Oxygen Transmitter The SenzTx is a compact and robust O2 transmitter that utilises zirconia or electrochemical technology to give a reliable measurement of oxygen concentration. The zirconia sensor offers fast response time and a long service life with virtually no drift, whilst the electrochemical sensor allows measurement in background gases containing hydrocarbons. The minimum output range of 0 to 10ppm is ideal for nitrogen generation or glove box monitoring. The SenzTx transmitter can also be supplied with measuring ranges up to 0 to 100% O2 for oxygen concentrators. The flexibility is further enhanced by process connection multiple output options. » Gas generation (oxygen / nitrogen) » Zirconia or electrochemical sensor technology options » Additive manufacturing » Glove box purge and leak detection » Industrial gas applications » Measurement range: 0 to 10ppm up to 0 to 100% O2 » Analogue output: 4 to 20mA » Modbus 485 » 24VDC power supply » M12 electrical connection » Process connection: KF40 Flange or Flowthrough base » Combined Sensor & Electronics allows for ease of integration. » Fast reponse from ambient air to low PPM oxygen measurement Issue No. STX01_

Oxygen Transmitter Proven sensor technology With a choice of either zirconia or electrochemical sensor technology the SenzTx offers reliability, accuracy and flexibility. Both technologies have a broad measurement capability allowing the user to measure from selected ranges from 1ppm to 100% oxygen. Zirconia sensor The Ntron zirconia oxygen sensor is a nondepleting zirconia solid electrolyte sensor. A small capillary on the sensor controls the diffusion of oxygen into the sensor. When heated to over 400°C oxygen is electronically reduced causing current flow through the zirconia electrolyte....
