Danger; Application And Scope Of Use - TC KEMA 04ATEX1232 X Betriebsanleitung

Danger!

There is a risk of poisoning or suffocation when working in containers. Relevant
personal protection measures (e.g. respiratory devices, protective clothing, etc.)
must be taken before work is carried out.
Danger, risk of explosion!
An explosive atmosphere may develop in a container. Measures must be taken to prevent
sparking. Work in such areas must be done by qualified personnel in accordance with the
relevant safety regulations and guidelines.

Application and scope of use

An approval has been issued for KTX125... or KTX Level Transmitters ... as defined in EC
Directive 94/9/EC (equipment and protective systems for use in potentially explosive
atmospheres).
The technical data in these operating instructions must be complied with.
When using KTX125... or KTX level transmitters please observe the mounting and operating
instructions of other system components (e.g. Magnetic level gauge).

Structure and functional description
KTX125... and KTX Level Transmitters... (in connection with a magnetic level gauge and
float) serve the purpose of monitoring liquid levels in containers. These media must not
possess any extreme form of soiling or coarse particles and must not tend toward crystallisation.
In connection with a control unit or an analysis unit, these Transmitters form a filling level
measuring system.
The Transmitters function according to the float principle with magnetic transmission in three-wire
potentiometer circuitry or two-wire resistance circuitry. A reed measuring chain (reed contacts +
resistors) installed in the transmitter tube is actuated by a permanent magnet installed in the float.
This provides a height-proportional resistance signal.
The KTX Transmitter can also be used as part of a position measuring system. The
transmitter is then installed in or mounted on a machine or equipment system. Together with a
control unit or an analysis unit, this combination then forms a position measuring system. The KTX
Transmitters function with magnetic transmission in three-wire potentiometer circuits or two-wire
resistance circuits. A reed measuring chain (reed contacts + resistors) installed in the KTX... tube
is actuated by a permanent magnet installed in or mounted on the machine or equipment system.
This provides a resistance signal proportional to the position.
Information on the design variants is available by referring to the type code on Page 11.
