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 SPXCDULNHX through the one-piece plate with M8 bolts. Entries 2 × ¾″ NPT — glands must match. Land 4–20 mA as three-wire. Magnetic wand calibration stays non-intrusive.
FAQ
- What sensor life should I plan for SPXCDULNHX?
- Plan SPXCDULNHX sensor life by principle: electrochemical/O₂ ≥24 months. Replace the cartridge and recalibrate.
- Can I magnetically calibrate SPXCDULNHX without opening the lid?
- Use the S3KCAL wand on the SPXCDULNHX lid calibration pad — non-intrusive. Recalibrate after a swap.
- What temperature rating does SPXCDULNHX have?
- SPXCDULNHX certified −40 to +65 °C (T6); some T-class to +75 °C.
- How much does SPXCDULNHX weigh?
- SPXCDULNHX approx. 1.7 kg (trust the nameplate).
- How do I calibrate SPXCDULNHX?
- Zero/span SPXCDULNHX on the transmitter with certified gas and cap S3KCAL. Recalibrate after cartridge swap.
- Does SPXCDULNHX provide 4–20 mA?
- SPXCDULNHX outputs 4–20 mA (source/sink). 4–20 mA is the only EN performance safety function.
- Which cartridge or transmitter pairs with SPXCDULNHX?
- Same gas code. Cartridge SPXCDXSHXSS; transmitter needs the same family.
- Does SPXCDULNHX have relays?
- SPXCDULNHX has three relays 5 A @ 250 VAC. Relays are not the EN performance safety function.
- Is the safety function on SPXCDULNHX the relays or 4–20 mA?
- On SPXCDULNHX the only EN performance safety function is 4–20 mA. Relays and Modbus are not SIL/performance-certified.
