Capricorn 2000EX™ Vehicle-Mount Weather Station

The Capricorn 2000EX Vehicle-Mount Weather System provides weather monitoring for mobile Command Post operations. Internal system components are permanently mounted in the vehicle. The telescoping sensor mast and affixed sensors are detachable for transportation storage, then simply clicks into place once on-scene – ready for immediate operations. The entire system is operational within minutes to provide critical weather information where and when it is needed.

The Capricorn 2000EX features a durable aluminum/stainless steel wind direction and speed sensor. This sensor offers two-degree compass-point wind direction resolution and superior accuracy.

Weather Parameters Monitored • Temperature • Barometric pressure • Wind direction • Wind speed with gust and average wind • Relative humidity • Heat index • Wind chill • Daily max/min • Rainfall (optional)

The 9-ft telescoping sensor mast is made of rugged anodized aluminum, with heavy-duty powdered-coated steel mounting brackets which are permanently installed on the vehicle.

Barometric Pressure

Capricorn 2000 Weather Station Barometric Pressure Sensor Housed in the Control Module, the barometric pressure sensor is a silicon shear stress strain gauge. This state-of-the-art sensor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high level analog output signal and true temperature compensation. The on-chip integration also results in high reliability and accuracy.

Accuracy: ± 0.03 in. Hg over range (at sea level, with temperature between 32° and 182°F (0°- 85°C)

Range: 27 to 33.96 in. Hg

Resolution: 0.01 in. Hg

Temperature

The Capricorn 2000 Weather Station comes standard with one temperature sensor with 50 feet of cable. Up to four temperature sensors can be connected with a maximum of 400 feet combined cable length. These digital, semiconductor-type probes all connect to a single port, reducing susceptibility to noise interference, reducing cost, and increasing accuracy. The sensors are calibrated at the factory traceable to NIST standards.

Accuracy: ± 0.9°F from +14° to 185°F (±0.5°C from -10° to 85°C), ± 3.6°F from -67° to 257°F (±2.0°C from -55° to 125°C)

Resolution: 0.01°F

  • Wind direction in 2-degree resolution
  • Wind speed displays as low as 1 mph
  • Quick-disconnect cable connector for easy sensor removal

Wind Speed:

  • Accuracy: ± 1% from 24 to 160 mph, ± 1% from 24 to 160 mph
  • Range: 0 to 160 mph
  • Resolution:1 mph
  • Starting threshold: 0.9 mph
  • Type: Sealed read switch

Wind Direction:

  • Resolution: 2 degrees
  • Accuracy: ± 4 degrees
  • Type: Precision Potentiometer

Relative Humidity

Capricorn 2000 Weather Station Relative Humidity Sensor This optional capacitive relative humidity sensor is compact and easy to use. It can be easily installed in a self-aspirating radiation shield for protection from the sun and rain. This sensor offers long-term stability with minimal drift. Because the sensor is a capacitive device, it will not be affected by surface contamination in unclean environments. Since the sensor element is socketed and laser trimmed it can be easily replaced in the field without any additional calibration. The relative humidity sensor comes with a standard 50-foot cable and a quick disconnect connector.

Type: Capacitance

Accuracy: ± 3% (or better) from 10 to 90% RH at 68° F

Temperature Effect: less than <±1.5% RH from 14° F to 140° F

Stability: ±2% RH over 2 years

Reporting Resolution: 1% RH

Range: 0 to 100%

Rainfall

Capricorn 2000 Weather Station Automatic Rain Gauge 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. Please call 1-866-625-8620 for details.
