Pressure Sensors Engineered To Perfection

Strain Measurement Devices' miniature technology provides medical devices with precise noninvasive measurement of pressure and flow while offering control and validation of fluid deliveries in disposable sets. The extreme accuracy and repeatability in our OEM solutions provide key advantages for a variety of mission-critical applications. Pressure sensors are also ideal for harsh, high-pressure environments.

N365 Non-Invasive Pressure Sensor
Non-Invasive

Model N365

Non-Invasive Pressure Sensor

The N365 measures pressure through the wall of flexible tubing without any fluid contact. A reusable sensor body pairs with a low-cost disposable dome — eliminating contamination risk and enabling single-use disposable circuit designs. Dual output: I2C digital and 0–5V analog.

Choosing the Right Sensor

Proprietary Thin Film Strain Gauge

Our thin-film strain gauge process gives our sensors unsurpassed long term stability, even in the harshest environments. With our proprietary process of sputtering the circuit directly onto the pressure, the sensor surface is optimal for high-temperature environments. SMD can craft standard and custom designs with short lead times using nearly any material including aluminum, stainless steel, Hastelloy™, and sapphire. Customers have the option of welding these pressure sensors to a fitting or component of their choice. SMD Sensors provides welding services.
