Frequently Asked Questions (FAQ)

• Can I use this with a non-HART system?
  Yes, the 4-20mA analog output works without HART.
• How often should I calibrate?
  Every 3 to 6 months, depending on the environment.
• Is the sensor field-replaceable?
  Yes, you can swap it quickly without tools.
• What is the maximum cable length?
  Up to 1000 meters with proper shielding.
• Does it work in high humidity?
  Yes, IP66/IP67 protects against moisture.
• Which gas does it detect?
  Specifically methane (0-100%LEL / 0-5%v/v).
• Can I use it for other hydrocarbons?
  Only with a different MPD sensor head.

Experience & Selection Guide

• For outdoor installations, choose the 316SS option for corrosion resistance.
• If you need remote monitoring, use the HART® digital signal.
• For fast response, position the sensor close to potential leak points.
• Always verify the gas type and range before ordering.
• Contact our support for custom sensor configurations.
