Product lines: level sensors and level switchesIn order to get a precise level measurement in a wide range of different application, it’s possible to choose betwe-en different measurement systems as reed contact, conductive or optoelectronic.The level sensors or level switches are also available in different materials as stainless steel, PP, PVFD, PVC or brass, in order to satisfy requirements of every industrial applications.

Level sensor - TFCThe principle of operation is of potentiometric type, based on the gra-dual shutdown of a chain of resistors and reed contacts, placed inside the guiding rod, by a magnetic float. An analogue output signal in pro-vided with a measuring resolution of 5, 10 or 20mm.

Level switch - TFSThe principle of operation of these instruments is based on the drive of one or more magnetic reed contacts, placed inside of the measuring rod, by one or more floats. Up to 6 floats with individual switchpoints are available for comprehensive monitoring of the liquid level.

Optical level - TOSThe optical sensor is located in a metallic body which includes a poly-sulfone 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 changes and a large part of the infrared beam is dispersed in the liquid, causing the output to change state.

Conductive level - TCSConductive probes constitute a valid solution for controlling the level of liquid with minimum value of conductivity of 5µS/cm.The resistance between two measuring electrodes changes by the presence or absence of a medium. In single-rod probes, the electrically conductive tank wall serves as a counter electrode.

Level switch with display – DLFThe DLF 8980 is the ideal combination of a float level and transmitter with display.The parameters are set on the device or in a timesaving way via an NFC - smartphone App. The settings in combination with a comprehensive set of options make the DLF 8980 suitable for a wide range of industrial applications. The magnetic float which activates reed contacts inside the guiding rod provides a measuring resolution of 5, 10 or 20mm.

Product lines: level sensors and level switchesIn order to get a precise level measurement in a wide range of different application, it’s possible to choose betwe-en different measurement systems as capacitive, ultrasonic and High-frequency level sensor.

Capacitive Level MetersThe capacitive level meters are intended for continuous level measurement of liquid and bulk solids in tanks, vessels, sumps or silos, hoppers etc. They are comprised of a housing with electronic module and measuring electrodes. The electronic part converts the size of the capacity to the current signal (4 ... 20 mA) or voltage signal (0 ... 10 V). Level meters are made in several modifications of measuring electrodes (rod and rope). The electrodes can be covered by an insu-lating coating in case level measurement of adhesive, aggressive or electrically conductive media. Rod electrodes are also available in a version with reference (coaxial) tube for level measurement of liquids in tanks made from non-conducti-ve material.

Ultrasonic Level MetersThe ultrasonic level meters are compact measurement devices containing an ul-trasonic transmitter and an electronic module. Using an transmitter, level meters transmit the series of ultrasonic pulses that spread towards the level surface. The transmitter recuperates reflected acoustic waves that are subsequently processed in the electronic module. Based on the period during which the individual pulses spread towards the level and back, this period is averaged by the electronics that performs temperature compensation and subsequently a conversion to an output current 4 -20 mA, voltage 0 - 10 V or output RS-485 Modbus.

Capacitive Level Switch Capacitive level sensors are designed for limit sensing of the level of liquid and bulk solids in tanks, sumps, tubes or, hoppers, silos, etc. The sensors are ma-nufactured in several modifications of sensing electrodes (rod and rope). The electrodes can be given an insulating coating, a useful feature in case of adhesi-ve, aggressive or conductive media sensing. Rod electrodes are also available in a version with reference tube for measuring fluids in tanks made from non-con-ductive material.

Ultrasonic Level Switch The ultrasonic level sensor are compact measurement devices contai-ning an ultrasonic transmitter and an electronic module. Using an tran-smitter, level sensor transmit the series of ultrasonic pulses that spread towards the level surface. The transmitter receives reflected acoustic wa-ves that are subsequently processed in the electronic module. Based on the period during which the individual pulses spread towards the level and back, this period is averaged by the electronics that performs tem-perature compensation and subsequently a conversion to an output. The output of the ULS sensor consists of a PNP transistor with an open collector or a two-state current switch 4 mA / 20 mA.

High-frequency level sensorThe high-frequency level sensor is designed for industrial use for limit sensing of the level of liguid and paste-like media. The high-frequency level sensor may be a direct replacement of a vibrating level sensor, or of a capacity level sensor in case of more demanding applications. The media may be electrically conductive or non-conductive with any permittivity. It can be installed in metal or plastic tanks, pipes, filling tanks, sumps, etc. It is mainly designed for mounting into the wall of a tank or pipe, in which the actual detection of the level will take pla-ce. The sensor works in the high frequency band, enabling reliable de-tection of the level of media, and eliminating deposits or foam on the electrode. The sensor suppresses the influence of deposits of viscous media (ketchup, yoghurt, pastes, syrups, jams and jellies, creams, soap) as well as electrically conductive adhesive products (detergents, alkalis, chemicals).
