Durable aluminum/stainless steel wind direction and speed sensor. The sensor offers 360-degree wind direction resolution and high accuracy. For installations subject to extreme weather conditions, a heated option is available.

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.

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.

Catalog No. 82601: This silicon photovoltaic 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.

Catalog No. 82605: This thermopile sensor meets ISO 9060 second class requirements. It measures solar radiation received by a plane surface, in W/m², from a 180° field of view angle. SR05 is ideal for general solar radiation measurements in meteorological networks and PV monitoring. The pyranometer is easy to mount and install, in particular with its ball leveling mechanism. The sensor outputs 0 to 1 VDC signal and can be interfaced directly to the Weather MicroServer’s analog channels.

Includes a tube mounting bracket and 50-foot cable. Additional mounting brackets are available.

Catalog No. 82603-6A: This thermopile sensor meets ISO 9060:1990 First Class requirements and features a sixty-four thermocouple junction (series connected) sensing element. The sensing element is coated with a highly stable carbon based non-organic coating, which delivers excellent spectral absorption and long term stability characteristics. It has improved performance due to the increased thermal mass and the double glass dome construction. The integral bubble level is raised to the top of the housing and can be viewed without removing the redesigned snap-on sun shield, which also covers the connector. The connector with gold-plated contacts allows for easy exchange and re-calibration.

The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets.

The sensor outputs 0 to 1 VDC signal and can be interfaced directly to the MicroServer’s analog channels.

Catalog No. 82603-10A: This thermopile sensor meets ISO 9060:1990 Secondary Standard requirements (highest possible ISO pyranometer performance category). The SMP10 extends this quality to applications where maintenance is difficult and/or forms a major part of the cost of ownership. The Internal drying cartridge is rated to 10 years if the housing is not opened.

The SMP10 uses a temperature compensated detector and has better linearity and long-term stability, lower thermal offset and faster response than a first class pyranometer.

The faster response time meets the requirements for solar energy monitoring.
