EXPERT™ 700D LEVEL TRANSMITTER

EXPERT™ 700D IS A HYDROSTATIC LEVEL TRANSMITTER SPECIFICALLY DEVELOPED FOR LEVEL MEASUREMENTS IN WATER DRILLINGS. THIS MEANS THAT YOU GET A TRANSMITTER PROVIDING ACCURATE AND ERROR-FREE MEASUREMENTS AND DEMANDING MINIMUM MAINTENANCE.

Since the method can be adapted to most types of measurement tasks, hydrostatic level measurement is a reliable and flexible way of measuring water levels. Expert™ 700D is a digital version of Expert™ 700, and it is particularly advantageous to use it with the MJK Chatter™ Datalogger.

In order to ensure reliable assessments of water levels in your water wells, Expert™ 700D has an adjustable measuring range from 0-100 meters and - in addition, very accurate temperature measurements from -20 to 80° C. This guarantees you reliable measurements directly into your SCADA system year after year.

With a diameter of just 166 mm, the Expert™ 700D fits into many boreholes – and it is often used in water boreholes with very narrow pipes. Although the measuring range of the transmitter is predefined, it can easily be changed if you wish. This offers you a very flexible solution that can be adapted to your specific needs.

In order to always provide correct water treatment, the Expert™ 700D is easy to install and has built-in overcurrent protection as well as direct air pressure and temperature compensation. Furthermore, Expert™ 700D is produced in stainless steel, which protects the sensor and keeps it stable.

The Expert™ 700D offers much robustness, reliability and a simple installation. This is your guarantee that you get a level transmitter meeting the strict requirements for safe assessments of water levels and quality. We work hard to deliver world-class transmitters. If you want to hear more about the Expert™ 700D or our other measuring instruments, you are always very welcome to contact us for advice and guidance from our competent employees.

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.
