Frequently Asked Questions
Q: What is the difference between catalytic and IR sensors?
A: Catalytic sensors measure combustible gases via oxidation heat. IR sensors use infrared absorption. For methane, both work, but catalytic is preferred for many hydrocarbons.
Q: Can I use this detector for oxygen or toxic gases?
A: No, this model is for flammable gases (0-100% LEL). For toxic or oxygen, choose electrochemical or IR versions.
Q: How do I connect this to my existing PLC?
A: Use the 4-20mA output. Or use Modbus for digital integration. HART also provides analog + digital.
Q: Is the sensor field-replaceable?
A: Yes, the catalytic bead sensor is plug-in. No special tools needed. Replacement takes minutes.
Q: What maintenance is required?
A: Annual calibration recommended. Check for sensor drift. Use HART for diagnostics.
