Dragino's Wireless Differential Pressure Sensor is engineered to precisely measure pressure differences between two points, a crucial requirement in various settings. This sensor is particularly effective in scenarios where absolute air pressure is less relevant than the difference in pressures, such as across a valve in a pipe. Understanding these differences can indicate the valve's operational status or detect blockages, enhancing system reliability.

Versatile Applications: Suitable for both home and industrial environments, this sensor finds extensive use in offshore and subsea gas processing, remote heating systems, and other applications requiring meticulous pressure monitoring. Its ability to detect even slight variations in pressure makes it an invaluable tool in maintaining the efficiency and safety of these systems.

Advanced Wireless Connectivity: Featuring models that support LoRaWAN and NB-IoT wireless transmission, the Dragino Differential Pressure Sensor ensures reliable and long-range data communication. This versatility in connectivity options allows it to integrate seamlessly with various IoT platforms, including home automation systems and industrial monitoring networks.

Range of Pressure Measurement: Dragino's sensor caters to a wide range of pressure measurements, accommodating different industrial needs and specifications. This flexibility makes it suitable for a diverse array of applications, from delicate home systems to robust industrial processes.

Ease of Use and Integration: The sensor's wireless nature simplifies installation and integration into existing systems. Its compatibility with various IoT platforms allows for easy monitoring and data analysis, making it a user-friendly option for both technical and non-technical users.
