3.8 Remote seal
Product description
● A remote seal measuring system comprises the following elements:
– Remote seal
– Transmission line, e.g. capillary line
– Pressure transmitter.
● The measuring system based on a hydraulic principle is used to transfer pressure.
● The capillary line and the remote seal diaphragm are the most sensitive components in
the remote seal measuring system. The material thickness of the remote seal diaphragm
is only ∼ 0.1 mm.
● The smallest of leakages in the transmission system leads to the loss of transmission
fluid.
● The loss of transmission fluid results in inaccuracies in the measurement and failure of
the measuring system.
● In order to avoid leaks and measuring errors, please observe the installation and
maintenance instructions in addition to the safety notes.
