EF-x2000-B Bleed Airflow Measurement with Temperature and Alarm Capability

Brand: EBTRON, Inc

The EF-x2000-B is a unique measurement device that can detect very small pressure differentials (as low as 0.0002” H2O) between two adjacent spaces by sensing the airflow rate induced by the pressure gradient. 

The EF-x2000-B can be used to determine the airflow rate across fixed openings when a reference airflow rate is provided.
Features

  • Bi‐directional Airflow Measurement
  • Detect ΔP as low as 0.0002″ H₂0
  • Airflow (or ΔP) and Status Alarm
  • Temperature Output Capability
  • Analog and RS‐485 Output Models
  • Dry Contact Relay
  • 1/2″ NPT Female Pipe Connections
  • Remote Transmitter with LCD Display
  • 3‐year Warranty
