Constant Temperature Hot
RHRC introduces a new line of
Hot Wire Anemometry products designed specifically for wind tunnel and
water tunnel experiments. The Rolling Hills Research Corporation
Anemometer can be configured as a single unit or can be packaged in a rack
mount, which can simultaneously control up to 12 constant temperature
anemometer channels. Each channel
is manually tuned and has provisions for adjusting the overheat ratio,
compensating for stray probe cable inductance and can alternatively
amplify the raw anemometer signal by eight with a manual offset adjustment
to maintain the signal within the voltage limits of the power supply.
anemometer channel uses a 5:1 ratio wheatstone bridge and feedback
amplifier to drive the probe at a constant temperature.
