The SL conductive probe series provides a solution for controlling the level of liquid with a minimum value of conductivity of 1µs.

The probes are available in a wide variety of materials and process connections and are of construction appropriate to operation in extreme conditions such as those found on industrial plants.

The visual level indicators ILC series are used to visually monitor the status of the level of liquids in tanks, and are equipped with a minimum or maximum level switch. The indicators are mounted outside the tank by means of threaded connections. The system thus designed allows the vision of the level inside the tank at 360°.

Level measurement with capacitive technology.

The liquid to be monitored must have a minimum conductivity of 50 µS / cm and must not be adherent to the probe.

All programming functions can be managed from the keypad on the front panel of the instrument. Level status is displayed on the LCD. The analog signal is proportional to the measured level, and can be calibrated according to the geometry of the tank. The absence of moving parts offers a system that does not require particular maintenance

Measuring ranges 100 … 3000 mm

Programming via the front panel keypad and LCD display

0-10 V or 4-20mA analog output

Measuring units programmable in linear values or %.

The optical sensors, SLO series, are a valid solution for level control of liquids, even for applications in small tanks. The optical sensor is located in a metallic body which includes a polysulfone prism inside of which there is inserted an infrared transceiver. As soon as the sensor is immersed in the liquid, the refraction index of the prism is changed and a large part of the infrared beam is dispersed in the liquid, causing the output to change state. The sensor is particularly suitable to be side mounted for control of translucent liquids even coloured.

No moving parts

Hermetic construction, sealed electronics

Minimum protection degree IP65

This universal signal processor was designed as interface for continuous level sensors with potentiometric output (LC series). Subsequently evolved until the current version that can be interfaced with any sensor or signal transmitter. This electronic unit handles standard industrial signals 0-5V, 0-10V, 0-20mA, 4-20mA, frequency and potentiometers.

Magnetostrictive continuous level transmitters base their operation on the physical principle called Wiedemann effect and it allows continuous and precise measurement of liquid levels. The electronic unit sends a pulse within a waveguide contained in the measuring rod; the magnetic float intercepts the pulse generating an echo that is detected by the same electronic unit. The elapsing time between the emission of the pulse and its recognition is directly proportional to the position of the float, and then to the value of the level to be measured.

The principle operation of the LCD-S level switch is based on the moderate shutdown of a series of resistors and reed contacts. These are placed inside the guiding rod by a magnetic float. The only moving parts will be the float which moves along the measuring rod. You can program the sensor manually or via the “MYVALCO” app using NFC technology, available on Android® app store.
