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.

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.

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 It is very important for the overall measuring pressure ranges 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:

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.

	Item number		Pressure range
	Item description		Serial number

The same information plus cable length is printed on a similar label tagged onto the transmitter cable.

For all verstions the pressure range can be determined through the serial number.
