The FST800-1200 summary shows a Range entry of 0~10, 0~16 and 0~25 without a unit on that line. Those numbers are incomplete procurement information. They cannot establish a pressure span until the supplier identifies the intended unit and the exact offered configuration. Reading them as bar, MPa or kPa would add information that the captured catalog does not provide.

Pressure reference is a second, separate requirement. An engineering specification should state whether the ordered measurement is gauge or absolute, rather than assuming the reference from an application or model name. For this inquiry, both the missing unit and the unconfirmed order-specific reference remain unresolved. Neither should disappear when a buyer transfers the catalog entry into a quotation comparison or equipment data sheet.

Application Requirements for System Integrators

Compressor package buyers and automation integrators may encounter this gap while matching a sensor to a defined pressure duty. The useful starting point is the project requirement, expressed with its unit and reference. Submit that requirement to the supplier and ask which FST800-1200 ordering configuration meets it. Do not reverse the process by assigning a guessed meaning to a convenient catalog number.

Nexisense Product Reference

The following five entries separate the incomplete range reference from supported catalog context. The FST800-1200 page also lists a Packard connector, but that description provides neither an electrical terminal map nor confirmation of measurement range. Basic construction and enclosure information can support a broader review without resolving the missing pressure definition.

Product Parameters and Procurement Checks

Selection Guide

Request a written range statement that includes lower and upper endpoints, unit, gauge or absolute reference, and the code identifying the supplied configuration. Ask the supplier to show where those details appear in the quotation and applicable product documentation. If the proposed item differs from the original inquiry, require the change to be identified explicitly. A reply containing only 0~16 still leaves the original problem unresolved.

Keep the application requirement and supplier response in separate fields during bid comparison. This makes an unconfirmed entry visible instead of allowing a spreadsheet heading to imply agreement. If one supplier document supplies a unit but another remains ambiguous, obtain confirmation that both refer to the same version. Do not use a familiar compressor pressure convention to settle the discrepancy or assume that all three displayed spans share a verified ordering basis.

Integration, Installation and Commissioning

Withhold approval of PLC pressure scaling until the ordered span and reference are documented. Software labels, engineering units and acceptance records should use the same approved definition. This article gives no scaling formula based on the unitless catalog values. It also does not convert those values into another unit, since conversion would first require knowing what the original numbers mean.

The published +/-1%FS entry does not repair the missing range definition. Before using it in an error budget, obtain the ordered full-scale basis and the conditions under which the statement applies. Do not infer a smallest detectable pressure, an absolute error allowance or performance across every operating condition from the bare percentage. The procurement record should distinguish a published precision reference from an accepted, configuration-specific performance requirement.

Illustrative Engineering Application

Illustrative engineering example: an integrator preparing a compressor package data sheet finds 0~25 in the FST800-1200 summary. Instead of entering a unit in the PLC schedule, the integrator sends the project pressure requirement to the supplier and requests the exact range, reference and supply code. The data sheet remains marked pending clarification. This hypothetical review reports no commissioning result, measured accuracy or completed customer project.

Why Consider Nexisense

A precise inquiry to Nexisense should seek an identifiable pressure specification, not just agreement that the sensor suits compressors. Retain the supplier response with the approved data sheet and purchase line. YF-P150 is a related product for separate consideration, but its own range descriptions cannot supply missing FST800-1200 units. Treat any alternative as a new configuration review rather than a shortcut around this documentation gap.

Frequently Asked Questions

Q1. What is missing from the range summary?

The line lists 0~10, 0~16 and 0~25 without a unit. The ordered pressure reference also needs confirmation.

Q2. May buyers assume the numbers mean bar?

No. The source does not establish bar, MPa or kPa for that line. Obtain written clarification.

Q3. Does the compressor application establish gauge pressure?

No. Application naming does not confirm the gauge or absolute reference of the supplied configuration.

Q4. Can the values be used for PLC scaling?

Not as a complete pressure specification. Confirm endpoints, unit and reference before approving scaling.

Q5. Does +/-1%FS establish an absolute error limit here?

Not without the ordered full-scale basis and applicable conditions. Do not calculate from a guessed unit.

Q6. Does 304 stainless steel describe every wetted component?

No. The source identifies the housing material; request the complete applicable materials information separately.

Q7. Does IP65 confirm pressure capability?

No. It is an enclosure protection reference, not evidence identifying the pressure range or reference.

Q8. What should receiving documentation identify?

The supplied FST800-1200 configuration code and its approved endpoints, unit and reference, linked to the purchase specification.

Summary

Preserve the unitless range entry as an unresolved catalog item. Obtain the FST800-1200 endpoints, pressure unit, reference and supply code before approving PLC scaling or a full-scale error budget. Keep unrelated enclosure, material and connector descriptions within their actual scope.
