● Provides analog output, optional RS-485 communication function
● DIP switch for adjustable range and square root function

The eyc-tech PMD330 (indoor) differential pressure transmitter is designed for indoor environmental monitoring. It uses a piezoresistive differential pressure sensor with a non-flow-through structure. The built-in square root function is used for conversion to air velocity and 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.
