Capricorn FLX Control Module

Utilizing MEMS technology, the on-board barometric pressure sensor provides accurate pressure data with full temperature compensation. The sensor outputs are digitized by a high-resolution 24-bit analog to digital converter.

Accuracy: ± 0.03 in. Hg (1 hPa)

Range: 14.8 to 32.5 in. Hg (500 to 1100 hPa)

Resolution: 0.001 in. Hg (0.03 hPa)

Standard with one ambient 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.

Options include: Soil/Water Temperature, Panel Temperature, and Ambient Temperature Sensors

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)

Wind Sensors

This 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%

Relative Humidity

The optional 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.

Tipping Bucket Rain Gauge

The pyranometer or solar radiation sensor is calibrated to measure the shortwave radiation reaching the Earth's surface, measured in Watts per square meter.

Self-cleaning dome-shaped head prevents water accumulation.

Sensor head is potted solid to prevent internal condensation in humid environments.
