Product type
MEMS pressure sensors are miniature devices that utilize Micro-Electro-Mechanical Systems technology to measure pressure changes. These sensors are typically made from silicon and integrate mechanical and electronic components on a single chip, allowing for high precision and sensitivity. They are widely used in various applications to monitor and control pressure in gases and liquids.

| Output type | Analog or digital |
| Operating temperature | -40 to 125 degrees Celsius |
| Supply voltage | 3 to 5 VDC |
| Accuracy | ±1% of full scale |
| Response time | 1 ms to 10 ms |
| Package type | Surface mount or through-hole |
When choosing a MEMS pressure sensor, consider the specific pressure range and output type that fits your application. It's important to specify the required accuracy and operating temperature range to ensure optimal performance. Additionally, inquire about certifications and tolerances that may be necessary for your industry. Quantities needed for production can also affect pricing and lead times, so be clear about your requirements when requesting a quote.
