Schneider EPP301LCD Panel Differential Pressure Sensor 0-250Pa with LCD
The SpaceLogic EPP301LCD is a high-performance panel-mount differential pressure transmitter featuring an integrated, backlit LCD screen. As the premium display-equipped upgrade to the standard EPP301, this unit maintains all class-leading sensory characteristics and multi-analog output configurations (4-20mA, 0-5V, 0-10V).
The LCD screen provides real-time local readouts of differential pressure (Pa or Inch WC) or calculated air velocity (m/s), delivering exceptional operational visibility and ease of maintenance for critical facilities including hospital isolation rooms, laboratory spaces, and high-standard electronic cleanrooms.
