8158418

Name: Festo 8158418 Flow sensor SFAH-1U-Q6S-PNLK-PNVBA-M8
Brand: Festo

Flow sensor SFAH-1U-Q6S-PNLK-PNVBA-M8

The Festo 8158418 is a thermal industrial component utilizing a heat transfer measuring principle for unidirectional mass flow and volumetric flow rate monitoring across a 0.02 l/min to 1 l/min measuring range. It operates within a -0.9 bar to 10 bar pressure range and a 0 °C to 50 °C medium and ambient temperature span, supporting compressed air as per ISO 8573-1:2010 [6:4:4], argon, and nitrogen. Certified with RCM compliance, c UL us listing, and CE and UKCA markings per EU and UK EMC and RoHS directives, the RoHS-compliant unit delivers a flow rate accuracy of ± (2% o.m.v. + 1% FS) at a nominal temperature of 23 °C.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
