Professional rain and precipitation sensor
Professional rain and precipitation sensor with our patented unique single spoon tipping bucket is one of the most accurate and reliable precipitation gauges on the market and for over 38 years, we have supplied more than 300.000 rain gauges to 65 countries on 6 continents.
We deliver our products to OEM customers only and we are not competing with you for the end user.
Features and benefits
Beneath is listed the features and benefits of choosing Professional as your rain gauge.
Meteorological patented unique single spoon tipping bucket is one of the most accurate and reliable automatic rain gauges on the market. It gives you advantages in:
- More accurate measurements
- Only one adjustment screw which makes it easy to recalibrate.
- Bucket made in POM, which is a more dismissive material and therefore makes dust and dirt not stick so easily on the spoon and maximize water release.
Calibration is a very important issue for PRONAMIC and therefore all Professional rain gauges are manually calibrated. It gives you the guarantee for a very accurate measurement. Free selection of 0,1 - 0,2 - 0,25 or 0,5 mm resolution at the same price. Accuracy: +/- 2%.
Rains sensors with minimal maintenance
Our small rain gauges require minimal maintenance due to:
- Outer shell is made from ASA which makes the surface easy to clean and highly UV-resistant.
- High quality plastic materials and a simple design for a very long durability (10-20 years)
Rain gauge/Tipping Spoon
Professional measures the precipitation by means of a funnel (orifice 50 cm2), which leads the water down into the single self-emptying tipping POM spoon, held in place by a hard ferrite magnet.
The magnet always exerts just enough tension to allow the measuring spoon to empty in one quick movement (less than 300 ms) and then return to its normal position, ready to once again collect precipitation. This means the counter weight always remains the same opposite to other conventional two spoons tipping bucket rain gauges.
Diagrams of intensity are available in the datasheet here.
ASA plastic materials
The rain gauge made in molded thermoplastic, also known as ASA, which has high outdoor weather ability.
ASA is extremely resistant against the sun’s UV radiation, it is frost‐ and heat resistant, standing all climatically conditions.
The product is widely used in the automotive industry as well as several other outdoor applications.
The electronic printed circuit board with individually tested and high quality reed switches protected against extreme weather conditions such as extreme frost or heat. This include corrosion from salt water due to the PCB is coated with weather-resistant varnish.
The printed circuit board comes in two versions:
- Item no. 300.021: PCB No. 9601 (NC—normally closed) has male connection and 1 reed switch connected in series with a 1K ohm 1/4W resistor and a TVS-diode in parallel.
- Item no. 300.023: PCB No. 9602 (NC—Normally closed, NO—Normally open). Terminal strip with 4 connections / 2 outlets and 2 reed switches. Each reed switch is connected in series with a 1K Ohm 1/4W resistor and a TVS-diodes in parallel.
