KOBOLD INSTRUMENTATION
Description
The immersion probe comprises a measuring cell, two-wire
transmitter and a special cable with capillary tube. The
housing comprises stainless steel with a pressure-sensitive
diaphragm that is protected with a plastic cap. The level
signal is determined by the pressure difference between the
water column over the probe and atmospheric pressure
which is transferred to the probe through the capillary tube.
This differential pressure is converted to a 4 to 20 mA ana-
logue signal by the piezo-resistive cell and the fitted electro-
nics.
