NK Technologies AG Series, AGL Series, and AGT Series Ground Fault Relays   This electrical occurrence doesn’t get the attention it deserves since it can kill you, burn your building down, or damage expensive instruments. A ground fault occurs whenever there is an unbalance of current flow which normally flows from the hot side of the circuit to the neutral. Many things can cause an unbalance which will result in current flow partially or not at all from hot to neutral. Where, how much, and how long does that improperRead More

NK Technologies Installation Without Interruption for Critical Current Monitoring!   Click here to submit a technical inquiry or quote request for the AT/ATR-LS Current Transducer The need to measure electricity usage has become very important to factories. The proposed EPA regulations will soon become law and make power much more expensive, every year for the foreseeable future. Likewise, the efficient operation of electrical machinery becomes more important since poor efficiency equals more electricity. A major problem for existing installations, especially large units, which currently do not have current measurement realRead More

NK Technologies Guaranteed Jam Protection For Conveyor Systems   Click here to submit a quote or technical inquiry for the ATS Series For a long time electromechanical relays have been used for jam protection to prevent drive motors from continuing to run during a conveyor jam. Unfortunately, these relays have questionable reliability. If the drive motors continue to run during jams, system elements including the motors may be damaged. That means expensive and time consuming repair and/or replacement, but even worse, down time for the entire conveyor system. Now aRead More

AC Current Monitoring for Pumps   Electric motors consume 60 to 70% of the energy used in the industrial environment. The cost of replacing even a small motor needs to be carefully analyzed. 1. Labor to access and remove failed or damaged motor. 2. Repair or replacement cost. 3. Labor to reinstall motor. Often Murphy strikes and the motor is virtually inaccessible, and/or is connected to the pump shaft or gearing. Because it affects thruput, that loss is added to the repair/replacement cost. Standard motor starters with thermal or bimetallicRead More

New APN-R Power Monitor with Rogoswski Coil Inputs for Improved Accuracy   Request More Information The APN-R Series Power Monitor measures three phases of current and voltage and computes fourteen values necessary to track power usage. The monitor uses flexible current sensors to measure the amperes, and the line voltage connects directly to the transducer, up to 600 VAC. The result is 14 data points in the RS485 Modbus RTU format. There is also a pulse contact which opens and closes as watt hours are accumulated. The APN is factoryRead More

  NK Technologies New ATS AC Current Transducer/Switch with Digital Display that Shows the Setpoint for Greater Accuracy Now Available at CDI The new ATS Series available at CDI combines two sensors into one package. The factory set analog output calibration produces an accurate and stable signal by eliminating field zero and span adjustments. The trip point is adjustable from 2% to 100% of the analog range, and can be verified at any time by viewing the LCD display on the sensor. Any adjustments made by unauthorized personnel will beRead More

Using Current Monitoring for Predicting Maintenance Request a Product Catalog Electric motors typically account for 60% to 70% of the electricity consumed in an industrial environment. The cost of labor and lost downtime to replace or repair even a small motor can be excessive. Protecting a motor from destruction and controlling a process are completely different requirements. For example, using a standard motor starter with thermal or bimetallic overload protection downstream from a circuit breaker will often prove insufficient to protect the motor from sustained overload conditions. These overload devicesRead More

NK-APT
NK Technologies’ new APT Power Transducer measures three phases of current and voltage, and produces an industry standard analog signal proportional to the watts used. The monitor uses current transformers to measure the amperes, and the line voltage connects directly to the transducer, up to 600 VAC. The APT power transducer can be configured to accept five amp secondary current transformers or the safer ProteCTTM low voltage output sensors. Either type of current sensing will produce an accurate output signal to help you identify areas of excessive energy consumption andRead More

Digital Power Monitoring with the NEW APN Power MonitorCDI announces NK Technologies NEW APN Series of power monitors. The new APN series is a big step forward from analog signal reporting to a digital format that provides information on the system voltage, current and power factor along with wattage. The APN measures three phases of current and voltage and computes fourteen values necessary to track power usage. The monitor uses current transformers to measure the amperes. The line voltage connects directly to the transducer, up to 600 VAC. The resultRead More
