Vela Wind Sensors

Barometric Pressure: A solid state pressure sensor built into the sensor electronics provides accurate measurement of barometric pressure changes over a wide range. Electronic temperature compensation is included for highest accuracy over the operating temperature of the sensor.

Accuracy: ± 2 mbar

Range: 500-1100 mbars

Resolution: 0.1 mbar

Both temperature and humidity are built into the temperature shield at the bottom of the sensor package. The integral shield limits errors due to solar radiation. The RH sensor is a capacitive element enclosed in a protective membrane.

Temperature Range: -40 to +60°C (-40 to +140°F)
Temperature Resolution: 0.01°C
Temperature Accuracy: ± 0.5°C
Humidity Range: 0 to 100%
Reporting Resolution: 1% RH
Humidity Accuracy: ± 4%
Vela Weather Station Shield

The tipping bucket electric rain gauge is composed of a complex spun collector funnel with a knife edge that diverts the water to a tipping bucket mechanism. For each tip, a magnet causes an electronic pulse that is recorded. The rainfall sensor is completely automatic - spent water drains out of the bottom of the housing, hence, the instrument requires no servicing.

Accuracy: ±1% at 2 in./hr or less

Resolution: 0.01 inch

Heated rain gauge is available.

Vela 420 Weather Station

Communication connection options between sensor head and monitoring device. Click heading to expand for details.

Included with the Vela Weather Station is a 50-foot section of sensor cable which connects to the Interface Module.

A standard 7-foot serial communication cable connects the Interface Module to a computer or display console. Extra length RS-232 cable is available up to 200 feet, catalog number 8233.

For lengths from 200 to 4000 feet, refer to the RS-485 Short Haul Modem option below.

Wireless transceivers offer a cable-free means to remotely monitor weather information when hardwire installations are not feasible or practical.

For fixed-mount weather stations, 2.4 GHz and 900MHz wireless transceiver options offer outdoor line-of-site range at one mile and 20 miles, respectively.

For the wireless Vela Weather Station, a transceiver is housed in a weatherproof enclosure near the sensor head. A single transceiver is connected to the Interface Module at the data display site, which then is connected to a Weather Display Console and/or computer.

These stations require power at the site of the weatherproof enclosure. This power can be AC, battery or solar. The Orion sensor head requires significantly less power and is a good choice for solar or battery-powered operation.

A wireless weather station system configuration would include the weather station itself with display or software, plus a weatherproof enclosure and transceivers.

This device connects the weather station to a Local Area Network (LAN). At the monitoring computer a driver creates a virtual serial port and converts the data to be read by the available terminal program or weather software such as Weather Master or WeatherView 32.

For weather monitoring applications situated in a large facility such as an industrial plant or hospital, instead of running miles of cable from the weather station on the roof to a computer on the first floor, users can take advantage of existing LAN cables to hook up.

This device provides for the flexibility of placing the weather station any where close to an Ethernet connection.

Includes a power supply, driver and Ethernet cable.
