Expert 700D

Expert 700D is created especially for level measurement in water borings. The Digital version of Expert 700 is especially recommendable working with Chatter Datalogger.

The diameter is just 16mm which ensures that Expert 700D fits in most boreholes – the measured value is delivered as ModBus RS485.

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

Get stable measurement 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 made sensor provides 4-20 mA loop powered output and  the digital version 700D provides a 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.
