Further specify below in conjunction with accompanying drawing:
Embodiment 1:
Digital radio frequency admittance admittance level controller, its composition comprises: one-chip computer 12, be connected with oscillator and shaping circuit thereof on the described one-chip computer 12, go back connected storage and operation display board on the described one-chip computer, described one-chip computer 12 and the functional circuit plate 9 that has oscillator that is attached thereto thereof and power circuit plate 11 are contained in the housing 8, and the main utmost point 1 of surveying of the oscillator that is connected with oscillator leans out outside the housing 8.
Embodiment 2:
Described digital radio frequency admittance admittance level controller, the described main outside of surveying the utmost point 1 one ends is surrounded by insulation course 2, and the outside of described insulation course 2 is surrounded by the auxiliary utmost point 3 of surveying.
Embodiment 3:
Described digital radio frequency admittance admittance level controller, the outside of the described auxiliary detection utmost point 3 one ends is surrounded by insulation course 4, and the outside of described insulation course 4 is surrounded by to pay surveys the utmost point 5.The described pair of outside of surveying the utmost point 5 has screw thread 6, is connected with described housing 8 by screw thread 6, and connecting portion studs with cushion rubber 7.
During use, after the installation energising, oscillator enters duty immediately, produces a frequency signal by the admittance value decision of detected material.The frequency of this frequency signal and detected material admittance value are inversely proportional to, and when detecting the utmost point and do not have the contact detection thing, the frequency signal of oscillator outputs to the numerical value that operation panel shows does not have material after delivering to one-chip computer and carry out data processing through shaping.When surveying utmost point contact material, operation panel shows material numerical value, and the difference of this two value is exactly the frequency variation by the change of detected material admittance value, can utilize on the operation panel+,--, the S key can set a numerical value, promptly export switch and get threshold value.Corresponding different materials can be exported different switching values.
