Rain Sensor Bracket MIM Parts

Product Description

The CG-04 tipping bucket rain sensor is a hydrological and meteorological instrument, which is used to measure the rainfall in nature, and at the same time convert the rainfall into digital information output in the form of switching value, so as to meet the requirements of information transmission, processing, recording and display. Waiting for needs. This instrument is composed of rain bearing parts and metering parts. The rain receiving port adopts a diameter of Φ200mm. The metering component is a tipping bucket mechanical bistable weighing mechanism, and its function is to convert the rain depth in mm into a switch signal output.

Product Features

• Small size, easy installation; high precision, good stability

• Good linearity, long transmission distance, strong anti-interference ability

• Mesh holes are designed at the funnel to prevent leaves and other sundries from blocking the rainwater from flowing down

• The support system of the tipping bucket parts is well-manufactured and the frictional moment is small, so the tipping bucket parts are sensitive to turning, stable in performance and reliable in operation

• The shell of the instrument is made of stainless steel, no rust, good appearance quality

• The rain receiving port is made of stainless steel skin as a whole, with high finish and small error caused by stagnant water

• There is a level adjustment bubble inside the chassis, which can assist the bottom corner to adjust the equipment to the level

Working and storage conditions

Working temperature: -40～85°C Working humidity: 0～100%RH

Storage temperature: -40～125°C Storage humidity: <80% (no condensation)

Working principle

The rainwater collected by the water receiving port passes through the upper cylinder (funnel) and is injected into the metering tipping bucket. The tipping bucket is injection-molded with engineering plastics and divided into two equal-volume triangular chambers with a middle partition. Rain sensor bracket MIM Parts is a mechanical bistable structure, when one chamber receives water, the other chamber is in a waiting state. When the volume of rainwater received reaches the predetermined value of 0.2 mm, it will fall over due to gravity and is in a waiting state, while the other cell is in a working state of receiving water. When the amount of water it receives reaches a predetermined value, it overturns itself and is in a waiting state. A magnetic steel is installed on the side wall of the tipping bucket, and it scans from the side of the dry reed tube when the tipping bucket turns to make the dry reed tube on and off. That is, every time the tipping bucket is overturned, the dry reed switch is connected once to send a switch signal (pulse signal).
