High Temperature Magnetic Level Gauges Radio Frequency Level Controller
Based on the principle of conductivity, the probe and the tank wall can serve as the two poles,the air and the insulated element becomes the medium in this situation. When the level of material rise to the probe, the medium air will be substituted by material, so the dielectric constant would be changed. As the dielectric constant of material is larger than that of air (=1), which will change the conductivity and impedance at the main time, the circuit board of L2000C will detect the change and enlarge it, by compare with the reference point, the circuit will generate a relay output accordingly.
The set of reference point is important for the unit generate a correct output.
Based the technical of RF, a radio frequency will be sent to the working
element and the guard element, which will cut off the current generated by the adhered material on the element.
By this way, the probe can measure the level of material without the influence of adhered material.
L2000C is designed and produced based on the technology of Princo’s point level controller. The technique of adhering proof circuit can ensure the accurate measuring of actual level of material. With the technique of surface sealing, the L2000C can work more reliable.
The standard probe of L2000C is L863C, of which the diameter is10mm, and the length of guard element is 150mm, the total length of the probe is 450mm. The flat probe L890C is suitable for measuring massive material which can avoid the damage of probe pole caused by material wallop. And, L863WC flexible wire probe and L864C probe for high temperature are available.
■Suitable for wide application: can be used to measure almost all kinds of material, fly ash, grain, powder, liquid, slimy material, electric material and non-electric material.
Adhering proof circuit: ignore the effect of adhered material.
■ Easy-on probe: No wire used to connect the probe and the controller, which allow the user remove it easily.
■ Suitable for application of high temperature and low temperature: -184℃ to 260℃, high temperature probe also be available.
■ Large output capacity: 2.5A/230VAC, or 5A/26VDC relay, with status light, time delay for 0~30 seconds.
■ Technic of surface sealing: Anti-vibration, ensure the steady work of circuit board.
■ Technic of hydraulic pressure: Strength the probe for pressure
■ Warranty: Ten years
