N365 Non-Invasive Pressure Sensor
Quick Overview
The N365 is a compact two-part clamp-on sensor that measures tubing pressure without contacting the fluid. The low-cost disposable dome snaps onto the reusable sensor body — providing a clean, cost-effective solution for single-use medical and fluid-handling OEM systems. Both I2C digital and 0–5V analog outputs are available simultaneously, allowing direct integration into microcontrollers, PLCs, and embedded OEM platforms without additional signal conditioning. Every sensor is measured across the full pressure and temperature profile and shipped with a detailed calibration sheet.

Key Features
Non-Invasive Measurement
Pressure measured through the disposable dome — no fluid contact with the reusable sensor body at any time.
Disposable Dome System
Single-use polymer dome attaches securely to the sensor housing. Designed for high-volume OEM applications.
Dual Output: I2C & Analog
24-bit I2C and 0–5V analog outputs operate simultaneously for direct MCU and PLC integration.
Low Power Design
Draws less than 3 mA at 3.3V — ideal for battery-powered and portable medical OEM designs.
High Long-Term Stability
Thin-film sensing element provides drift of less than 0.1% full-scale per year.
ISO 13485 Certified
Designed and manufactured to medical quality management standards for OEM device integration.
