Why this principle
Fixed-point leak monitoring into a controller/ESD on 4–20 mA.
Typical applications
Fixed-point leak monitoring into a controller/ESD on 4–20 mA. Magnetic bump test without a hot-work permit.

Wall-mount SPXCDALMPX 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
- Is the safety function on SPXCDALMPX the relays or 4–20 mA?
- On SPXCDALMPX the only EN performance safety function is 4–20 mA. Relays and Modbus are not SIL/performance-certified.
- Can I retap SPXCDALMPX from M20 to NPT?
- No. SPXCDALMPX flameproof entries are machined 2 × M20. Order the matching P/N for the other thread.
- Does SPXCDALMPX need weather protection?
- Outdoors, fit SPXCDWP weather protection on SPXCDALMPX with the sinter down.
- Who supplies SPXCDALMPX and what should I quote?
- Supplied by authorized Honeywell distributor Beijing Dongfang Haitai (GZion). Quote full P/N SPXCDALMPX. Not in stock — orders accepted; lead time approx. 10 weeks. Quote full P/N SPXCDALMPX.
- What gas and range does SPXCDALMPX cover?
- SPXCDALMPX measures propane at default 0-100%LEL (user window 20.0–100.0%LEL). Principle: Infrared (dual-beam).
- Can I fit a different-gas cartridge on SPXCDALMPX?
- XCD auto-recognises the same family only. Do not mix an O₂ cell onto a flammable/toxic SPXCDALMPX transmitter.
- Can I hot-swap SPXCDALMPX live?
- Do not hot-swap live. De-energise first; live swap damages pins and the flameproof joint.
