Technical Description
Surface acoustic wave (SAW) sensors can be used to measure the concentration or mass of volatile and semi-volatile organic compounds in gases. They are characterized by high precision, small size, low power consumption, and rapid response. When gas passes through the sensor, it deposits on the sensor’s surface, causing a change in mass, which in turn leads to a change in the resonant frequency. After mixing frequencies, the output signal reflects the mass of deposited gas on the sensor and, indirectly, the current gas concentration.
