Differential Pressure Transmitter(Indoor) Uses piezoresistive differential pressure sensor No flow-through structure, pressure ports are not interconnected Differential pressure measurement range of ±50 ... ±10,000 Pa Compact and easy to install Includes square root function for converting into air velocity Provides analog output, optional RS-485 communication function DIP switch to adjust range and square root function The eyc-tech PMD330 differential pressure transmitter (Indoor) is designed for indoor environmental monitoring. It uses a piezoresistive differential pressure sensor with a no flow through structure. The built-in square root function is used for converting into air velocity, and it provides flexible output options to meet the needs of different scenarios. Users can easily configure it using the DIP switch, making it an ideal choice for various differential pressure measurement applications.
