General wiring notes:
•
Use only multi-stranded wire with insulation suitable for application.
•
Two conductor, shielded, 0.5mm² (minimum) cable or twisted pairs is
recommended for field wiring of sensor to electronics.
•
Route all wiring from the analyser away from high power sources and EMI
generating devices.
•
All wires near the analyser enclosure must be as short as possible. Long coiled
wire near the analyser will induce noise.
•
When used in a hazardous area, the OxyTx requires an intrinsically safe (I.S.)
power supply. This can be provided by using proprietary safety barriers.
