Expert 700

Expert 700 is created especially for level measurements in water borings. Due to the build-in air pressure and temperature compensation, the narrow transmitter provides stable measurements.

The diameter is just 16mm which ensures that Expert 700 fits in most boreholes – the measured value is delivered as 4-20mA or RS485.

Measurement of groundwater borings demands exact evaluation of levels. Expert 700 has an adaptable measuring area, from 0-30 up to 0-100 meters. You will get exact measurements even in temperatures from -20 to +80◦C.

You can get your stable measurements directly in your SCADA system for many years ahead. Expert is produced in stainless steel which protects the sensor that holds an stunning deviation by only app. 0,5 % FS per year.

The Expert 700 is an accurate hydrostatic level transmitter based on piezo resistive measurement.
The very small diameter of only 16 mm makes the Expert 700 especially great for water level monitoring wells with narrow pipes.
The stainless steel AISL 316L sensor provides 4-20 mA loop powered output and the digital version 700D provides an RS485 ModBus signal.
The measuring range is programmable, with measuring ranges from 0-30 to 0-100m, and the programmable zero point makes it a perfect solution for boreholes.
