A radio frequency applied to the probe, through continuous analysis to determine the impact caused by the surrounding environment. Since all materials have a dielectric constant, and its conductivity are different from the air, when the probe is in contact with the material because the total impedance of the small capacitance change reflected in the offset. Because the power of the probe and the container wall constituting the two pieces of plate of the capacitor, the probe insulator and the surrounding air becomes a dielectric material, when the air (dielectric constant of 1.0) by any other material (dielectric constant> 1) when the substitution, capacitance effects can be strengthened. Thus changing the impedance applications. That change in capacitance value caused by changes in impedance. This effect was measured after the circuit, and then with the sensitivity settings (circuit) to establish a reference baseline compared. Proper sensitivity setting will affect the sensor output correctly changed. Anti-adhesion circuit probe allows measurement circuit to the accumulation of material on the probe is negligible, otherwise it will cause the sensitivity of failure. Anti-adhesion radio frequency circuit with the same potential and added to the sensing probe excitation. Since the current does not flow at the same potential, anti-adhesion circuit is cut off from the power of the probe is typically deposited material through the container wall to current flow. Such measured material surrounding the probe is energized, rather than the accumulation of material. First, the instrument characteristics: 1. Versatility: can be used to measure a variety of conductive and non-conductive medium, such as liquids, pastes, granules, powder, fly ash. 2. Can anti-adhesion: the use of patented anti-stick circuitry eliminates false signals due to the adhesion of materials produced. 3. Probe Detachable: No cables, electronic circuits can be dismantled at any time replace service between the electronic circuit and the probe does not affect access to the material. 4. Remote debugging: The controller is divided into two parts, controls and sensors, the control circuit can avoid the effects of temperature, vibration and other external negative factors; debugging is not affected by the mounting position (such as high altitude) is. 5. Double-point measurement: a controller can be equipped with two sensors, two probes, two different surveillance. 6. High and low temperature: for -184 ℃ to 260 ℃ operating environment, the other can provide suitable for higher temperature ceramic probe. 7. Output form: the DPDT relay output, while a status light to display the output state, and there are 0-30 seconds delay function. 8. quote sheet circuit: The tie piece of electronic circuits, improve the earthquake resistance, the circuit parameters are more stable and reliable. 9. Intelligent Diagnosis: electricity, meter circuit automatically detects the working condition is normal. Second, the Controller Specifications: Relay capacity: DPDT, rated 10A, 115Vac or 5A, 220Vac delay: 0 ~ 30 seconds continuously adjustable power supply: 220Vac or 24Vdc sensitivity: 0.1pF ~ 1000pF material temperature: -184 ℃ to 260 ℃ circuit temperature: -40 ℃ to 70 ℃ loss of power protection: the level of mode, field adjustable housing: IP65, heavy-duty cast aluminum housing with self-test function probe up to 1000 meters of cable between the stainless steel and Teflon controllers and sensor mounting Thread: 1 "NPT Probe material: stainless steel, Teflon wetted media: Stainless steel Electrical connection: PG11 or 3/4" NPT operating pressure and operating temperature relationship: 70Kg / Cm2 -184 ℃ 70Kg / Cm2 38 ℃ 31.5Kg / Cm2 149 ℃ 24.7Kg / Cm2 @ 205 ℃ 0Kg / Cm2 260 ℃.
