Honeywell’s new MicroPressure sensor enhances functionality of consumer appliances and medical devices

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.

“To enhance the performance of their products, design engineers need a cost-effective, application-specific pressure sensor solution that offers configurable options,” said Robert Robinson, product lead for Honeywell’s Sensing and Internet of Things business. “Our extremely small sensors feature an Internet-of-Things-ready interface to help customers bring compact, portable and lightweight products to market.”

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
  • ±40 mbar to ±2.5 bar; ±4 kPa to ±250 kPa; ±0.6 psi to ±30 psi
  • Low power consumption to support longer battery life for products
  • Support for multiple port configuration options
