PHM330 Differential Pressure Transmitter

● Uses a hot-wire type differential pressure sensor
● High sensitivity to low differential pressure, low zero-point drift, minimum measurable value down to 1 Pa
● Pressure resistance up to 1 bar, differential pressure measurement range of ±50 ... ±1500 Pa
● Aluminum alloy housing, IP65 protection rating
● Includes square root function for conversion to air velocity and airflow, with simultaneous display on screen
● Provides analog output with RS-485 communication function
● DIP switch for adjustable range and square root function

The eyc-tech PHM330 differential pressure transmitter, equipped with an aluminum alloy housing, is less affected by the external environment, ensuring stable and reliable airflow measurement. Its sensing element
is a hot-wire type sensor, which provides excellent zero-point stability and the ability to detect low differential pressures, ensuring precise measurements at low air velocities.
