Delivery time:Delivery time on request
The SM97A is a silicon micro-machined, piezoresistive pressure-sensing chip. It replaces the SM98A offering a better sensitivity and very low long-term drift.
The SM97A is designed for harsh media where absolute pressure needs to be accurately measured. In contrast to traditional pressure-sensing chips the media only comes in contact with silicon materials. Therefore, the electronic structures on the front side of the die will not be affected during operation. This results in a durable pressure sensor suitable for challenging applications.
This device is available in a full-scale range of 10 bar and 20 bar absolute (145 and 290 psiA) and is ideal for OEM and high-volume applications. Provided in die form, these sensors can be mounted on ceramic or PC board substrates as part of an OEM system.
They also may be packaged into proprietary, or application specific sensor lines. Backside eutectic metallization is available as an option. Dies are probed, diced, inspected, and shipped on UV release tape or blue tape.
