The digital pressure and level transmitters PIEZOMESS PZM / VARIMESS VRM - Series 100,
with their O-ring seals, are suitable for pressure and level
measurements without dead spaces, under strict cleanliness conditions,
as well as for viscous and crystallising media. They have a modular,
flush-mounted connection concept with various adaptors. An additional
temperature sensor as a secondary measuring element provides the
temperature measured on the sensor available on the display as
additional information.
The PIEZOMESS PZM / VARIMESS VRM - Series 100
consists of one basic device, which can be combined with various
application-specific adaptors, e.g. welding sockets, DRD, VARIVENT, DIN
11851, Clamp, Flange DIN, etc. In combination with the advantages of
digital electronics, e.g. a large measuring range and on-site
adjustability, this concept results in clearly reduced storage space and
spare parts and thus to a cost reduction in materials administration.
During operation, various pressure units can be shown on the local
display (OPUS), along with the sensor temperature as a secondary process
indicator. The display and operating module has either been integrated
into the field housing or is available as an external housing with a
plug connection. The sensor-specific data are stored in a reference data
memory and are made available to the microprocessor for evaluation
purposes.
The pressure sensors of the
PIEZOMESS PZM series work according to the piezo-resistive measuring
principle and are separated from the measuring material by a stainless
steel membrane. The pressure is transmitted via
an oil filling that is safe for use with food. All parts that come into
contact with the medium have been welded. The PIEZOMESS PZM type series has been specially designed for level measurements.
The pressure sensors of the VARIMESS VRM series are
robust and overload-protected ceramic membranes that work according to
the capacitive method. The pressure to be measured acts on the sensor
via the flush-mounted stainless steel membrane and the low-volume oil
supply to the sensor. The system has a high overload capacity due to its
special design. The type series VARIMESS VRM is intended for pressure
measurements, where pressure surges and cavitations are common.
