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 SPXCDALMB2M 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 SPXCDALMB2M aluminium or stainless?
- SPXCDALMB2M enclosure is LM25 epoxy-coated aluminium. Aluminium is lighter; 316SS for salt/CIP. Sibling SPXCDASMB2M.
- Is the safety function on SPXCDALMB2M the relays or 4–20 mA?
- On SPXCDALMB2M the only EN performance safety function is 4–20 mA. Relays and Modbus are not SIL/performance-certified.
- How do I calibrate SPXCDALMB2M?
- Zero/span SPXCDALMB2M on the transmitter with certified gas and cap S3KCAL. Recalibrate after cartridge swap.
- What sensor life should I plan for SPXCDALMB2M?
- Plan SPXCDALMB2M sensor life by principle: IR ~5 years. Replace the cartridge and recalibrate.
- Can I retap SPXCDALMB2M from M20 to NPT?
- No. SPXCDALMB2M flameproof entries are machined 2 × M20. Order the matching P/N for the other thread.
