i. - Page 16 Minox-i Oxygen Transmitter User Manual NOTE: The pressure flow should replicate that applied to the Minox-i during normal operation. This will ensure calibration is accurate, and avoid over-pressurizing the oxygen sensor. To customer control system interface Typical in-situ pipeline calibration application Cylinder oxygen or ambient air (20.9 %) ²...

Minox-i Oxygen Transmitter User Manual Air calibration The following method of air calibration should only be performed on a Minox-i %. Figure 9. Minox-i indicator LED Unfasten and remove the Minox-i from your process, and leave it in an ambient air environment. Ensure the environment has normal oxygen concentration, an independent portable oxygen ana- lyzer can be used to check this. -
Page 18: Maintenance
Minox-i Oxygen Transmitter User Manual Maintenance General To maintain performance, the sensor in Minox-i will require replacement. Please check the Technical Specifications for frequency. During sensor replacement, it is recommended that light cleaning of the external housing is carried out, as well as the checks outlined in this section. Never use chemical cleaning agents or high pressure water or steam to clean the equipment. -
