I.Description:
LRSP series rf admittance level switch is a kind of new type level meter, it is developed from the capacitive level meter, it is more reliable,more accurate,broader application and hanging proof applicability.It thoroughly solved the material adhesion problem,has higher system stability compared to other similar products.Even can work reliable at the scene of the extreme bad conditions.Can be widely used in power plants, metallurgy,cement, food and other industries with the reliable performance and easy installation.
II.Features:
*Widely use: measure liquid level and material level, satisfy the measurement requirements of different temperature, pressure, medium, and can be applied to corrosion,impact situations etc.
*Prevent hanging materials: unique circuit design and sensor structure, can make its measurement is not affected by sensor hanging materials, no regular cleaning, avoid mistake measurement .
*No maintenance: no moving parts, no mechanical parts damage problem, no need to maintenance.
*Anti-interference: non-contact measurement, strong anti-interference ability, can overcome the steam, foam and mixing effect on the measurement.
*Anti-interference:Contact measurement, strong anti-interference ability, can overcome the steam, foam and mixing effect on the measurement.
*Accurate and reliable: Measurement of diversification, makes the measurement more accurate, high stability, long service life.
III.Performance indicators:
*Power supply: 20VAC 、20VDC optional

Ⅳ.Installation instructions:
1.Rf admittance level meter can be installed in vertical and horizontal
2.When install the instrument, must guarantee that the center of the sensor handgrip and shielding layer and vessel wall (or installation pipe) out of touch, good insulation
3.Install screw firm connected to the container, good electrical contact. And formation of the probe must enter inside the container. For large range or mixing situation,probe need support or ground anchor is fixed, but the fixed end must insulation with the probe.
4.The inlet wire button of horizontal installation instrument must be downward, vertical inlet wire explosion-proof pipe installation must be lower than the drain of inlet, in case of explosion-proof pipe water-logged endanger electronic unit of the instrument.
5.Instrument installation area requires the lightning protection device, in case of a lightning stroke.
6.Power supply ground wire connected to the standard ground or standard instrument ground, cann’t connected to the power ground.Cable through region requires the lightning protection device, in case of a lightning stroke
