Product Description
Overview：
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 96% O2 for oxygen concentrators.
The flexibility is further enhanced by process connection multiple output options.
Features：
» Zirconia or electrochemical sensor technology options
» Measurement range: 0 to 10ppm up to 0 to 96% O2
» RS 485 modbus protocol
» 24VDC power supply
» KF40 Flange, Flowthrough and Flow Orifice process connection options available
» Combined Sensor & Electronics allows for ease of integration.
» Lightweight and robust (< 0.3Kgs)
Applications：
» Gas generation (oxygen / nitrogen)
» Additive manufacturing
» Glove box purge and leak detection
» Industrial gas applications
