Merit Sensor BP Series

Merit Sensor BP Series

The BP blood pressure sensor series from Merit SensorTM is ideal for low cost, high-volume, disposable medical applications including blood pressure monitoring. This blood pressure series offers a pressure range of -30mmHg to +300mmHg with an operating temperature range of 15°C to +40°C, and an accuracy of ±1% of the reading (-30mmHg to +50mmHg). The BP series from Merit SensorTM is temperature compensated, dielectric gel protected and can easily be installed into a customer’s pressure device housing  and utilises a piezoresistive Wheatstone bridge with a chemically etched silicon diaphragm.

  • Blood pressure sensor
  • Pressure range from -30 mmHg up to +300 mmHg
  • Excellent burst pressure
  • Operating temperature of +15°C to +40°C
  • Accuracy of ±1% of reading (-30 to +50 mmHg) and ±3% of reading (+50 to +3000 mmHg)
  • Compliant with AAMI BP22 specifications
  • Dielectric gel barrier
  • Fully tested
  • Solid state piezoresistive sensor
  • Suitable for air, gases and liquids

Typical applications for the Merit SensorTM BP series include:

  • Disposable blood pressure measurement
  • Kidney dialysis machines
  • Infusion pumps
  • Surgical procedures

Please see below the specifications for the Merit BP series:

Merit PB series Specifications

1. Assumes 6 VDC, 22°C and after five second warm-up unless otherwise specified.
2. Output of sensor with no pressure applied and a150 KΩ resistor shorted across + IN to + OUT.
3. Over a temperature range of 15°C to 40°C
4. Normalised offset/bridge voltage – 8 hours after 20 second warm-up
5. Combined effect of sensitivity, repeatability, non-linearity and hysteresis errors
6. Sterilisation performed by customer.
