Product details
1、 Overview and Application:
At present, there are many types of contact level controllers, such as mechanical (resistive displacement, resistive rotation), electronic (tuning fork, capacitive, RF admittance), etc. Due to the complex working conditions of materials in the silo, various level controllers have various shortcomings. Especially sometimes, it is necessary to verify whether there is material in the silo in order to determine the electronic typeThe current status of the material level controller can only be determined by removing the controller and checking the actual situation inside the silo. If the pressure chamber cannot be disassembled at will, it is very inconvenient. Due to the complexity of the material situation in the silo, there is often a misoperation of the material level controller. In this case, is it a controller failure or a material level alarm? It's really hard to distinguish and can only be dismantledDetermining the controller poses great difficulties for on-site work.
For humans, what they see with their eyes or touch with their hands is the most reliable. Even the most reliable automatic control system needs to be equipped with manual control. Based on this principle, our company has created a composite level controller. By combining electronic (capacitive, RF admittance) and mechanical (resistive, manual) methods, the aforementioned challenges can be addressedreadily solved. After installing the controller, the material level status can be detected manually, and the electronic controller can be debugged without waiting for the actual occurrence of the material, greatly reducing the difficulty of debugging. In addition, when the level controller malfunctions, manual detection and alarm can be used, which is very convenient for industrial sites.
Electronic and manual complementarity is a common approach. It can also be combined with resistive displacement (or resistive rotation) to make them backup for each other. This product is widely used in industries such as steel, coking refractory, cement, dust removal, chemical fiber, electricity, grain, and road construction machinery.
2、 Technical parameters:
1.Installation flange standard:JB82-59，DN80，PN1.0
2.medium temperature:less than250Celsius
3.Medium density:Manual detection and resistance type greater than0.5can/Cubic centimeters (when the density is too light, it needs to be specially customized); Capacitive and RF admittance are density independent
4.Storage bin pressure: not greater than0.8MPa
5.Suitable for diameters not exceeding1.0Centimeter sized powder particles.
6.Explosion proof grade:dIIBT4
Specially customized for special requirements (precautions for use):
1.When manual measurement feels the presence of material but the RF admittance (or capacitive, etc.) level controller does not have a corresponding output, a switch signal can be output through the manual button.
2.When resistive switching is combined with RF admittance, capacitive switching, and tuning fork switching, users can use their respective outputs to determine the usage method of the material level signal. may also
By using the logic circuit specially equipped by our company, the two level signals are divided into“give”Logic“perhaps”“Logic serves as the output of the system. The terminal diagram of the dedicated logic circuit is as follows:
KSTo receive relay signals from RF admittance or capacitive, tuning fork, etc;KZTo receive signals from resistive relays; It should be noted that at this time, impedance shift and RF admittance or
Capacitive, tuning fork, and other output relays have a pair occupied by logic circuits.
output“give”Logic“perhaps”“Logic is selected by switches inside the junction box.
