respiratory gas sensor flow sensor

Breathing and Respiration | First Sensor

If respiratory air or gas flows through an artificial constriction in the flow line with a very low flow resistance, for example a screen or a laminar flow element, a minimal pressure drop results over the element, this representing a measure for the volume flow. These low differential pressures can be logged with highly accurate sensors and converted into an electrical signal. The ...

Spirometers | First Sensor

A minimal pressure drop results over the element, this representing a measure for the respiratory flow rate (respiratory volume per time). These differential pressures can be logged with highly accurate sensors and converted into an electrical signal. So as not to unnecessarily burden the patient's respiration, it is important to keep the flow resistance as low as possible. Where respiratory ...

What is a Gas Sensor? Construction, Types & Working of Gas ...

2019-06-04· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated. MQ-6 Gas Sensor ...
