RMP / Mercury-free probes
Mercury-Free NaK & Fluid-Free Melt Pressure Sensors
Review mercury-free fill options for high-temperature polymer processing. Select the fill and diaphragm together using the process temperature and contamination requirements.
Confirm before ordering
- Up to 400°C is a requested process-temperature envelope; electronics have a separate ambient limit.
- Food and medical applications require configuration-specific declarations and process approval.
- NaK is chemically reactive. A mercury-free fill is not a claim of harmless leakage.
Pressure & mounting choices
Specify full scale in PSI or bar: 1,500 PSI ≈ 103.4 bar; 3,000 PSI ≈ 206.8 bar; 5,000 PSI ≈ 344.7 bar; 10,000 PSI ≈ 689.5 bar. Nominal 100 / 200 / 350 / 700 bar ranges are separate specifications.
Review 1/2″–20 UNF, M14 × 1.5, M18 × 1.5 or M22 × 1.5 against the full bore drawing. The thread alone does not define compatibility.
Select fill and sensing architecture separately
| Selection | Configuration request | Confirm before ordering |
|---|---|---|
| NaK-filled / RMP-NAK | Mercury-free liquid transmission request | Review fill SDS, diaphragm, pressure and hot-zone / ambient limits |
| Fluid-free / RMP-DRY | No pressure-transmission fill request | Confirm sensing method, dynamic behavior, wetted materials and cleaning limits |
| Oil-filled option | Use-specific temperature and material review | Do not apply another fill family’s maximum temperature |
Industry products use different thermal architectures. No competitor temperature, diaphragm-thickness ratio or conformity claim is transferred to an RMP family.
