Different Types Of Grain Level Indicators

By Krystal Branch


Like other professionals, farmers need to use various facilities and equipment to make their work easier and to ensure that their farm produce is in good condition. There are various types of facilities used by farmers among them being elevators and silos that are used for storing farm produce. Silos for instance come in a variety of sizes and these structures are made of different materials. If you want to know the amount of grain storage space in your silo, it is essential to know the different grain level indicators and the purpose for which they are used for.

Rotary paddle bin indicator is one of the devices that have a rotary motor, which rotates a paddle. This device works by turning profusely when placed in empty space and switching off when there is no storage space. The turning of this device enables one to know the condition of his or her store and be able to take the appropriate measures.

A tilt switch mercury-free sensor is another essential device. It is usually controlled automatically using a remote control to determine the available storage space in silos. Therefore, the farmer has to move it through his or her silo to know whether it is filled up or not.

Tilt mercury sensors are connected to control systems or controlled by use of remote controls. The mercury contact state in this device would change when the silo is not filled up. In case the store is full, the mercury contact state would remain unchanged meaning it would retain its state and position.

Mechanical level indicator comes with mechanical moving parts. When moved through the store, a steel ball on the detector would depress the electrical switch once the store is filled up. Whenever the silo is not filled up, this detector would just remain on the same position which is resting over the electrical switch. This product is usually cheap and can be found in various designs.

Some other common essential sensors are the weight and cable detectors. These are made to operate by taking measurement of the distance moved by the cable through the store. Once the distance is obtained, it is then transferred into a control unit by use of a digitized communication control connection. The control unit then works to determine the amount of free space by evaluating on the obtained data.

You can also use the ultrasonic continuous level sensor to determine the free space in your silo. This device is made to measure the time taken by a sound flight that is generated by a sensor. It is designed to measure such distances without coming in contact with the silo components. Using this device can however lead to some wrong measurements especially when the internal dust in the silo absorbs some of the produced sound.

Grain level indicators are crucial products for anybody searching looking for ways to be able to manage their farm produce in their stores adequately. These products are available in a number of options; thus increasing variety when one wants to buy them. It is usually essential to look for the benefits and disadvantages of utilizing each one of these sensors to enable you purchase the most suitable one depending on your needs.
