Product Description:
YJJ ADP2100 ±500Pa Digital Differential Pressure Sensor Is Used In
HVAC Systems
Features:
ADP2000 sensor is a digital differential pressure sensor. Its
internal thermal sensor element measures the pressure difference of
gases. The sensor can achieve non-drifted and extremely
high-precision measurement of the pressure differences of air,
nitrogen, and oxygen. It also has excellent accuracy even at low
pressure differences. It has good performance in terms of
sensitivity, shock resistance, and temperature variation.
The ADP2000 sensor has a standard I2C interface, with a simple
communication method, and can be easily connected to a
microprocessor.
Application scope
The ADP2000 is specifically designed for high-precision
differential pressure measurement. The response time is up to 10ms,
and it can quickly respond to air, nitrogen, and oxygen. It can
adapt to harsh usage environments and low-cost HVAC applications,
such as VAV controllers, burners, heat recovery systems, and filter
monitoring; it can also be customized for specific scenarios
according to customer requirements, such as fire suppression
monitoring systems in smart fire protection; heating and
ventilation systems, fresh air systems, etc., for electrical
equipment; and precise control and monitoring of gas flow in
medical fields.
Main parameters of the ADP2100 digital differential pressure sensor
are as follows:
Core parameters
Measurement range: ±500 Pa (valid within the range of -500 Pa to
+500 Pa)
Accuracy: ±3% Reading accuracy (zero point accuracy is 0.3 Pa)
Response time: 10 ms
