15.Rotary Paddle Level Switch-SE Series

Principle

The
SE series operating principle is simple. A unit is usually located
through a bin wall at the top, middle or low level of a bin. During
normal operation (no material present) a synchronous motor rotates the
paddle at 1 RPM. When this paddle rotation is impeded by material,
surrounding the paddle, motor will stall and cause the Micro-switch to change state. (indicating an alarm or control)

Features

Airtight sealing device, outdoor application is available.

Unique
sealing ring design, it can perform good dust protection to avoid the
dust permeate into housing body along with the shaft.

The torque force is adjustable.

The performance of torsion is stable and reliable.

If the rotary paddle bears an extra overload, the motor will be appeared slide to prevent the inside mechanism damaged.

It
is rationally designed, the inside mechanisms are easily tore down for
checking, maintenance and replacement. It doesn”t necessary to remove
the complete set from the tank.

16. Capacitance Level Switch-SA Series

Principle

The
capacitance level sensor measuring principle is base on the ”
capacitance effects ” , when this level sensor is set on a silo, it will
be formed a condenser between the detector electrode and the silo wall.
The capacitance of this condenser varies proportional to the change of
material specific inductivity ( DK value) of the material stored in the
silo , when the more material substances increased in the silo, the more
capacitance value added simultaneously, then it will let his interior
circuit “s resonant signal to create a bigger amplitude ,and such a
signal amplitude become more or less than factory default threshold
value, the relay device will be energized.

Features

No moving parts inside the device, it will be not affected by friction, which are suitable for powder or liquid application.

Various models are suitable for different application.

17. Vibrating Probe Level Switch-SC Series

Principle

The
vibrating probe of level switch operated by using two piezoelectric
elements built-in on vibration tube. The first piezoelectric element
triggered by pulse signal that created from circuit to transport
vibration energy out, and the other piezoelectric element receives the
vibration and transmits it to output electric signal. While the probe
contacts material, the detection signal will be decayed and the
vibration will hold and send out the relay on.
Vibrating probe of
level switch provides reliable & maintenance-free for bulk solids.

18. RF-Capacitance/ Admittance Level Switch-SB Series

Principle

In
order to eliminate false alarm given due to medium with high viscosity
sticking onto the probe , a special material acting as an insulation
electrode have been added in between the active section and the
grounding section.
As shown in the diagram, sensing probe always
experience medium clogging on it and thereby produces a capacitance and
resistance between the 3 parts. Since the electric field between the
active section and the guard section is round shaped, there will be no
current passing through the medium between the electrodes.
The
Admittance level switch uses this principle, to add a guard section
between the active section and the grounding section to block the
admittance current to reach the vessel wall from the medium between the
active section and grounded electrode. Although there would be a small
amount of admittance current between the guard section and the active
section, the circuit would not take this current value into account. Due
to the guard section, only the admittance current change between the
active section and the tank wall will be detected by the circuit, thus
only when the sensing probe is in contact with the medium will there be a
precise signal.

Z=1/2pfc, when the capacitance in the vessel increase, impedance will
decrease and current will increase. Vice-versa, when the capacitance in
the vessel is small, the impedance will increase and current will
decrease accordingly.

2.Magnetic Float Level Switch-FC/FD Series

Principle

The
single unit or multiple reed switch units arehoused tightly in
stainless steel or engineeringplastic stem, and the permanent magnet
issealed into the middle of the specified float ball(s). You can mount
the float ball to penetrating through the stem, then the liquid buoyancy
will deliver the float ball up and down at the specified position by
graduating rings.
When the float internal magnet approaches the reed
switch, it will actuate the reed switch contact point to create an open
or close circuit. We can apply such on-off output signals to reach
liquid level controlling and monitoring purpose.

of acidity and alkalinity liquid, solvents or oil fuels.

The
reed switch and lead wire are isolated absolutely with liquids. All
stainless steel switches are applicable to high pressure andhigh
temperature performances.

3. Side Mounting Float Switch-FF Series

Principle

Simple
theory as liquid buoyancy is utilized for the main principle of this
“FF” series. A change of liquid level correspondingly travels the float
to extreme levels up and down. The reed switch is thus “NC” and “NO”
exchanged as well as the permanent magnet on pivot will have mutual
repellence to the other one inside on the housing for like poles, which
the Microswitch is button-pushed by magnet to states “NO” and “NC”
exchanging likewise.

5.Thermal Dispersion Flow Switch-SP Series

Principle

The
Thermal Flow Switch Monitor is based on the principle of thermal
dispersion. A typical configuration uses two Temperature Detectors set
within the tip of the sensor. One Temperature Detector is heated a few
degrees above the other one. As the process medium flows over the tip of
the sensor it disperses some of the heat from the heated Temperature
Detector. The delta temperature is a function of flow velocity and
converted into electronic signal. The open collector changes state once
the set point has been reached.

Features

Detection of flow velocities in pipes

LED functions Display

Open collector alarm output

Measuring Range:(Speed)
water: 1~150 cm/s

Material SUS304, 316, PVDF, PP, available

6. PaddleType Level Switch-SF Series

Principle

Flow
Switch utilizes the force of liquid flow to propel its paddle in order
to detect the incoming flow or moving of the existing liquid in pipe. In
condition of static liquid or no liquid, the spring is in expanding and
press the magnet downward vertically. Reed switch contact is N.O.
As
flow occurs and the paddle is thrusted and raised at an upward angle of
20°~30° (or more), the eccentric of paddle will push the magnet upward
to actuate the reed switch which is thus in a close circuit. The length
of paddle can be adjusted with the diameter of a pipe.

7. Optical Level Switch-SD Series

Principle

Refraction
index of plastic and air varies in big range. Infrared light can be
easily reflected totally between plastic and air. In contrast, infrared
light would totally penetrate through plastic while plastic and liquid
are taken place. Optical switch operates
by sensing the difference
of refraction index between various mediums, which causes different
degree of refraction and penetration.
When dry, the transmitted
light is reflected by the prism back to the receiver. When the sensor
is wetted in liquid, only part of the transmitted light would be
reflected back to the receiver while most is lost into the liquid. The
received light then changes the signal and controls the switching
accordingly.
Optical switch is equipped with infrared source and
receiver. They are to detect and verify the status of infrared light
reflection and penetration between the mediums in order to trigger the
alarm output.

9. Pressure Level Transmitter-EC Serie

Principle

A
pressure sensor is made out a piezoresister Wheatstone bridge. The
pressure is applied to the diaphragm and passes through the silicon oil
onto the Wheatstone bridge. When the pressure acts directly on the front
face of diaphragm, the Wheatstone bridge will create a different
voltage. This voltage difference can then be amplified to obtain a
current signal of 4-20mA. After connecting this current output to a
meter, we can scale the meter to read the level of the applied liquid in
a container or a vessel.
