Universal anemometer UAM 118A

Small standard dimensions enable easy incorporation of UAM118A in instrumentation panels or also be used as a lightweight, battery powered portable instrument.

UAM118A can accept either digital wind sensors with the frequency output for wind speed and up to 8-bit Gray code output for the wind direction, or analogue sensors with voltage or current outputs. All standard AMES optoelectronic wind sensors are suitable (KVT60A, VMT107, DHV39, DSV39A).

Sensors may be connected as follows:
• from distances up to 100 m directly by a shielded signal cable
• from distances up to 30 km using a local modem module MMP 121 (300 Bd, CCITT V21 or Bell 103) and 2-wire unshielded telephone line

Data are indicated on a big, easy-to-read colour LED display. Adjustable intensity of display illumination enables good visibility in all light conditions from the direct sunlight to the total darkness.

Displayed data:
• numerically: real time / date, maximum wind speed in the averaging interval, instant wind speed, instant wind direction (or minimal wind speed in the averaging interval), wind speed alarm threshold, mean wind speed.
• on the graphic circular scale: instant (or alternatively mean) wind direction, variability sector of wind direction;
• status data: averaging interval, data processing mode (vector or scalar), wind speed units (m/s, km/h or knots), alarm status and power status.

Built-in microcomputer enables various averaging intervals: 2minutes, 10 minutes, 30 minutes, 1 hour, or coustom preset value. Wind speed can be given in m/s, km/h or knots. Anemometer features scalar or vector wind data processing and adjustable alarm threshold. The alarm can be independent of the wind direction, or we can limit it to wind direction fom one or two sectors. The alarm is acoustic and visual, and at the same time a free-potential contact is activated to turn on external alarm devices.

Wind data are stored in the internal memory with battery backup.

UAM118A has 4 analogue outputs to connect an analog recorder, CENTRONICS output for a matrix printer (enabling graphical or numerical data printouts), RS 232 link to the external computer, and CCIT V21 modem channel. This channel enables 2-wire connections of distant sensors and remote indicators.
