    Description Of The Ventilator NTC Temperature Sensor


    Temperature sensors of temperature measuring type are used in the ventilator. It is generally used to detect, control, and adjust the temperature in the airflow, which is more conducive to the patient's breathing.For temperature sensing, ventilator manufacturers can choose from sensing elements that can provide patients with warm and humid airflow to improve breathing comfort. Warm and humid air can also help patients reduce sore throats caused by inhaling cold, dry air. The discrete thermistor is usually installed directly in the air flow path to detect the air temperature. The sensor is used in conjunction with a microcontroller that detects the temperature of the airflow, and interacts with a controller that controls and regulates the temperature of the airflow.


    Feature Of The Ventilator NTC Temperature Sensor


    * High waterproof

    * High moisture proof

    * High precision

    * High sensitivity


    Design considerations and procedure of temperature sensor


    1Choose the shape acoording to customer's design or assemble requirements, and confirm the thermistor.
    2Confirm the thermistor element and other materials according to customers' requirement
    3Choose the suitable resistance,B value and tolerance
    4Choose suitable moisture-proof and insulation technology to meet customer's requirement
    5

    Choose suitable encapsulation structure to meet performance requirements of mechanical shock resistance

    6Meet customer's special requirements.
