FAQ
A1: Yes, the transmitter supports multiple ranges from single-digit ppm to 25% oxygen, allowing use across many gas-analysis processes.
Q2: What type of signal does the O2X1 provide?
A2: It provides a two-wire 4–20 mA analog output that connects easily to PLC, DCS, or data loggers.
Q3: Is the O2X1 suitable for hazardous environments?
A3: Yes. Intrinsically safe versions allow installation in hazardous or explosive atmospheres.
Q4: How fast does the sensor respond to oxygen changes?
A4: The transmitter typically reaches 90% of a concentration change in less than 15 seconds.
Q5: How often must the sensor be replaced?
A5: Replacement frequency depends on gas composition and operating hours, but the galvanic design typically provides long service life with low maintenance.
Q6: Can the O2X1 operate outdoors?
A6: Yes. Its weather-resistant stainless-steel or Delrin enclosure makes it suitable for outdoor installations.
