HART® protocol signals. This system allows a continuous level
measurement with high repeatability.
Reed chain replacement can be done without dismantling the
transmitter from the process and doesn’t need any recalibration.
27L 27LG series includes Float Reed level transmitters. Inside
the float
is placed a toroidal magnet which drives, without contact, Reed
contacts located inside the guide pipe. Moving along the guide
pipe
the float changes the reed contact status. These variations are
then
acquired by the electronic board and converted into a current
signal.
This system enable a continuous level measurement (output 4÷20
mA) with high repeatability and linear level indication independently
from tank shap, or allows to realize on-off controls by using
two
floats (output On-Off 5÷15 mA). Reed chain replacement
can be
done without dismantling the transmitter from the process and
doesn’t need any recalibration.
RMG

T7SG
T7SG series includes transmitters for continuous specific gravity
measurement in liquid, mud, cement slurry, etc, manufactured
using
two seals placed at a fixed distance and connected through capillaries
to a DP cell. The instrument gives the specific gravity value
of
the product by measuring the hydrostatic pressure between the two
seals (Dp) and applying the formula SG=Dp/d where “SG” is
the specific gravity, “Dp” is the differential
pressure and “d” is the distance between the two
seals. T7SG series transmitters are manufactured with an especially
heavy duty mechanical construction and allows signal output
both in analogical 4÷20 mA and digital HART® protocol
form. T7SG series transmitters are used in all industry branches
for continuous specific gravity measurement of liquids in tanks.
ASL400
ASL400 is designed for marine and on-land applications for liquid
detection, pump control, water ingress alarm systems, for high
and
low alarm level, overfilling protection on liquids with or without
foam. ASL400 works on the principle of distributed acoustic
waves
in a metal rod. If the rod is not covered by the liquid the sound
waves are dispersed freely without any interference. If liquid
covers
the rod the emission of sound waves is muffled and this interference
is picked up by the piezoelectric sensor and converted into
a current
signal in the current loop (on-off). These instruments have no
moving parts, no vibration, no optical or capacitive detectors.
They are
pure static sensors offering the maximum reliability.
LSG
LSG is a float level switch designed for liquid level control
in marine and
industrial fields.
Typical applications are high and overfilling protection, water
presence
detection, high and low alarm level of liquids with or without
foam.
Inside the float is placed a toroidal magnet which drives, without
contact, a
switch located inside the guide pipe; instrument have to be supplied
with a
constant voltage of 24Vdc (for example by means of TSU400FM barrier)
in
order to provide two constant current output values related to
alarm
thresholds (On=5mA / Off=13mA). Switch replacement can be done
without dismantling instrument from the process and doesn’t
need any
recalibration.
TSU400
The galvanically isolated safety barriers TSU400 are valid alternative
to passive barriers because they don’t need a high integrity
I.S. ground, being the isolation between the safe area and
the hazardous area guaranteed by a transformer. TSU400 series
barriers have an intrinsic voltage regulation of the supply
and are designed for connection to ON-OFF sensors having a
mA output so that they permit to interface 5/13 mA two wire
switching instruments also giving a relay output. They are
especially suitable for ships applications and for hazardous
areas installations being certified [EEx ia] IIC. Great advantages
are offered by the use of TSU400 series barriers interfaced
with Valcom® ultrasonic level switches ASL400 series.
BMS BMS is a bubbling system for level detection based on the
measurement of hydrostatic pressure caused by the liquid contained
in the tank. The working principle is founded on the measure of
the
pressure value needed to maintain a constant and regular air flow
through a pipe probe open in the bottom and submerged into the
liquid. At any level variation of the liquid in the tank corresponds
a
variation of the hydrostatic pressure applied on the air outgoing
from
the probe pipe; these pressure variations are precisely detected
by
the 27M P/I converter and converted into a standard 4÷20
mA
electric signal. PR3 regulator keeps constant bubbling air flow
at
any level value, assuring high precision measurement.
