Environdata Weather Sensors

Environdata designs and manufactures more than 20 high quality weather sensors.

These sensors are perfect for connecting to our Weather Maestro or WeatherMate data loggers or straight into your data logger, control system, PLC, BMS or RTU. Environdata sensors include:

• Wind speed sensors
• Wind direction sensors
• Rainfall sensors
• Air Temperature Sensors
• Grass, Soil, and Water Temperature sensors
• Relative Humidity Sensors
• Barometric Pressure Sensors
• Leaf Wetness Sensors
• Solar Radiation, PAR & UV Radiation Sensors

Our sensors use a unique digital pulse technology, ensuring reliable signals over cable lengths up to several hundred metres.
Each sensor is individually calibrated, allowing the same model sensor to be a plug-in replacement, without any on-site adjustment or reprogramming needed.

We can also supply sensors with industry standard 4-20mA output or voltage output convertors, along with signal conditioners and sensor alarms.  This means you can easily use these sensors in your existing system.

Sensor Alarm (SA12)

Environdata's SA12 Sensor Alarm is a low power microprocessor based device that provides an alarm output (relay contact or FET) based on the sensor or voltage input. The sensor alarm is suitable for Environdata weather sensors, or other environmental sensors.

Air Temperature Sensor

The TA40 Series Temperature Sensors are electronic sensors designed to measure air temperature.Two sensors can be used to measure air temperature and relative humidity using the wet and dry bulb method.

Humidity Sensor

The RH40 series relative humidity sensor features a field interchangeable tip that requires no field re-calibration. State-of-the-art semiconductor technology is employed, together with a thin film polymer that changes di-electric constant with atmospheric relative humidity.

Wind Direction Sensor

The WD series Wind Direction Sensors are sensitive wind direction indicators that give a variable pulse rate output and a visual indication of wind direction. The vane, arm and pointer turn the main spindle, which is support by two low friction stainless steel bearings. A special universal coupling provides a positive connection with the sensing transducer ensuring reliable and trouble free operation.

Wind Speed Sensor

The WS series Wind Speed Sensor uses a sensitive 3-cup anemometer to measure wind speed and wind run. Three conical shaped aluminium cups of optimum proportions turn the main spindle. The spindle is supported by two special low torque, stainless steel low-friction bearings. The body of the sensor is symmetrical and well clear of the three rotating cups,helps to minimise interfering eddies.

Tipping Bucket Rain Gauge

The Environdata RG12 Series tipping bucket rain gauge is sturdily constructed from polished stainless steel with a painted base and receiver funnel.

Barometric Pressure Sensor

The BP10 Series Barometric Pressure Sensors are designed to measure atmospheric pressure in the range 750 to 1050 hecto Pascals. The sensors use an integrated circuit sensor element, which has been laser trimmed for accuracy.

Solar Radiation Sensor

The SR10 Series Solar Radiation Sensor isa general purpose global incoming solar radiation sensor with cosine correction. It has been designed for recording hours of sunshine as well as total incident solar energy.

Soil Temperature Sensor

The TS10 Series Temperature Sensors are specially designed for measuring the temperature of soil, grass or water.

Leaf Wetness Sensors

The LW10 Series Leaf Wetness Sensor is designed to give an output proportional to leaf wetness with approximately the same wetting and drying characteristics as a leaf. 

Ultra Violet Radiation Sensor

The UV10 Series Ultra Violet Radiation Sensor uses a silicon-gallium-arsenide-phosphorous photovoltiac cell, mounted with an integral filter. This provides a standardised reading equivalent to the radiation falling on a non-reflective surface. 

Gypsum Block Soil Moisture Sensor

The Gypsum Block Soil Moisture Sensor provides a method of reading soil moisture as a moisture potential over a range of 0.3 Bars to 10.0 Bars, (very wet to very dry) in low to moderately saline soils of pH 4.5 or higher. 

Wet and Dry Humidity Sensor

The TA10 series temperature sensors are electronic sensors designed to measure air temperature. Two sensors can be used to measure air temperatureand relative humidity using the wet and dry bulb method. Improved design provides for faster and more accurate temperature sensing. Temperature stability of the new design allows realistic temperature measurement accuracy's of ± 0.2°C over the range. 

Specialised Sensors

Environdata can supply custom sensors that interface to our data loggers. Should you have a specific instrument that is required in addition to your weather monitoring sensors, please contact us and we will be happy to advise a solution.
