Why this principle
A poison-resistant pellistor sees the heat of combustion and therefore works on a wide hydrocarbon mix, including species IR filters miss. It is not a toxic detector.
Typical applications
Pump rooms, filling gantries and compressor packages still standardise on catalytic LEL.
Installation
Wall-mount SPXCDALMFX through the one-piece plate with M8 bolts. Entries 2 × M20 — glands must match. Land 4–20 mA as three-wire. Magnetic wand calibration stays non-intrusive.
FAQ
- Which accessories go with SPXCDALMFX?

- Does SPXCDALMFX need weather protection?
- Outdoors, fit SPXCDWP weather protection on SPXCDALMFX with the sinter down.
- Can I magnetically calibrate SPXCDALMFX without opening the lid?
- Use the S3KCAL wand on the SPXCDALMFX lid calibration pad — non-intrusive. Recalibrate after a swap.
- Can I hot-swap SPXCDALMFX live?
- Do not hot-swap live. De-energise first; live swap damages pins and the flameproof joint.
- Does SPXCDALMFX use M20 or NPT entries?
- SPXCDALMFX entries are 2 × M20. Do not retap in the field; order the matching P/N.
- Is the safety function on SPXCDALMFX the relays or 4–20 mA?
- On SPXCDALMFX the only EN performance safety function is 4–20 mA. Relays and Modbus are not SIL/performance-certified.
- How do I calibrate SPXCDALMFX?
- Zero/span SPXCDALMFX on the transmitter with certified gas and cap S3KCAL. Recalibrate after cartridge swap.
- Does SPXCDALMFX have relays?
- SPXCDALMFX has three relays 5 A @ 250 VAC. Relays are not the EN performance safety function.
