Expert 700

MJK EXPERT™ 700 IS DESIGNED SPECIALLY FOR LEVEL MEASUREMENT IN WATER DRILLS. THANKS TO AIR PRESSURE AND TEMPERATURE COMPENSATION, THE NARROW TRANSMITTER PROVIDES SAFE AND ACCURATE MEASUREMENTS OF LEVELS IN PROCESS WATER, DRINKING WATER AND AT GROUNDWATER DRILLING.

MJK Expert™ 700 is a precise 2-wire transmitter with a piezoresistive measuring system, direct air pressure and temperature compensation and built-in overcurrent protection.

With a diameter of just 16 mm, the MJK Expert™ 700 fits into many borings. Here the measurement is sent via 4-20 mA or RS485. Expert™ 700 is produced in stainless steel. This protects the sensor, which is so stable that it will only deviate with approx. 0.5% FS per year.

Measurements in drinking water wells require reliable assessments of water levels. Therefore, Expert™ 700 has an adjustable measuring range from 0-100 meters - even with very accurate temperature measurements from -20 up to 80^◦C. This gives you reliable measurements directly in your SCADA system for years.

For many years, MJK has supplied hydrostatic level transmitters for measurements in tanks, pump wells, open channels and treatment plants. Our stable product range helps you make reliable and accurate measurements - every time.

Measurements in drinking water wells require reliable assessments of water levels. With our Expert™ 700D level transmitter, you never have to worry about inaccurate measurements or devices being damaged by sludge from water wells.

Expert™ 700D has been developed especially for efficient, reliable and stable level measurement in water wells. The hydrostatic level transmitter is based on piezoresistive measurement. This makes it very robust, so that it delivers accurate measurements years after year.

The Expert™ 700D is both efficient, accurate and flexible, enabling it to meet the specific requirements for water measurements today. With a sensor developed in stainless steel, you get a stable solution - in fact so stable that it will only slide with approx. 0.5% FS pr. year.

The sensor also delivers loop-supplied 4-20 mA output, and the digital version Expert™ 700D provides RS485 ModBus signal. This offers you the opportunity to integrate your measurements with most standard applications.

At the same time, the cables are very solid and flexible, making it easy for you to install. Expert™ 700D is therefore a safe and secure choice when you need to measure groundwater levels in your water wells.
