RMP / Recycling & ΔP pairs
Melt Pressure Sensors for Recycling & Abrasive Compounds
Specify the resin, abrasive loading and chemistry before choosing diaphragm alloy and coating. Review upstream / downstream sensing as a matched pair for screen-changer monitoring.
Confirm before ordering
- Request evidence for the proposed alloy, coating and weld integrity. A material name alone does not prove installed service life.
- Match the ranges, temperature limits, pressure references, sampling and zero checks of both sensors.
- A calculated pressure difference is not a certified clogging alarm or pressure-relief design.
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.
Match the diaphragm to the actual compound
| Selection | Configuration request | Confirm before ordering |
|---|---|---|
| Abrasive fillers / contaminants | Request Inconel 718 and reviewed coating options | Provide filler type, loading, particle size, temperature and cleaning method |
| Corrosive compounds / degradation products | Request a chemistry-specific alloy review | Supply resin, contaminants, temperature and chemical compatibility evidence |
| Screen-changer pair | Same pressure reference, ranges and thermal conditions | Define measurement points, sampling, zero drift and alarm design separately |
Inconel, Hastelloy and coating names are material requests, not guarantees of service life or chemical compatibility. The process engineer defines alarm and machine protection limits.
Compare a pressure pair
Both readings must use the same units, pressure reference and synchronized conditions. This tool does not set filter alarms, machine trips or relief ratings.
