Campini Corel TY 87H Pressure Transducer
Industrial/HVAC pressure transducer family; original manufacturer lists TY 87H among pressure controls.
Original manufacturer: Campini Corel, Italy.

TY 87H is listed by the manufacturer as a pressure transducer, not a mechanical switching pressurestat. Confirm the electrical transfer function, connector, calibrated range and installation approval against the ordered device documentation.
TY 87H — manufacturer-confirmed pressure and environmental specifications
Campini Corel lists TY 87H as a pressure transducer intended for wall-mounted boilers and pellet stoves. It should not be presented as a simple snap-action pressure switch without evidence of an actual relay contact.
| Original maker parameter | Published TY 87H value | Engineering interpretation |
|---|---|---|
| Orderable pressure span choices | 0–3 / 0–4 / 0–5 / 0–5.5 bar | Choose full scale by exact ordered suffix, not a generic 5.5-bar assumption. |
| Rupture pressure | >30 bar | Destructive rupture limit is not allowed continuous working pressure or an independent pressure safety rating. |
| Current consumption | <10 mA | Source does not give a universal operating supply or output type; obtain the exact variant drawing / test documentation. |
| Ingress protection | IP00 | Do not install as a weatherproof or washdown-rated field sensor without a separately engineered protective enclosure. |
| Working temperature | −15…+90°C | Confirm pressure-medium compatibility, mounting thermal gradients and long-term stability for boiler hydraulics. |
| Electromagnetic standards | EN 55032 and EN 61000-4-2/-3/-4/-6/-8 listed | These relate to EMC design; they do not prove ATEX/IECEx or pressure-equipment certification. |
Integration and replacement checklist
Document media, gasket/seal, pressure port size, calibrated full-scale variant and host signal mapping. Verify whether the original unit is used for continuous measurement or a controller-derived cutout; do not conflate transducer pressure measurement with an independently rated overpressure relief or limit switch. The manufacturer’s public page does not provide a model-independent analogue transfer curve; that parameter remains pending OEM documentation.
