Fujikura FPM-10PG Sensing Element/Gauge

The Fujikura FPM-10PG is a piezoresistive gauge pressure sensing element engineered for precise measurements of non-corrosive gases across a broad operating range. Packaged in Dual-In-Line format with through-hole mounting, it integrates directly into analog measurement systems requiring constant-current excitation and voltage output proportional to applied pressure. The sensor delivers fast response and minimal offset drift, making it suitable for laboratory, industrial, and research applications demanding reliable gauge pressure acquisition.
