Vane Anemometer and Arrays

HD Vane Head Anemometer


This Vane Anemometer is our most robust version of the highly successful, 100mm diameter, rotating vane head anemometer. It is supplied with fully potted high temperature electronics and housed in an aluminum enclosure. Each vane head is supplied calibrated with a certificate charting its’ output in Hz versus True Velocity. Each Vane Head Array system is also supplied fully calibrated so that the indicated Velocity on the instrument display is accurately set to the actual calibrated Velocity of the vane head supplied. We also supply custom built Multi Vane Head Arrays and have recently introduced the Single Channel Vane Interface Module (VIM). The VIM is a DIN rail mountable unit which provides 3 proportional industry standard outputs. (4-20mA, 0-10V 0-5V TTL). Each VIM is calibrated to a paired Rotating Vane Head so that the output from the VIM is proportional to the paired Vane Head Output Signal. Our Multi-Head arrays are custom built to suit customer requirements and can accommodate up to 10 heads each. Options for each array unit include an alarm module, averaging module, signal conditioning module for industry standard outputs and can be made to suit either 240Vac or 110Vac mains.
