The DT3617 Series foil strain sensor consists of two 10 kΩ precision strain‑gage grids arranged orthogonally on a one‑mil polyimide substrate, housed in a molded silicone‑rubber package with MIL‑S‑23586A encapsulation. The sensor includes temperature‑compensating bridge elements and axis‑identification markings for accurate alignment with principal strain directions.
The sensor meets MIL‑STD‑202 environmental requirements, offering a temperature range of –55 °C to +125 °C, vibration resistance up to 30 g (10 Hz‑2 kHz), and protection against humidity, salt spray, shock, and short‑term exposure to fuels and lubricating oils. Physical dimensions are 0.560" × 0.560" × 0.150" with an approximate weight of 13 g.
