MJK Expert™ 1400 Level Transmitter has
about the same specifications as the 7070
model. In addition it has a ceramic, capaci-
tive measuring system with a much higher
accuracy. Furthermore, Expert™ 1400 is
approved for use in explosion hazardous
areas: ATEX Ex ia IIC T6.
Model 1400 is very useful for level measure-
ments in for example ground water bore
holes and in-fill sites, where explosion proof
transmitters are required.
