The continuous liquid level sensor is installed inside the primary and secondary storage tanks. The series continuous liquid level sensor is composed of two components connected in series through a low-temperature cable, and cooperates with the converter to output a nominal 0-5V voltage signal

Technical indicators (series of common parameters) Output signal: capacitance value The capacitance difference between two adjacent segments of the same sensor: not more than 0.2 pF; The difference of capacitance between odd and even array: 0.1 PF ~ 0.5 pF (C even-C odd); Accuracy: ± 2mm; Response time: s100ms; Each sensor has multiple segmented capacitance units, the interval between segmented units is 2mm, and the non-measurement length of the upper and lower ends is not more than 100mm; Temperature resistance: the sensor can work normally at the temperature of 80K ~ 500K; Pressure withstand performance: the sensor can work normally under the pressure of no more than 0.8 MPa; Medium compatibility requirements: adapt to methane and liquid oxygen, withstand medium for 72h; Conduction and insulation: On-resistance: The on-resistance between two leads of the same electrode and between the shield layer should be less than 2Ω; Insulation resistance: The insulation resistance between the internal electrode and odd and even electrodes, and between the cable core wire and the shield layer should not be less than 100MQ/100VDC; Product: s7Kg (cable length is 9m)
