The FST800-901 official range entry reads 0 ~ 100 kPa (customizable). That wording invites a configuration inquiry; it does not guarantee that every requested differential range is available, qualified or covered by identical acceptance evidence. A buyer specifying a different span needs a written offer identifying the actual measurement interval and units. Repeating the catalog range beside a custom requirement leaves the purchasing team without an unambiguous description of what will be delivered.

Comprehensive accuracy is listed separately as 0.5%FS. FS means full scale, not the instantaneous pressure reading. For a custom order, the supplier must clarify the full-scale basis and applicable conditions used for that accuracy statement. Do not silently apply the catalog maximum to a different ordered span, reinterpret the percentage as a reading-based tolerance, or infer a minimum measurable differential from it. Those interpretations are not established by the published entries.

Application Requirements for System Integrators

The FST800-901 is described for dry-gas pressure and differential pressure measurement, including air inlet pipelines and indoor-outdoor pressure monitoring. Custom-range procurement becomes relevant when a project specification asks for a measurement interval different from the published reference. The equipment designer should describe the required differential, its reference arrangement and intended conditions so the supplier can assess the request. An application label alone does not establish that the requested span is an offered configuration.

Nexisense Product Reference

Build acceptance around the offered FST800-901 configuration rather than the word customizable. The five official references below support a structured inquiry. They do not constitute confirmation of a particular custom span or define a permissible total static pressure. Output selection and range acceptance belong in the same order record, but each needs its own explicit supplier confirmation.

Product Parameters and Procurement Checks

Selection Guide

Request the lower and upper measurement limits, pressure units and pressure reference as distinct order fields. For differential measurement, ask the supplier to identify the reference arrangement and the sign convention applicable to the offered configuration. Do not infer bidirectional capability or an available negative range from a request for customization. The supplier response should distinguish confirmed supply from proposed development or an unanswered feasibility question.

Ask how the stated 0.5%FS accuracy is evaluated for that exact interval, including the full-scale definition and applicable environmental conditions. The official table lists operating temperature as -10 to 80 C and compensation as -10 to 70 C; these entries do not establish identical accuracy throughout the wider interval. Retain that unresolved scope in the acceptance discussion. No custom-span precision, resolution or detection threshold is established by this article.

Integration, Installation and Commissioning

Before approving receiving criteria, connect the confirmed measurement interval to the selected electrical output through supplier-approved documentation. Request the endpoint relationship rather than inventing a scaling formula for an unconfirmed variant. Define the required acceptance record, configuration identification and agreed tolerance basis in the purchase documents. If supporting records are requested, agree their scope and availability with the supplier; do not represent a requested record as an existing calibration certificate.

Keep differential span separate from other pressure limits. A stated measurement range does not define the permissible pressure common to the measurement connections. This review sets no total static pressure ceiling and gives no pressure-test procedure. Route missing limits or reference details back to the supplier before integration approval, rather than treating a custom-range quotation as a complete installation specification.

Illustrative Engineering Application

Illustrative engineering example: an air-handling equipment buyer requests a narrower interval than the catalog reference. The draft offer says custom range but omits the full-scale accuracy basis and output endpoints. Engineering asks for those details and the applicable acceptance record before approving the order description. This hypothetical specification review asserts no available custom variant, completed calibration, successful installation or measured project result.

Why Consider Nexisense

A Nexisense inquiry should identify the requested interval and ask for an explicitly confirmed FST800-901 offer. The related YF-P150 page discusses several measurement methods, but that wording does not establish a two-connection differential configuration equivalent to the FST800-901. Treat YF-P150 as a separate review candidate, with its pressure reference, construction and acceptance basis independently confirmed.

Frequently Asked Questions

Q1. Does customizable guarantee my requested range?

No. Obtain a configuration-specific offer confirming the interval, units and supply status.

Q2. Is 0.5%FS a percentage of the reading?

No. It uses a full-scale basis, which must be clarified for the actual ordered range.

Q3. Can the minimum measurable differential be calculated here?

No. The listed accuracy alone does not establish resolution or a minimum detectable differential.

Q4. What range information belongs on the order?

Record both limits, units, pressure reference and the supplier-confirmed configuration identity.

Q5. Are both listed outputs supplied simultaneously?

The catalog lists alternatives. Confirm the selected output and its documented endpoint relationship for the order.

Q6. Does the differential range establish total static pressure?

No. Obtain separate supplier information; this article defines no common-pressure limit.

Q7. Is YF-P150 an equivalent differential replacement?

Not automatically. General measurement-method wording does not confirm equivalent pressure connections or performance.

Q8. What makes acceptance evidence useful?

It must identify the supplied configuration and address the agreed range, accuracy conditions and review scope.

Summary

Turn the customization reference into a definite order: confirmed interval, units, reference, full-scale basis, selected output and agreed acceptance evidence. Keep unconfirmed availability, static pressure and performance conditions visible until the supplier resolves them.
