The high-precision and robust
level sensor is designed to provide continuous gauging
of liquid media levels in
tanks. The measuring principle used by the sensor exploits
the physical effect of
magnetostriction and is largely unaffected by temperature.
Magnetostriction is
particularly ideal where level measurements are required to be
extremely accurate, e.g. in
the chemical industry. The level sensor outputs measuring
signals in the range 4 to 20
mA. Available in lengths of 8? to 157? (200 to 6,000 mm),
it is compatible with a
variety of tank dimensions. It also comes in the following
versions:
The explosion-proof version of
the level sensor can be installed in potentially explosive
atmospheres in which
electrical equipment of category 1 (zone 0) or category 1/2
(zone 0/1) are required.
Operating on the digital HART protocol, the HART level sensor
is able to output the position
of the first, second or both floats.
