Pressure Transmitter
HDA 3800
for Iron & Steel Works Applications
Description:
This high-precision pressure
transmitter was specially developed
and adapted for the sophisticated
measurement demands of steelworks
technology.
The instrument has a very robust
sensor cell with a thin-lm strain
gauge on a stainless steel membrane.
Its outstanding specications
in respect of temperature effect
(temperature drift for zero point and
range are in each case max.
≤ ± 0.01 % FS / °C) and accuracy
(
≤ ± 0.15 % FS typ.)
make it ideally
suited for use in the environmental
conditions found in steelworks.
The excellent EMC characteristics
guarantee signal stability during the
harshest high-frequency, electro-
magnetic interference.
Special features:
Accuracy ≤ ± 0.15 % FS typ.
Specially designed for use in
steelworks and rolling mills
Highly robust sensor cell
Very small temperature error
Excellent EMC characteristics
Excellent long term stability
