780 Liquid Sampler
The 780 Liquid Sampler is designed to take samples from lakes, rivers, sewage systems, pumping stations, etc. The sampler 780 can be connected directly to MJK Flow Converter 713, for flow proportional sampling.

The 780 Liquid Sampler uses the pressure and vacuum sampling method. When the sampler receives the start signal from either the control panel or an external controller, the sample tube is pressurized to clear it of any residue from the previous sample.

Electrode control 501
The Electrode Control 501 is a simple and price favorable system for the control of level. The system includes a level relay for DIN-rail mounting combined with a range of different level electrodes.
The Electrode Control 501 is used for the control of e.g. a pump or for detecting high or low levels. Used as a level alarm, the soldering bridge determines whether to register a high or low level.

Float switch 7030
Float switch 7030 belongs to a new generation of float switches where the mercury switches used previously have been replaced with up-to-date environment friendly materials.
Float switches are often used environmental engineering systems such as pumping stations and sewage plants, so it is very important that the switches do not contain mercury.

Shuttle^® Ultrasonic level transmitter
Ultrasonic measuring system with measuring ranges from 10 cm to 15 meters.
Learning function, so the level meter recognizes how the wet well is arranged with pumps, piping and other disturbing elements. The measurement will not be affected by false echo. Very narrow ultrasonic pulse signal gives great signal strength and minimum sensitivity to foam and sludge on the surface of the liquid.

• Programble for zero point and span.
• Measuring ranges between 0 – 30 cm and 0 – 300m.
• Housing of PPS plastics.
• 99,9 % pure ceramic diaphragm.
• More flexible measuring ranges.
• Improved accuracy (0,2 %) and stabilit

Pressure Level Transmitters
MJK Pressure Level Transmitters are designed for level measurement by immersing the pressure transmitter in open tanks, wells and containers.
The transmitters are rugged and designed to handle tough applications such as wastewater and sludge.

pHix® Compact

Hix® Compact's integral design includes electrodes, fittings, cables and transmitter built together in one unit, eliminating problems associated with bad cable connections or leaky fittings. Electrodes can be changed without the use of toolsand there is no wiring to install back to the transmitter.

The innovative design allows for simple installation in pipes and open tanks and eliminates additional fittings.

SuSix® Turbidity and suspended solids transmitter

For measuring sludge concentration in waste water plants and turbidity at waterworks.

The MJK SuSix® sensors’ 6 optical windows and its patented measuring system delivers measurements from turbidity in clean drinking water to suspended solids in heavy sludge, all from only one sensor model. The ranges covered in turbidity are 0,001 to 9999 FNU / NTU / FTU and suspended solids in the range from 0,001g/l to 400 g/l.

SuSix® Turbidity and suspended solids transmitter
 

Oxix® Dissolved Oxygen transmitter

Oxix® Dissolved Oxygen measurement Transmitter is developed to measure dissolved oxygen in water and wastewater processes. The optical sensor has no consumable parts like membranes or chemicals, and the optical sensor is almost maintenance free. When the sensor’s built in tubing connection is connected to a valved air or water line, a regular flushing of the optics can be controlled by the converter.

The Oxix® dissolved oxygen transmitter is a unique system that combines advanced electronics with a solid-state optical sensor. No other dissolved oxygen system can compare with the features and benefits of this revolutionary design.

Pump controller 704

The 704 Pump Controller can be used to control up to 4 pumps or valves between adjustable levels. Functions for control, alarm, indication and flow calculation are selectable.

The MJK 704 Pump / Level Controller is delivered with either an ultrasonic sensor or a hydrostatic transmitter. 

The Level Controller is supplied with data communication capabilities so that it can be connected to a SCADA System.

Pump Controller 704
 

ConTroller 712 is a compact unit for control of 2 pumps or valves with optional alternation and also an alarm output.

ConTroller 712 can control 1 or 2 pumps by means of level electrodes and a timer. The pumps are started when the level reaches the start electrode, and is stopped either when the level goes below the stop electrode or after runout of a timer.

Pump controller 701

Pump Controller 701 is a compact unit for level control of 1 pump and 1 alarm or for 2 pumps in alternating service.
Pump Controller 701 is supplied either complete with sensor and cable bracket or as a separate unit. A suitable sensor is MJK Pressure Transmitters type 7060 or 7070

Connect

It is both pump controller and SCADA devices in a single unit. Connect® is the result of intensive development work from one of the industry's leading instrument manufacturing companies. Connect® is designed and manufactured by MJK in Denmark. Our first product for pump station monitoring and control was developed in 1983. Since then MJK has gained experience in pump controls / RTU's and that is now integrated into the Connect®. A clear proof that an MJK product provides a safe and long-lasting choice. Connect® is characterized by its compact design, simple operation and flexible options.

MJK-LINK
MJK-link is a Windows based PC program, applied for controlling and monitoring MJK's Data Transmitter 795, possibly with a connected 4-pump controller type 704. The program enables communication with a Data Transmitter
either as a local data transmission through the serial gate or over the tele-phone with a modem connected to the PC.
MJK-link is built, so that several stations can be monitored from the PC simultaneously. For every station a setup with information on the adjustments of that station is stored. The information is represented on a background, which is a graphical illustration of the relevant station. When MJK-Link
is started, the process picture for the station, requiring the monitoring is derived.
