Honeywell’s new small piezoresistive silicon pressure sensors offer a digital output for reading pressure over a specified full-scale span and temperature range in high-volume medical devices and consumer appliances.
The MicroPressure Series sensor is calibrated and compensated over a specific temperature range for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board application specific integrated circuit (ASIC). Measuring just five millimeters by five millimeters, the MicroPressure sensor is ideal for applications that require greater accuracy with a small footprint.
The compact and highly accurate pressure sensors can be featured in medical devices, such as blood pressure monitors and air-suction pumps, as well as consumer appliances, such as coffee makers, high-efficiency washing machines and dishwashers.
For medical devices, such as non-invasive blood pressure monitors, the MicroPressure sensors’ small size and low power consumption allow for a compact product design and longer battery life. In coffee makers, the sensors offer a high level of accuracy to help ensure that the appropriate amount of water is available in the reservoir. This allows the machine to reliably produce a better cup of coffee every time.
The MicroPressure board-mount sensors feature:
- Strong stainless ports for product durability
- Absolute and gage pressure ranges
- ±40mbar to ±2.5bar; ±4kPa to ±250kPa; ±0.6psi to ±30psi
- Low power consumption to support longer battery life for products
- Support for multiple port configuration options
