1.Product Overview:

The ADP2100 sensor is a digital differential pressure sensor in which an internal thermal sensor element measures the differential pressure of a gas. The sensor enables drift-free and extremely accurate differential pressure measurement of air and nitrogen and oxygen. Excellent accuracy also at low dropout pressure. It has good performance in terms of sensitivity, shock resistance and temperature change. The ADP2100 sensor has a standard I2C interface for simple communication and can be easily connected to a microprocessor.

2.Application Scope:

The ADP2100 is designed for high-precision measurement of differential pressure, with a fast response time of 10ms, and can respond quickly to air, nitrogen, and oxygen. It can adapt to HVAC applications with harsh environment and low cost requirements, such as: VAV controller, burner, heat recovery system and filter monitoring; it can also be customized and used in specific scenarios according to customer needs, such as: fire waste in smart fire protection Pressure monitoring system; pipe blockage monitoring and variable air volume control in electrical equipment such as heating air conditioning, fresh air system, building automation, precise control and monitoring of gas flow in the medical field, etc.
