The WEC/WDEC410 Series Single and Dual Input Electrodeless Conductivity Controllers measure conductivity of a solution via an encapsulated, non-contacting sensor to control replenishment pumps and alarms. They may be installed in a variety of very harsh chemical control applications, including oily cleaner baths, chromates, rinse tanks, fume scrubbers and other concentrated chemicals up to a conductivity of 1000 mS/cm. Four conductivity ranges may be selected to configure the controller over a wide range of applications. Choice of measurement units is µS/cm, mS/cm, ppm and % concentration. The non-contacting, toroidal sensor technology is immune to thin coatings and the contamination and calibration problems that direct contacting sensors are prone to. Integrated datalogging is available to validate performance. With a USB memory stick data and event logs that include conductivity measurements, temperature and relay status can be extracted. Then download log files from the USB stick

Measurement and control In this sector, MPT represents the interests and products of WALCHEM Corporation in Holliston, Massachusetts (USA). WALCHEM is a leading manufacturer of sensor technology and controllers for the surface technology and for the water treatment technology, including pH-, redox and conductivity controllers as well as special controllers for the cooling-water and boiler water conditioning. Besides the measuring transducer, these controllers include also a control program, adapted to the respective application. Monitoring, alarming – control and telecontrol systems By default, WALCHEM’s WebMaster has available sensors and data amplifiers for various physical parameters. Using the integrated program the parameters can be linked to each other and to control parameters. Via telephone modem and Ethernet board the user is provided with information such as alarm messages and off-limit conditions worldwide.  Measuring and control technology for dosing liquid media in
