Festo
539679
Pressure sensor SDE3-...
The Festo 539679 is a piezoresistive pressure sensor with a display capable of measuring relative pressure, differential pressure, or dual relative pressure across a measuring range of -0.1 MPa to 1 MPa (-1 bar to 10 bar or -14.5 psi to 145 psi) with an accuracy of 2 %FS to 3 %FS. Certified for ATEX Zone 2 gas (II 3G Ex ec IIC T6 Gc X) and Zone 22 dust (II 3D Ex tc IIIC T80°C Dc X) environments, this component operates in ambient and medium temperatures from 0°C to 50°C using compressed air as per ISO 8573-1:2010 [7:4:4] with optional lubricated operation. It carries RCM compliance, c UL us recognition, CE marking per EU EMC, ATEX, and RoHS directives, and UKCA marking per corresponding UK instructions.

Request a QuoteWhy 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.
