Expert™ Hydrostatic Level transmitter 3400
The MJK Expert™ 3400 hydrostatic level transmitter is accurate and has long term stability. It is very robust and designed for applications in rough environments with aggressive chemicals and fluids.
The Expert™ 3400 with ceramic capacitive measuring system and built-in breather tube for direct air pressure compensation is designed for use in waterworks, sewage treatment plants and industrial applications.
Expert™ 3400 is designed without sharp edges preventing particles from sticking to the house or membrane. The incredibly robust level transmitter is molded in a body of PPS which protects against acids, bases and ferric-chloride.
The analog 4-20 mA output signal can be lead for up to 300meters in the PUR insulated cable, for instance for your RTU.
Using a laptop and free software, you can easily adjust the measuring area to suit your installation perfectly.
Expert™ 3400 is ATEX and UL approved for installation in explosion hazardous areas.
