Expert 7070D

The narrow digital transmitter measures with high presicion and delivers a RS485 ModBus Signal.

Expert 7070D is especially developed by MJK, for low-energy installations and is very easily connected to a Chatter logging device.

One of the great advantages this quality transmitter is that it works for years without the need of manual service, the power consumption is extremely low; it is constructed in stainless steel AISL316. We did that to make it the perfect data logger for monitoring nature resources and lakes, in areas not easily accessed.

Expert 7070D is designed by MJK for the drinking water and surface water industry.
The Expert 7070D provides output as Modbus RS485, and is often connected to the well-known MJK Chatter
The body and the built-in atmospherical air pressure compensation provide stable and trustworthy piezo resistive measurements in boreholes, wells, tanks and basins worldwide.
Not only does Expert 7070D provides exact and stable measurement, but the construction ensures a long lifetime, low service requirements equals low running cost.
The Modbus output signal allows the sensor to be directly connected to e.g. the MJK Chatter, provides extreme high precision on the measured values, and by the low power consumption, providing a long battery life time of the data logger.
Created in an AISL 316L stainless steel body, and equipped with temperature measurement that allows the user to keep track of both level and temperature even in boreholes.

Land based fish tanks need a trustworthy level measurement. The Expert 7070D with piezo resistive sensor provides exact level measurement based on hydrostatic pressure.
Not only does Expert 7070D provides exact and stable measurement, but the construction ensures a long lifetime, low service requirements equals low running cost.
Output is delivered as Modbus signal, this allows the control of pumps to avoid overflow of the tanks. In the micro screens (drum filters) the Expert can provide the necessary signal to start the filter process.

The Expert is in an AISL 316L stainless steel body, and equipped with temperature measurement that allows the user to keep track of both level and temperature even in boreholes.
The extremely rugged constructed body design and the built-in atmospherically air pressure compensation provide stable and trustworthy piezo resistive measurements in waste water wells, water reservoirs and entire water treatment plants worldwide.
