NYSP-L863 (High Temperature Type) RF Admittance Switch
Rf admittance switch is also often called rf admittance level meter or RF admittance level meter. Rf admittance is a new level control technology developed from capacitive, which is more reliable, more accurate and more widely applicable. It is an upgrade of capacitive level technology. So-called rf admittance, the meaning of the admittance to the reciprocal of electrical impedance in, its element by resistive, capacitive component, the perceptual component integrated, and radio frequency or high frequency radio spectrum, so the radio frequency admittance can be understood as admittance is measured with a high frequency radio waves. When the instrument is working, the sensor of the instrument forms the admittance value with the tank wall and the measured medium. When the level changes, the admittance value changes accordingly. The circuit unit converts the measured admittance value into the level signal output to realize the level measurement.

※ Note: Products can be customized according to the specific
requirements of users!
Before connecting RF admittance level switch, make sure that the
instrument and power supply are consistent (e. G. 220VAC instrument
and 220VAC power supply).
A .Line power supply type (115VA.C or 230VA..C) Ac power line
connection: fire line (H), mid line (N) and ground wire (G), if the
wire does not have the standard black, white, green three colors,
be careful not to confuse the lead. Note: ground must be grounded.
B .DC power supply (24VD.C)
24VDC Power line wire connection: the original (H) end is -24V (+),
the original (N) end is the common end (-) and the original (G) end
is still the ground wire (G), Note: must be groxinded.
C .Connection of control relay
NYSP Type A relay output contact is type C,two groups of double
pole double throw, 10 A,115VA.C, impedance. Light low inductance
load can be used for solenoid valve or alarm. Heavy inductance
loads must be driven by intermediate relays. The following figure
shows the three common connection modes of point level control
functions.
