Air Velocity

TM-IVL

The reliable TM-IVL air velocity transmitters work on the hot-wire measurement principle, which quarantees very good accuracy at low air velocity. The transmitters are suitable for air flow and temperature measurements in the air ducts. Air velocity transmitters are available with different measurement ranges and immersion lengths, with or without display.

TM-IVLJ

The reliable TM-IVLJ air velocity transmitters work on the hot-wire measurement principle, which quarantees very good accuracy at low air velocity. The transmitters are suitable for air flow and temperature measurements in the air ducts. Air velocity transmitters are available with different measurement ranges and immersion lengths, with or without display.

TMF-DAFA

The Series TMF-DAFA Air Flow Indicator and Alarm alerts users of low or no air flow conditions in pipes utilizing a thin, field trimmable vane to sense the air flow rate. An 85 dB audible buzzer alternates with a bright red LED to alert users when the air flow rate drops, indicating low or no flow in the pipe. The TMF-DAFA is battery powered to provide versatility for where it can be installed, and offers a yellow LED to indicate a low battery. This device is ideal for monitoring radon mitigation systems by detecting a loss of air flow in the pipe and providing a signal to homeowners if the fan has stopped operating.

Air Volume

TM-IML

TM-IML is made for detecting and controlling air volumes in air handling units and room spaces. The transmitter includes versatile preset settings for most common fan models and a common formula for air flow volume. Excellent accuracy of the measurement is guaranteed by the automatic zero point calibration. The proper range of measuring can be chosen at commissioning from four different ranges.

TM-PP

Die TM-PP Luftströmungssonden dienen zur Luftmengenmessung zusammen mit dem Regler TM-IML. Die Sonden sind einfach an vorhandene Kanäle zu installieren.
