FLOWT OPERATED LEVEL TRANSMITTER
|
|
'CRISTAL' Float-operated level Transmiter is used for
contInuous level Indication and Control of any liquid.
This consists of a level transducer and a signal
converter. This can be used for any liquid chemically
compatible with transducer material, unaffected by
electrical conductivity. temperaturc, pressure or
viscosity.
The transducer consists of a float and guide tube
assembly in non-magnetic material to achievc undisturbed
flux. A chain of closely spaced glass encapsulated reed
switches and electric resistors are placed inside guide
tube. According to level rise and fall, the float moves
and actuates the reed switch in the chain through a
magnet system within it and develops a proportional
voltage. The operation is similar to a sliding
resistance potentiometer. The sensed voltage is fed to a
transmitter for converting it to a signal of 0 - 20 m.-\
or -1 - 20 mA. The transmitter can be incorporated with
a dibrital display and or / adjustable multirle alann
rdays.
The transducer can be mounted internally or externally
through a chamber by flanged connection of y' 0:8 or 4"
!\iB. The tran<:ducer is pre-calibrated in the fa~:ory.
To operate the level tTansducer, it has to \\ork in
conjunction with a signal converter, which could have
!lI1e or 100IJ powered electronics. L!!'1f..'
r'('\,.'errd transmitter can be incorporating with a
digital display. Loop powered transmitter is used for
rcn:otc signaling to a process indicator/controller.
ll1e outstanding features of this transmitter arc, it is
pre-calibrated at factory, 4 - 20 rnA processed output
signal, 2 or 4 wire units, liquid level or liquid/liquid
interface detection: high accuracy and repeatability and
adjustable multiple alann relays.
The level transmitter can be supplied to any range up to
4 Mts. With flanged connection. Material of construction
will be nonnally SS-316 & suitable for max. temp of 1500
C. and pressure 15 Kg//cm2.
Enclosure protection will be weather-proof or flame
proof.
Spiral converter will have normal output 4-20mA
(OptioNED 0-20 o 0I - 0 - 5 VDC) max. load -100 ohms.
supply voltage of 24 V DC / 110 or 220 V AC. Digitai
display (optional) of 3 1/2 / 4 1/2 digits in 0% or in
cms. Control (optional) of multiple. stepless
adjustable: OF relays rated for 6A at 240 V AC.Mounting
can be panel or wall and enclosure protection of weather
proof.
