High Pressure Air Flow Sensor

Inside the sensor there s a sense element with a heated surface.

High pressure air flow sensor.

High precision integrated pressure sensor included. Today the lx100 series of low pressure sensors are the most accurate and reliable sensors available for measuring interface pressure distribution as low as 0 1 psi. As gas flows across the sense element heat is transferred from upstream to downstream. Pro software for easy and efficient analysis and logging included.

Sensirion s differential pressure sensors in a bypass configuration are the ideal cost effective choice for measuring air flow with high accuracy robustness and stability. High quality optional sensors for measuring air flow temperature humidity pressure degree of turbulence heat radiation co2 illumination intensity pmv ppd and wbgt. At the simplest level an airflow sensor or more precisely a mass air flow sensor is a device with two pressure ports where gas flows from one port to the other see figure 1. Silicon chip design is created from thin film thermally isolated bridge structure containing both heater and temperature sensing elements.

In a bypass configuration the differential pressure sensor is placed over a pressure drop element orifice. This provides rapid response to the air or gas flow and amount and direction delivering a proportional output voltage. It is designed to meet the instantly increased demand for respiratory applications the flow of air and oxygen at rates from 10slm to 240slm is measured with excellent accuracy and extremely high speed.
