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 SPXCDALMG1 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 SPXCDALMG1 the relays or 4–20 mA?
- On SPXCDALMG1 the only EN performance safety function is 4–20 mA. Relays and Modbus are not SIL/performance-certified.
- Is SPXCDALMG1 ATEX or UL certified?
- SPXCDALMG1 is the ATEX / IECEx / GB scheme. Do not use it as the other system.
- Does SPXCDALMG1 carry a China / GB certificate?
- SPXCDALMG1 literature states GB Ex d IIC T4 (GB3836); no standalone CNEx serial is published here.
- How do I calibrate SPXCDALMG1?
- Zero/span SPXCDALMG1 on the transmitter with certified gas and cap S3KCAL. Recalibrate after cartridge swap.
- How does SPXCDALMG1 differ from SPXCDASMG1?
- SPXCDALMG1 is complete kit (transmitter + cartridge), LM25 epoxy-coated aluminium, 2 × M20, ATEX / IECEx / GB. SPXCDASMG1 is the enclosure/approval/entry sibling.
- Does SPXCDALMG1 provide 4–20 mA?
- SPXCDALMG1 outputs 4–20 mA (source/sink). 4–20 mA is the only EN performance safety function.
- Is SPXCDALMG1 IP66?
- SPXCDALMG1 housing is IP66 (EN 60529). With weather cap and sinter down, IPX6 is kept.
- How is SPXCDALMG1 mounted?
- Wall-mount SPXCDALMG1 on the one-piece plate with M8 bolts; pipe Ø40–80 mm uses SPXCDMTBR, duct SPXCDDMK. Glands must match 2 × M20.
- Can I fit a different-gas cartridge on SPXCDALMG1?
- XCD auto-recognises the same family only. Do not mix an O₂ cell onto a flammable/toxic SPXCDALMG1 transmitter.
