Point Level Switches in India | Level Transmitter

1

Trumen vibrating rod point Level switch model LSVR Trumen came into existence in 2009 and initially
suitable for solids and powder containing fine- started with manufacturing of Tuning Fork Level
grained and non-fluidized bulk solids. Switches for liquid and solid applications. With time, the manufacturing range increased with addition of
Trumen vibrating rod is a single element tuned Capacitance Level Transmitter Capacitance Level
mechanical level sensing device. Suitable for a wide Switches, RF Admittance Level Switches, Rotating
range of applications. Paddle Level Switches, Conductivity Type Level Switches, Vibrating Rod Level Switches, Hydrostatic Level Transmitter, Radar.

APPLICATION_ Trumen vibrating rod is used in
different applications like- v Free flowing
solids, powder, fly ash, clinker, cement, salt,
calcium carbonate, sand etc Please note granuals
size should not be more than 25mm. v Process
temperature maximum 200 / 250 C (available on
requirement). v Operating pressure 15 bar
maximum. v Minimum bulk density less than
(350gm/litre).
OPERATING PRINCIPLE
Electronics of LSV-R excites the
piezo-electric-crystals inside the tuning rod,
which makes the rod vibrate at its natural
resonance frequency in free air.
Amplitudes of vibration are above threshold when
rod is free to vibrate.
When Material touches the rod, vibration stops as
resonance gets disturbed.
Amplitude of vibration as sensed by the
electronics falls below the threshold, Materials
presence is thus detected by observing the
amplitude of vibration.

OPERATION
Device operation and settings
Trumen vibrating rod Level switch is very easy to
operate-
1. Open the cover of Trumen LSVR and you can
see there are 9 terminals. Terminal 1,
2 3 are for auxiliary power supply. Terminal 4,
5, 6 7, 8, 9 are for relay output.
2. Connect the power supply either 15 to 80VDC
or 15 to 260VAC on terminal 1 2 and switch on
the power.
3. Trumen vibrating rod Level sensor starts
vibrating in air. power LED is in on and status
LED is in OFF conditon.
4. Now we fill the material solids, granuals
or powder up-to the rod level.
5. You can see the status LED of LSVR is on
means material reaches to the high level.
6. Now we empty the material, you can see the
status LED is off means material goes below the
sensor.
7. Relay status also change fron NC to NO.
8. There are 4 DIP switches provided on
connection panel. Via DIP switch no. 1 we can set
the sensitivity that means if the material is
fluffy in nature or having Low bulk density (less
than 350gm/litre) we need to ON switch no.l. In
this condition LSVR will sense the material. Keep
it turned off for normal density (more than
350gm/litre) materials.
9. Switch no. 2 is to set dry delay means off
delay. On the DIP switch no.2 and empty the
material. LSVR will wait for 5sec once the
material goes below the sensor and after 5 sec it
generate switching.
10. Switch no. 3 is to set wet delay means on
delay. On the DIP switch no.3 and fill the
material. LSVR will wait for 5sec once the
material touches the sensor and after 5 sec it
generate switching.
11. Switch no. 4 is to set fail safe means the
instruments should be in alarm condition if the
sensor facess power failure. When the sensor is
installed for high level keep the DIP switch no.4
is turn off, failsafe high or maximum and when
the sensor is installed for low level keep the
DIP switch no.4 turn on, failsafe low or minimum.
12. You can easily replace the electronics as
shown.
