Vane Airflow Transmitter – Series AT400 & TAT420
The AT400 and TAT420 air velocity transmitters supply accurate air velocity and (TAT420) temperature data from a building or process airflow on a continuous basis to a computer, chart recorder, printer and meter or control circuit.
Description
The AT400 and TAT420 air velocity transmitters supply accurate air velocity and (TAT420) temperature data from a building or process airflow on a continuous basis to a computer, chart recorder, printer and meter or control circuit.
The THT500 humidity-temperature transmitters supply accurate humidity and temperature data from a room or process air source on a continuous basis to a computer, chart recorder, printer, meter or control circuit.
Every instrument has terminals for both DC and AC power and 0-1 V, 0-5V and 4-20mA output.
