Selectable configurations vary by ordering code. This model/family listing does not stand for every purchaseable SKU.

BAPI FRP order-specific range

The fixed-range FRP sensing family should be ordered for the correct pressure span and output; status LEDs are diagnostics, not proof of selectable full scale. Verify the actual order code and BMS input type before commissioning. A field-selectable ZPM family is not necessarily a pin-compatible replacement. Confirm static pressure, hose connection and calibration checks for the application.

FRP — factory-selected span/output, not the field-switchable ZPM

The FRP is BAPI’s economy fixed-range differential-pressure sensor for commercial HVAC systems. The key purchasing distinction is that the instrument is configured for one pressure span and one signal output at the factory: the ZPM model’s selectable configurations cannot be assumed for FRP.

SpecificationBAPI dataTechnical selection note
Range and signalOne ordered fixed pressure range and one factory-set outputSelect by actual filter/duct DP span and BMS input range. Range and output are not field-selectable on this family.
Indication and zeroThree pressure-status LEDs and one autozero push buttonStatus LEDs are not an accurate continuous pressure register; perform proper zero procedure after mechanical installation.
Enclosure useBAPI-Box with optional attached static pressure tubeCheck the ordered pressure-tube fitting, ingress seals and actual environmental rating rather than inferring outdoor Ex protection.
Model alternativesStandard field-selectable ZPM or precision ZPM sold separatelySwapping a FRP with a ZPM requires signal scaling, enclosure and cable checks even when mounting looks similar.
Manufacturer documentationMaker offers model datasheet and installation/operation guideVerify order code and temperature-dependent accuracy from current OEM submittal rather than applying a generic ZPM percentage.

Instrument approval and exact option code

Pressure measurement, switching, zero setting, accuracy and housing approvals are variant-specific. IP66/NEMA 4 is not an ATEX/IECEx certification. Confirm the exact BAPI ordered part number, output interface, current electrical connection, calibration evidence and tubing installation before a safety or purchase decision.
