Product Description

The GZP197 invasive pressure sensor is designed for use in disposable blood pressure monitoring medical instruments and conforms to AAMI requirements for blood pressure monitors. Its core component is a silicon piezoresistive pressure-sensitive chip fabricated using MEMS technology, mounted on a ceramic substrate. Thick-film circuitry calibrates and compensates for the sensor, generating a high-precision standard voltage output signal referenced to the supply voltage. A cap attached to the ceramic substrate not only protects the internal structure from damage but also facilitates installation and use in the system. Gel is used on the pressure-sensitive chip to ensure insulation from external sources.

Function Description

The GZP197 pressure sensor is suitable for applications in medical and healthy care, automotive electronics, industry automation and other fields. Its key component is a silicon piezoresistive pressure sensor manufactured using MEMS technology . This pressure sensor consists of an elastic membrane and four resistors integrated into the membrane. These four piezoresistors form a Wheatstone bridge structure. When pressure acts on the membrane, the bridge generates a voltage output signal that is linearly proportional to the applied pressure.
