YJJ HAFUHT0020L3AXT 20SLPM Gas Flow Sensor Is Used In Medical Anesthesia Equipment

Features:

HAF Series - High accuracy, bidirectional flow, long interface, tight mounting, 0 SCCM to 50 SCCM flow range, digital I²C address: 0x49, 5.0 Vdc power supply voltage.

The - Zephyr™ HAF series of sensors provide a digital interface for reading airflow data over the full flow range and temperature compensation range.An insulated heater and temperature sensing element help the sensor respond quickly to air flow or other air currents.

The Zephyr sensor is designed to measure the mass flow rate of air and other non-corrosive gases.Standard flow range can be used at ±50, ±100, ±200, ±400 or ±750 SCCM.Custom traffic ranges are also provided.These sensors utilize integrated circuits on the circuit board for full calibration and temperature compensation.

The HAF series compensates for temperatures from 0°C to 50 °C [32°F to 122°F] and can operate in temperatures from -20 °C to 70°C [-4°F to 158°F].ASIC based compensation enables digital (I2C) output and 1 ms response time.

These sensors measure the mass flow rate of the airflow based on heat transfer principles.They consist of microelectromechanical sensing systems (MEMS) containing thermal resistance microbridges, thin film platinum resistance deposited on silicon nitride thin films.The MEMS sensor chip is located within a precisely designed airflow channel to provide a repeatable response to flow.

Zephyr sensors provide customers with enhanced reliability, high accuracy, repeatable measurements, and the ability to customize sensors to meet many specific application requirements.The combination of a rugged case and a stable base makes these products extremely durable.They are designed and manufactured to ISO 9001 standards.

Product features

Total error band (TEB) as low as ±0.25 %FSS: The ability to perform very accurate gas mass flow measurements is often ideal for high-precision measurement applications

Fast response time: Enabling customer applications to respond quickly to changes in gas flow is critical for critical health (e.g., anaesthesia machines) and industrial (e.g., fume hoods) applications.

Wide range of gas mass flow detection: Zephyr offers standard flow measurement ranges of ±50, ±100, ±200, ±400, or ±750 SCCM, and customizable flow ranges, allowing more options for sensor integration into applications

Customizable flow range and configurable package type to meet specific end-user requirements

Full calibration and temperature compensation: Often eliminates the need for additional components associated with PCB signal regulation, reducing PCB size and costs associated with these components (e.g., procurement, inventory, and assembly)

Linear output: provides more intuitive sensor signal than the original output of the basic gas mass flow sensor, which helps to reduce production costs and shorten design and implementation time

Low pressure drop: Greatly improves patient comfort in health applications, reducing noise and system wear from other components such as engines and pumps

12-bit high resolution: Enhanced ability to detect subtle changes in gas mass flow, enabling customers to control applications with greater precision

3.3 Vdc low operating voltage options and low power consumption: allows use in battery drives and other portable applications

Asic-based I2C digital output compatibility: Easily integrated into microprocessors and microcontrollers, reducing PCB complexity and number of components

Height free: Customers do not need to adjust the errors caused by height changes in the system, do not need to buy additional sensors for height correction, so it can easily achieve integration and reduce production costs

Small size: takes up less space on the PCB, so it can be easily assembled on the PCB and reduce production costs;The reduction in PCB size also makes it easier to use in space-constrained applications
