- Disposable Pressure Catheters - Intrauterine - Intracranial - Body NovaSensor’s P162 piezoresistive pressure sensor die is offered in a miniature 1150 x 725 mm die that is small enough for three French catheters. The small die size is made possible by NovaSensor’s proprietary Silicon Fusion Bonding (SFB) process. When excited with an AC or DC voltage source, the P162 produces a mV output that is proportional to input pressure. The P162 is in a halfbridge design, where external resistors are needed to complete a full bridge configuration. Amphenol Advanced Sensors

Values measured at 0.6 mA and 71.6°F (22 °C) unless noted with 800 Ω resistor between +Out and –IN, and –Out and –IN. Die performance will vary depending on die attach material. The die attach material should be chosen to minimize package stress transmitted to the sensor die. 2. Sensitivity at 100 mmHg. 3. Extrapolated error at 300 mmHg by straight line through 0 and 100 mmHg pressure readings 4. Topside pressure. 5. Percent of the bridge resistor with the lowest value. Symmetry is the difference between the two bridge resistor values. 6. A protective coating must cover the sensor die for use with saline and other fluids. 7. 15 °C to 40 °C. Shipping And Handling Wafers are shipped in protective plastic containers, and if needed, die can be shipped in gel paks. The wafers are sawn on sticky tape with plastic rings. All sensor wafers are electrically probed, visually inspected. All rejects are marked by an ink dot. Each wafer will be labeled with the lot number wafer number, device number and the number of available sensor die.
