Dwyer AVPT-H10C1A12 is a pencil style air velocity transmitter with a temperature range of -4 to 140°F (-20 to 60°C). It has a standard accuracy of ±(5% reading +40 FPM) and a high accuracy of ±(3% reading +40 FPM). The transmitter requires a power supply of 24 VAC/VDC ±20%. It has a response time of 4 seconds and is housed in a NEMA 3 enclosure. The electrical connections are made through a plenum rated cable with 22 AWG conductors. It operates on clean air and can be mounted in specific orientations. The current consumption is less than 50 mA and it comes with probe lengths of 6" or 12". The output is an analog signal of 0-10 V (0-5 V configurable). The baud rate can be set to 9600, 19200, 38400, 57600, 76800, or 115200. The available ranges are 1000, 2000, 3000, or 4000 FPM (5, 10, 15, or 20 m/s). BACnet MS/TP can be selected at the time of order and there are options for a 5-pin M-12 cable of 24" (0.6 m) or a 5-conductor cable whip of 20" (0.5 m) or 78" (2 m).
