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.
Installation
Wall-mount SPXCDALMNX 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
- What gas and range does SPXCDALMNX cover?
- SPXCDALMNX measures nitrogen dioxide at default 10-50ppm (user window 10.0–50.0ppm). Principle: Electrochemical (Surecell™).
- Who supplies SPXCDALMNX and what should I quote?
- Supplied by authorized Honeywell distributor Beijing Dongfang Haitai (GZion). Quote full P/N SPXCDALMNX. In stock. Quote full P/N SPXCDALMNX.
- What is the lead time for SPXCDALMNX?
- In stock. Quote full P/N SPXCDALMNX.
- What temperature rating does SPXCDALMNX have?
- SPXCDALMNX certified −40 to +65 °C (T6); some T-class to +75 °C.
- Does SPXCDALMNX provide 4–20 mA?
- SPXCDALMNX outputs 4–20 mA (source/sink). 4–20 mA is the only EN performance safety function.
- What sensor life should I plan for SPXCDALMNX?
- Plan SPXCDALMNX sensor life by principle: electrochemical/O₂ ≥24 months. Replace the cartridge and recalibrate.
- How does SPXCDALMNX differ from SPXCDASMNX?
- SPXCDALMNX is complete kit (transmitter + cartridge), LM25 epoxy-coated aluminium, 2 × M20, ATEX / IECEx / GB. SPXCDASMNX is the enclosure/approval/entry sibling.
- Can I fit a different-gas cartridge on SPXCDALMNX?
- XCD auto-recognises the same family only. Do not mix an O₂ cell onto a flammable/toxic SPXCDALMNX transmitter.
- Is the safety function on SPXCDALMNX the relays or 4–20 mA?
- On SPXCDALMNX the only EN performance safety function is 4–20 mA. Relays and Modbus are not SIL/performance-certified.
