As you know, the main prerequisite for doing any work is to have proper information about that subject. Regarding selection, checking prices, buying and know more about level transmitters, the contents are included below so that you, dear visitors of the specialized website of Damatajhiz, can use these tips to choose and buy different types of radar, ultrasonic and magnetic level transmitters from Enders Hauers, Rosemont, Korone, Ayew Teknik, Siemens, etc. brands in bulk.
A level transmitter or level transmitter is a tool to detect and control the level of liquids and solids. The difference between "level switch" and "level transmitter" is that in the level switch, after the fluid reaches a certain level, a warning of disconnection or connection of the flow is issued through the switch. But at the level of the transmitter, the command may be issued to the output after the material level reaches a certain level (point level) or repeatedly after each measurement (continuous level). Level transmitters measure the level of water, viscous liquids, fuel, and dry and solid materials such as powder and granules. There are different surface transmitters, such as radar surface transmitters, guided radar, ultrasonic, guided microwave, magnetic, hydrostatic, etc. Join us in introducing and checking the performance of various surface transmitters in the rest of this article (for wholesale purchase).
The level of radar transmitters is usually installed on top of the tank. By sending high-frequency radio waves and calculating the difference in frequency and time in the round-trip waves, they calculate the level of the substance. These tube transmitters are non-contact and do not require calibration when changing liquids. The level of the radar transmitter has high accuracy (±0.5 mm).
Guided radar level transmitters are usually installed on top of the tank and calculate the material level by sending radar pulses along a high-frequency probe and calculating the difference in impedance and time in the back-and-forth pulses. The level of the guided radar transmitter has high accuracy (±0.2 mm).
The level of ultrasonic transmitters also works non-contact and is installed on top of the tank. By sending an ultrasonic pulse to the material's surface in the tank and reflecting it, this level transmitter calculates the time between the pulse and return in the tank's empty part and subtracts this value from the total height of the tank, and calculates the level of the material in the tank. These tube transmitters do not need to be calibrated with fluid.
The tube of the guided microwave transmitter sends the microwave waves through a rod to the surface of the liquid. When microwaves hit the liquid's surface, they return to the top of the sensor rod and the inner part of the transmitter tube; this time difference of the signal from the head to the end of the rod represents the level of the material inside the tank. The guided microwave level transmitter is suitable for liquids.
Magnetic level transmitters use small, floating magnetic objects to determine the level of material in tanks. These small objects are located in a column. Their movement rate is measurable when the floating particles are placed on the liquid's upper surface in the tank. As the column containing the float is filled and emptied, the level of the liquid is continuously measured.
The capacitive transmitter level has a capacitor, including a di-electrode. A non-conductive material is filled between the two electrodes to help store the electric charge. As the dielectric increases, it can store more range of energy. These tube transmitters measure the material's level inside the tank by measuring the capacitance level due to the change caused by the change in the surface formed by the probe and the tank wall. Thus, the capacitance will be low if the probe is in the air. When the tank is complete, the probe goes into the material, and the capacitance increases. These tube transmitters need to be calibrated after changing the fluid.
The hydrostatic level transmitter tube is also a pressure transmitter tube. Hydrostatic transmitters determine the liquid level by measuring the pressure of the stagnant liquid—the greater the force of the liquid in the tank, the greater the volume.
