New Digital Pressure Sensors from Sensirion
Digital differential pressure sensors.
Staefa, Switzerland — Sensirion AG has launched its new differential pressure sensors, calling them the SDP600 series. The new SDP6x6 sensor line features especially low energy consumption, making it suitable for long-term battery operation. The SDP606 and SDP616 sensors are designed to enter sleep mode after performing each measurement. They wake up when a "measure" command is received and enter sleep mode again after completing the measurement. The operating currents of a standard SDP600 sensor can be high as 6 mA, but the new SDP6x6 sensor is optimized for operating currents no greater than 400 µA. There is virtually no current drain (<1µA) in sleep mode.

This drastic reduction in power consumption allows the new sensors to be used in battery-powered applications. The new differential pressure sensors are excellent solutions for medical and HVAC applications, where high accuracy and reliability with very low energy consumption are required.

Along with the other products in the SDP600 series, the new sensors offer a digital I2C output and are fully calibrated and temperature-compensated. According to the company, by using calorimetric flow measurement, the CMOSens® differential pressure sensors achieve outstanding sensitivity and accuracy even at very low pressure differences (<10Pa). They also have very high long-term stability and are free from zero-point drift.
