                          • SFC66000

                          • The SFC6000 mass flow controller is Sensirion’s next generation mass flow controller, impressing with an unbeatable priceperformance ratio and a very attractive delivery time of eight weeks. While the industry is currently struggling with delivery times of 30 to 53 weeks, SFC6000 samples are available within two to four weeks. In addition, selected SFC6000 configurations are available in distribution, meaning you can order them for initial testing and evaluation today and have the product in your mailbox tomorrow.

                            The SFC6000 is very small and light and therefore allows the customer to optimize their devices in terms of size and weight. This is a decisive advantage, especially for portable devices. Furthermore, it offers great performance in terms of repeatability, accuracy, control range and speed. The SFC600 is highly integrated and has a very robust supply chain due to the very low number of electronic components used.

                      • Differential Pressure

                          • SDP800

                          • The SDP800 sensor family is Sensirion’s series of differential pressure sensors designed for high-volume applications. The sensors measure the pressure of air and non-aggressive gases with superb accuracy and no offset drift. The sensors cover a pressure range of up to ±500 Pa (±2 inch H2O / ±5 mbar) and deliver outstanding accuracy, also at the lower end of the measuring range.

                            SDP800特性模拟比率计电压output, which is configurable to linear or square root by a separate pin. The outstanding performance of these sensors is based on Sensirion’s patented CMOSens® sensor technology, which combines the sensor element, signal processing, digital calibration and analog output 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.

                          • SDP3x

                          • The SDP3x sensor family is Sensirion’s series of small differential pressure sensors designed for high-volume applications where size is a key requirement. It builds on the next generation CMOSens® sensor chip that is at the heart of Sensirion’s new differential pressure and flow sensing platform. The analog SDP3x sensors offer a calibrated and temperature compensated analog voltage output. The output signal is configurable: different measurement speeds, output curves and temperature compensations can be selected – even dynamically during operation mode.

                            • 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

                        • Gas metering solutions

                            • SGM6400

                            • The SGM64xx are the next generation gas meter modules, ready for the hydrogen future. Each module achieves MID accuracy with natural gas, LNG, biomethane, hydrogen blends and pure hydrogen. The maximum flow range for hydrogen is over 3x higher than that for natural gas. This means, no meter replacement is needed when natural gas in the network is gradually replaced with hydrogen.

                            • SGM6300

                            • The SGM63xx gas meter modules are Sensirion’s latest sensors for smart gas metering applications. Available in G1.6-G25 sizes, they achieve MID accuracy with natural gas, LNG, hydrogen blends and biomethane. Thanks to the latest generation CMOSens® flow chip, they are characterized by ultra-low power consumption. Sensirion’s thermal-mass module directly output volume flow at base conditions.
