FineTek EB 2600 Operation Manual

EB 2600 COMPACT CAPACITANCE
LEVEL TRANSMITTER
OPERATION MANUAL
Thank for buying FineTek's products.
Please read the user manual first before
using it. It is important to be familiar with
product's performance and function. Please
keep the user manual for operation refereuce.
WORKING PRINCIPLE
The level measurement of a medium in a tank is accomplished
by capacitance theory. The tank wall,
the sensing probe and the medium are all capacitors. A high
frequency since wave is applied between the probe and the
tank wall. The level change of the medium will cons equently
change the current of the applied since wave, forming a
proportional relationship between medium level and output.

WIRING AND CAUTION
2 After installation of the Compact Capacitance LevelTransmitter on
the top of tank, please make sure the cover of the transmitter is
contacted with tank perfectly. Please avoid the grounding of panel
meter to touch the tank wall.
2 While the panel meter is not supplied with a power supply, please
prepare a 24V power supply for use. The wiring for panel meter is
showing in diagram 1.
2 The max cable length is depending on the max resistance.
Maximum resistance is not to exceed (Vs-15)H50W to
maintain the accuracy of measurement.
2 Make sure to separate the signal cable with other big power
cables (such as pump, conveyer and solenoid valve)while wiring.
Before turning on power, make sure all wirings are correct.
2 Connect isolation cable with GND of power.
2 Connect tank with heater or cover of electric device to decrease EMI.
