General
Level measuring with a pressure transmitter
is done by immersing a transmitter in the
liquid. The transmitter measures the
hydrostatic pressure and generates a
current signal that is proportional with the
hydrostatic pressure and thus proportional
with the liquid level.
Model 1100
Nominal pressure
range 0 - 10 ft,
0 - 30 ft, 0 - 100 ft.
Other ranges
available; see data
sheet.
Model 2100
Nominal pressure
range 0 - 10 ft,
0 - 30 ft, 0 - 100 ft.
Other ranges
available; see data
sheet.
The MJK Submersible Hydrostatic Level
Transmitters are all designed to generate
a 2-wire (passive) 4 - 20 mA signal with a
10 - 30 V DC supply.
Model 3100
Nominal pressure
range 0 - 1 ft,
0 - 3 ft, 0 - 10 ft.
Other ranges
available; see data
sheet.
Safety instructions 1: Read this manual carefully.
2: Be aware of the environment on the
installation site. Wear neseccary protec-
tive equipment and follow all current
safety regulations.
3: MJK Pressure Transmitters must not be
used in explosion hazarduous areas.
4: MJK Pressure Transmitters must not be
submerged into flammable liquids.
Product identification and
pressure ranges It is very important for the overall measuring
accuracy that the pressure transmitter has
the correct pressure range.
Check that the item(s) delivered corresponds
to the ordered item(s) by means of the
information on the label on the packing:
Shown below is the label for a model 1100
pressure transmitter, range 0-10 ft:
The same information plus cable length is
printed on a similar label tagged onto the
transmitter cable.

On the model 1100 transmitter, all the
standard pressure ranges together with the
corresponding order numbers are printed on
a label on the transmitter housing. The
pressure range can be determined by
comparing the order number impressed in
the steel housing (together with the serial
number) with the numbers on the label.
On model 2100 and 3100 transmitters, the
actual pressure range is ticked off on the
label on the housing.
For all verstions the pressure range can be
determined through the serial number.
