VEGAPULS 43 – Profibus PA

Product description

With standard flanges of DN 50 to DN 150,
ANSI 2“ to ANSI 6“ or G 1½ A and 1½“ NPT,
the sensor antenna systems can be adapted
to various products and measuring environ-
ments.

The high-quality materials can also withstand
extreme chemical and physical conditions.
The sensors deliver stable, reproducible
analogue or digital level signals with reliability
and precision.

Continuous and reliable

Unaffected by temperature, pressure and
atmosphere content, VEGAPULS radar sen-
sors are used for quick and reliable continu-
ous level measurement of widely varying
products.
