  • T-DCI-F300-1x3

Air Velocity and Temperature Sensor

T-DCI-F300-1A3 • T-DCI-F300-1B3 • T-DCI-F300-1C3


The F300 series sensors are versatile, rugged, high-performance air velocity and air temperature sensors. Designed with conformal coated electronics and sealed enclosures, F300 sensors area suitable for demanding applications, including those in corrosive or alkaline environments. With a robust, splash-proof design and UV-tolerant construction, F300s are built to handle a wide range of product and process-control air flow applications.

Requirements for use with specific data loggers:

  • HOBO MX1100 series: a 0-5 Volt DC input cable (SD-VOLT-05) and external power provided by an AC adapter (AC-SENS-1)
  • HOBO U12, UX120-006M, or ZW series: a 0-5 Volt DC input cable (CABLE-ADAP5) and external power provided by an AC adapter (AC-SENS-1)
  • HOBO RX3000: an analog input module (RXMOD-A1)
  • HOBO U30: an analog input module (VIA)
  • HOBO H22: an analog input module (S-FS-CVIA)

This adds the ability for users to be able to measure air velocity (in ducts, e.g.) from which CFM can be computed.
