Application-Specific Integrated Circuit is an integrated circuit (IC) customized for a particular
use, rather than intended for general-purpose use.
Electromagnetic compatibility (EMC) is the branch of electrical sciences which studies the
unintentional generation, propagation and reception of electromagnetic energy with
reference to the unwanted effects (Electromagnetic Interference, or EMI) that such energy
may induce. The goal of EMC is the correct operation, in the same electromagnetic
environment, of different equipment which use electromagnetic phenomena, and the
avoidance of any interference effects.
An IP (Ingress Protection) number is used to specify the environmental protection of
enclosures around electronic equipment. These ratings are determined by specific tests. The
IP number is composed of two numbers, the first referring to the protection against solid
objects and the second against liquids. The higher the number, the better the protection. For
example, in IP67 the first Number (6) means that the device is totally protected against dust,
and the second (7) that it is protected against the effect of immersion between 15cm and 1m
The Pressure Equipment Directive (97/23/EC) is the legislative framework on European level
for equipment subject to a pressure hazard. It was adopted by the European Parliament and
the European Council in May 1997 and has been obligatory throughout the European Union
since May 2002.
All sensor related settings/data saved on an EPROM. SENSORPROM technology
automatically configures the transmitter at start up providing calibration data, pipe size,
sensor type, and output settings. The SENSORPROM automatically stores values or
settings changed by users, and automatically re-programs any new transmitter without loss
of accuracy.
USM II is a Communication Platform. The Siemens USM II concept enables fitting of add-on
bus modules without loss of functionality:
1. All modules can be fitted as true "plug & play"
2. Module and transmitter are automatically configured through the SENSORPROM
