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.

Please see below the specifications for the Merit BP series:
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.
