P330W Absolute Catheter Pressure Sensor Evaluation Kit

NovaSensor P330W Absolute Catheter Presure Sensor Evaluation Kit offers a simplified way to read calibrated output from the P330B Catheter Die.

The kit consists of a sensor die soldered to trifilar wire and terminated to a printed circuit board (PCB). Users connect to kit via JST Connector or wires.

The P330B Piezoresistive (PRT) Pressure Sensor Die offers the same superior stability and sensitivity as in larger die, but in an extremely small footprint, this is ideal for invasive applications where small size is critical. Additionally, it has excellent measurement accuracy, which also makes it ideal for demanding applications with restricted dimensional profiles, such as medical catheters and IC packages. When excited with a DC voltage source, the P330W produces an mV output that is proportional to the applied pressure. The P330W employs a half-bridge design, which requires two external resistors to complete a full- bridge configuration. These resistors are included as part of the kit’s application circuit.

P330W Eval Kits are available in both, analog and digital output I²C configurations.
