TSU Series
TSU series galvanically isolated safety barriers are designed for connection to ON-OFF sensors (two wires) with current (5 mA / 13 mA ? 1 mA) or frequency (1,2 kHz / 3,8 kHz ? 0,2 kHz) output. Inputs are constantly monitored to reveal any possible wiring anomalies (such as short circuit, open circuit or dispersion to ground). The ON-OFF signals from the sensors are retransmitted to the output with the control signals separated for each channel. The presence of bicolor LED?s in input and output circuits allows to locally monitor the status of barrier and sensors. The small size of the housing and the presence of two channels per unit offer the possibility of a high density wiring on DIN rail 35mm.
T7L Series
T7L 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 + HART) with high repeatability and linear level indication independently from tank shape, 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. As option it is possible a PT100 installation in order to get the local temperature of the fluid.
T7B Series
Working system of T7B (level) and T7B (density) series transmitters is based on Archimede?s buoyancy principle. These instruments are designed for continuous measurement of level, interface and density of liquids in all industrial applications, offering very high reliability and robustness within a wide pressure and temperature range: -1?100 bar / -100?C ? +350?C.

T72 Submersible Level Series
T72 series includes submersible electronic level transmitters with 4 ÷ 20 mA output and HART® digital communication protocol for hydrostatic pressure sensing. Sensors are always calibrated individually together with their own seal. Configurations and adjustments can be made remotely using HART® protocol compatible communicators.
LSG Series
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 VALCOM? TSU400 barrier) in order to provide two constant current output values related to alarm thresholds (On=6mA / Off=14mA). Switch replacement can be done without dismantling instrument from the process and doesn?t need any recalibration. LSG can be used also in ON/OFF mode (simple connection).
LSG Series
LSG-02 is a float level switch designed for detecting bilge liquid level and for control the level of oily and salty waters 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. The switch is equipped with integral test lever that conforms to class rules without complicating installation. Switch replacement can be done without the need of any recalibration.

KRG Series
KRG series includes radar level transmitters. Using 26GHz microwaves†, the liquid reflect them back to the instrument. The travel time, proportional to the distance between the surface and the gauge, is processed by instrument electronic generating output signal. KRG instrument works in a non-contact and a non-mechanical way so: It has a least request of maintenance for long term; It can’t be damaged by the process liquid; It has a long durability;
BMS Series
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.
ASL Series
ASL instrument is designed for marine and on-land applications for liquid detection, pump control, water ingress alarm systems, overfilling protection on liquids with or without foam. ASL works on Valcom® proprietary principle of distributed acoustic waves in a metal rod. If the rod is not covered by the liquid the acoustic waves are dispersed freely without any interference. If liquid covers the rod the emission of acoustic waves is muffled and this interference is picked up by the piezoelectric sensor and converted into an on-off signal. These instruments have no moving parts, no vibration, no optical or capacitive detectors. They are pure static instruments offering the maximum reliability.
27L Series
27L 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 shape, 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. As option it is possible a PT100 installation in order to get the local temperature of the fluid.
