Tival Sensors TS-RFK Float Level SwitchIndonesia Industrial Parts

Overview

The company TIVAL Sensors GmbH was established in 2005 by Dipl.-Ing. Hartmut Linde. Competence in service, a high grade of quality, short delivery times, and a fair partnership with our customers and vendors are our corporate goals.

We started with mechanical pressure switches. The family of FF4 pressure switches stands for an extraordinarily good and sturdy quality product within the scope of our product range. Following the technical advancement and the development of the markets, the focus on automation technology was shifted to electronic components.

One of our keys focuses is on products related to and used in water applications. These are i.e. pressure transducers with contact outputs; so-called electronic pressure switches, as well as pressure transmitters providing analog output signals.

Equipment for level monitoring and level measurement make up a large part of our portfolio. The program is complemented by products for flow- and temperature-measurement, soft starters (i.e. for pump applications), digital readouts, isolating switch amplifiers, and many more.

International approvals for special applications, i.e for explosion-endangered environments (pressure, temperature, level), for marine and offshore use (pressure, temperature, level), and applications in fire protection equipment (VdS, sprinkler systems) are available.

Our Team of experienced technical and sales staff members serves the customers individually and timely, the well-assorted stock enables short delivery times. Also, products important for innovative industries are available from stock.

The huge worldwide agreement for our products and the fast service provided is what drives us. We are constantly enlarging our portfolio to also fulfill our customer’s future needs and to carry on with offering a wide range of products and services.

Description

The float switch TS-RFK is designed for continuous measurement of fill levels of liquids. The system uses a magnetic float that slides via a guide tube that contains a chain of reed contacts. The reed contacts are arranged in series. When sliding across the reed contacts the float switches each contact on or off. In this way, the total resistance of the chain of reed contacts is increased or decreased. The current resistance value of the measuring

chain is the output signal that can be evaluated by an appropriate control as a level value. A measurement transducer, which converts the current resistance value into a 4 … 20 mA analog output, can be integrated in the guide tube optionally.

Tival Sensors TS-RFK Float Switch, Level probe with reed contacts. The float switch TS-RFK is used for the continuous measurement of the liquid level. The system uses a magnetic float that slides over a standpipe containing a reed contact chain. When driving over the reed contacts, the float switches the individual reed contacts arranged in series on or off and increases or decreases the total resistance of the measuring chain.

The current resistance value of the measuring chain can be evaluated by a corresponding controller input into the current level. Optionally, a transducer can be integrated into the sliding tube, which converts the resistance value into a 4 … 20 mA analog output signal.
