Datasheet SDP2000-L Differential Pressure Sensor with Analog Output Calibrated and temperature compensated Excellent repeatability, no drift Product Summary 2 The SDP2000-L differential pressure sensor for air covers a measurement range of 3500 Pa (14 inch H O). Mounted in a PPS housing the SDP2000-L differential pressure sensor features a unique dynamic range, zero offset and unsurpassed long term stability. This makes it an ideal fit for demanding yet cost sensitive OEM applications in HVAC and medical equipment. The device is supplied with 5 V and provides a 0.254 V output. Although the output of the SDP2000-L differential pressure sensor is analog, the internal linearization and temperature compensation is performed digitally. This results in superior accuracy, outstanding resolution, and lowest temperature dependence. The outstanding performance of the sensor is based on Sensirions patented CMOSens sensor technology, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The differential pressure is measured by a thermal sensor element using flow-through technology. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications. Benefits of Sensirions CMOSens Technology High reliability and long-term stability Best signal to noise ratio Industry-proven technology with a track record of more than 15 years Designed for mass production High process capability Content 1.
