Product Overview

SPX Thermal Dispersion Flow Switch - SF1710 - SFX10000-A1LAAA801 is a FINETEK SPX Thermal Dispersion Flow Switch configuration identified in the catalog by SF1710 and order code SFX10000 - A1LAAA801. The source documentation describes the operating method, product configuration options and technical limits for the family. This page content is therefore centered on the actual SF1710 identity rather than a generic description of the FINETEK range.

Thermal-dispersion flow sensing with one heated sensor and one temperature-reference sensor; increasing flow increases cooling and changes the differential signal. The listed design is intended to provide a usable process signal for integration into plant instrumentation, control, monitoring or protection systems, depending on the selected configuration.

Technical Capabilities

The supplied FineTek source material reports the following technical values for this family. Where the manufacturer shows more than one value because the range depends on model, construction, output or installation option, the complete range is retained rather than assigning one value to every variant.

• Water measuring range: 1–59 in/s (150 cm/s)
• Oil measuring range: 1–118 in/s (300 cm/s)
• Maximum operating pressure: Up to 1,450 psi (100 bar)
• Wetted materials: 304SS, 316SS, PVDF and polypropylene
• Outputs: NPN/PNP, N.O./N.C. relay or SPDT relay
• Temperature options: Standard, high-temperature and explosion-proof versions
• Indication: LED flow-status indication

Configuration and Selection

The product name, model identifier and order-code string should be checked together when selecting a specific item. Family-level values can be shared across configurations only where the source indicates that they are common; model-dependent values should be read from the corresponding configuration before purchase or installation. For this Excel row, the catalog identity is SPX Thermal Dispersion Flow Switch - SF1710 - SFX10000-A1LAAA801 with order code SFX10000 - A1LAAA801.

This content is written from the manufacturer information associated with the cited FINETEK family source and does not add unsupported operating values or unrelated product specifications.
