Due to the device construction with
measuring ranges from 1 bar to 600
bar (gauge, adjustable), process
temperatures from –25°C to +100°C,
process materials Al2O3-ceramic /
CrNi-steel as well as the availability
of industrial standard process
connections like thread ISO 228-1, EN
837 manometer, thread ISO 228-1,
DIN EN ISO 1179-2 E or thread metric
resp. ANSI NPT the device is especially
suitable for the use for machinery and
plant engineering, air-conditioning
and refrigeration plant engineering,
hydraulic and pneumatic systems,
process industry or environmental
The pressure transmitter is suitable for
cost sensitive as well as demanding
measuring requirements.
Due to its high accuracy and the
digital adjustability by a FSK operating
unit or by RS485 Modbus RTU, the
device can be suited a wide variety of
The robust design and the high-quality
workmanship turns the device into
a very high quality product, which
even the most adverse environmental
conditions cannot aect, whether
the lowest temperatures when used
outdoors, extreme shock and vibration
stress or aggressive media.
A captive laser marking of the type

throughout the entire lifetime of the
Obviously is the optional marking of a
measurement point designation resp.
TAG, a customer label or of a neutral
type label, of course also per laser
marking, possible.
A LABS-free resp. silicone-free
version, a factory calibration with
calibration certicate and a customer
specic conguration resp. preset is
also optionally available like a material
test certicate EN10204 3.1.
Customer specic special versions
can be realized on request, e.g. other
connector, other process gasket
(EPDM, NBR, FFKM, etc.) or special
designs for the process connection.
