Manual
General
Safety instructions 1: Read this manual carefully.
Product identification and pressure ranges
Model 1100 Nominal pressure
range 0 - 10 ft, 0 - 30 ft, 0 - 100 ft. Other ranges available; see data sheet.
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.
2: Be aware of the environment on the
installation site. Wear neseccary protec­tive equipment and follow all current safety regulations.
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:
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.
3: MJK Pressure Transmitters must not be
used in explosion hazarduous areas.
4: MJK Pressure Transmitters must not be
submerged into flammable liquids.
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.
Model 3100 Nominal pressure
range 0 - 1 ft, 0 - 3 ft, 0 - 10 ft. Other ranges available; see data sheet.
