2 General information
The level measuring instrument VEGAPULS PS61(*).C****P/K/F/L**** is based on radar technology
and is used to detect the distance between product surface and sensor by means of high frequency
electromagnetic waves in the GHz range. The electronics uses the running time of the signals
reflected by the product surface to calculate the distance to the product surface.
The VEGAPULS PS61(*).C****P/K/F/L**** consist of an electronics housing, a process connection
element and a sensor (the antenna). As an option the display and adjustment module can also be
integrated.
The measured products can also be combustible liquids, gases, mist or vapour.
The VEGAPULS PS61(*).C****P/K/F/L**** are suitable for use in hazardous atmospheres of all
combustible materials of explosion group IIA, IIB and IIC for applications requiring instruments of
category 1G, category 1/2G or category 2G.
If the VEGAPULS PS61(*).C****P/K/F/L**** are installed and operated in hazardous areas, the gen
-
eral Ex installation regulations EN 60079-14 as well as these safety instructions must be observed.
The operating instructions as well as the installation regulations or standards that apply for explo -
sion protection of electrical systems must generally be observed.
The installation of explosion-endangered systems must always be carried out by qualified person -
nel.
Category 1G instruments
The VEGAPULS PS61(*).C****P/K/F/L**** are installed in hazardous areas requiring an instrument
of category 1G.
Category 1/2G instruments
The electronics housing is installed in hazardous areas requiring instruments of category 2G. The
process connection element is installed in the separating wall, which separates areas requiring in-
struments of category 2G or 1G. The antenna system with the mechanical fixing element is installed
in hazardous areas requiring instruments of category 1G.
Category 2G instruments
The VEGAPULS PS61(*).C****P/K/F/L**** are installed in hazardous areas requiring an instrument
of category 2G.
