T017 TBF

Product catalog summary

Description: The TBF Leaf Wetness Sensor is a basic yet highly precise tool used in agrometeorology to measure the persistence of water droplets on leaf surfaces. This measurement is crucial for assessing phytopathological risks and the leaching of treatments from crops. The sensor features two gilded copper electrical circuits on glassonite plates, designed to mimic a real leaf. When wet, the system conducts electricity, indicating leaf wetness.

Main Features:

Easy installation and use
Accurate simulation of a real leaf
Virtually maintenance-free, requiring cleaning every six months

Technical Specifications:

Measurement Performance: Leaf wetness is measured with a transducer consisting of two gilded copper circuits. The measurement range is ON/OFF with a resolution and accuracy of 1 second.
Operating Conditions: The sensor operates in temperatures from 0°C to +60°C and humidity levels from 0% to 100%.
Outputs: The sensor provides an open drain output with a maximum tension of 24 V and a maximum current of 400 mA. A relay contact output is available upon request, with a maximum tension of 30 V and a maximum current of 1000 mA.
Power Supply and Consumption: The sensor requires a voltage supply of 6 to 22 Vdc. Consumption varies with open drain at 1.5 mA and relay contact at 15 mA.
Mechanical Specifications: The sensor's protective body is made of plastic and stainless steel, with a sensing element in copper and glassonite. It weighs 410 g and measures 135 x 67 x 232 mm. It features an IP67-rated 4-pole male connector for electrical connections.

Ordering Codes: The sensor is available with open drain or relay contact under the code t017-TBF-N.

TBF is a basic sensor for agrometeorology, typically used to investigate with a very high precision the persistence of water drops above the leaf surface. This indicator is fundamental to measure the residence time of water drops on the leaves, in order to identify phytopathological risks or the leaching of treatments from crops. TBF sensing element consists of two gilded copper electrical circuits placed on glassonite plates, which are specifically tilted to simulate a real leaf. Once the surface gets wet (for rain, condensation, dew, ice, etc.), the system enters into conduction closing the...
