The flow sensor is a critical component of your anaesthesia device because it ensures proper ventilation during a procedure. It checks patient airway flow automatically 250 times per second, making it the “eye” of your anaesthesia system.
A flow sensor is a device that measures the flow of a fluid, such as a gas or liquid. Flow sensors use both mechanical and electrical subsystems to measure changes in the physical properties of a fluid and calculate its flow.
The Global Anesthesia Flow Sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Posifa Technologies Introduces Next-Generation Air Flow Sensors.Posifa Technologies has unveiled the next generation of its mass air flow sensors, which will be used in respiratory care as well as other medical and instrumentation applications.
The PMF83000 and PMF86000 series sensors are intended for use in harsh environments with high humidity and trace amounts of corrosive gases. The new sensors have a parylene coating that covers the entire PCB assembly, including the sensor die.
The sensors that have been introduced are crucial parts of ventilators, respirators, oxygen concentrators, nebulizers, and CPAP equipment, where they regulate the amount of air that patients receive.
These sensors have sturdy packages. The gadgets also offer mass flow measurement for fuel cell control, environmental monitoring equipment, and anaesthetic delivery.The third-generation thermal flow die from Posifa is included in the PMF83000 and PMF86000 series, which take advantage of the most recent advancements in microfabrication.
The sensor die delivers signal-to-noise performance and repeatability of 0.5% F.S. while using a pair of thermopiles to detect changes in temperature gradient brought on by mass flow.
Both series have a single primary flow path, which reduces the chance that water condensation and dust particles would block the bypass.The PMF83000 and PMF86000 series, which measure flow rates from 15 SLM to 100 SLM and 50 SLM to 300 SLM, respectively, have optimum reaction times of 5 ms typical and work in the -25 °C to +65 °C temperature range. The components provide bidirectional flow measurement and offer both analogue (voltage) and digital I2C outputs in the same package.
