Power test systems are made for single-phase and three-phase power quality testing applications. Record and analyze power at any base frequency from milliHertz to 800 Hz, and still add any of the unique DEWETRON capabilities - video, GPS, additional analog sensors, etc. POWER QUALITY is as an add-on to just about any DEWETRON system, so please look at any of our multifunction systems as a platform.

Patented Autophase technology actually corrects common wiring errors. Analog and network models available. Click on the appropriate series to see details below...
...or select data sheets in PDF format from this list.
The AutoPhase Advantage
AutoPhase makes power transducer installation simple.
There are over 40 ways to wire up a 3 phase, 4 wire kW transducer. For example, reversing the orientation of a CT flips the output waveform, tricking ordinary watt transducers into thinking there is a 180 degree phase shift. Or if CT and voltage inputs are mismatched, the transducer thinks there is a 120 degree phase shift. Either way, you have a problem.
AutoPhase identifies the phases and polarity automatically and corrects for the error in software. This eliminates flashing "ERROR" lights, tedious and dangerous reconnecting of inputs. AutoPhase even tells you which CTs are reversed and which phases are mismatched!

Small and practical radiation monitors worn directly on the body are used for personal safety in strong electromagnetic fields. Visual and acoustic warning signals alert the user when threshold values are exceeded, for example during service work on transmitting equipment for radio relay, satellite and broadcast communications as well as radar and telecommunication facilities.
RadMan has been designed for daily use, not just as a warning and monitoring device, but also for taking quick measurements of EMF levels present in the immediate environment and detecting leaks in antenna cables.
The sensors are integrated in an orthogonal pattern, which allows them to measure electrical fields (up to 40 GHz) and magnetic fields (up to 1GHz) separately and independently of direction. This makes it simple and quick to test the EMF situation in the workplace at any time. RadMan is also an excellent tool for finding leaks in cables and power supplies for antenna connections.
Monitors in the RadMan range are also available as an "XT" version with a long-term data memory for monitoring and recording the minimum, maximum and average radiation levels. With the help of analysis software it is also possible to evaluate the results as easy-to-read graphics or tables.

The TAG5000 is the first appliance with cable liaison to be fitted with a transmitter and a receiver with HF radio liaison. It eliminates all hazards related to the use of liaison cables. Its range is up to 20m in the air and 1000m along the network. Obstacles such as walls, doors, etc. do not disrupt the liaison. It can be adapted to all types of insulating rods by means of universal connectors.
