Motor Monitoring Applications – NK Technologies

Electric motors are found extensively in both the manufacturing and processing industries. Both AC and DC powered motors are used to drive pumps, fans, conveyors and a broad range of specialized equipment. There are many types of motors designed for many different applications, however all require electrical current in order to generate the magnetic fields that are necessary to create rotation. By measuring this current useful information can be made available regarding the status of the motor and the equipment that is connected to it. This may be as basic as independently verifying the run status of the motor or in conjunction with a PLC, for example, to protect a pump against dry run. Thus current may be used to both monitor and protect motors and motor-driven equipment.

Encoder Mounting Configuations

Illustrating the various method of correct Incremental Magnetic and Absolute Encoder Mounting Configurations.

In all cases refer to relevant installation instruction and correct fit-up tolerances. The use of anti-backlash coupling for shaft to shaft coupling is advised.

Encoders are applied to measure speed and position in a wide variety of applications and are therefor available with numerous mounting styles. The mounting style should be selected carefully to best fit the application at hand.

VersaCount by Veeder-Root

The NEW Veeder Root VersaCount 1/16 DIN size multifunction counter is the most versatile counter on the market today. Whatever your application, timing, counting, rate measuring, position indicating, volume measurement, speed monitoring, length cutting or batch, shift, pulse or piece counting, the VersaCount is the only device you need when versatility counts.

Versatility doesn’t stop with functionality. The highest count frequency in the industry enables the VersaCount to perform in applications not previously possible with an electronic counter.  What would speed be without accuracy? That’s why the VersaCount features an unprecedented prescaler accuracy to one ten thousandth. Further, automation and precision control are achieved using three presets with relay hold times programmable up to ten minutes.

Veeder Root is the first in the industry to offer a programming assistant where applications can easily be created, archived and printed using the proprietary Programming Assistant software. VersaCount XP models allow the user to easily upload programs via USB key or Ethernet connection.

Fast input frequency up to 60 kHz allows for high speed counting and measuring applications
Up to 3 Presets for precision control (1 as absolute or trail preset, range or limit value; 2 with relay output)
Relay hold times programmable up to 10 minutes for a variety of application requirements
Prescaler adjustable from 0.0001 to 99.9999 for industry leading precision.

Conveyor Jam Protection – NK Technologies

When conveyors jam and the drive motor continues to run, expensive mechanical damage to the drive components often occurs. By installing an NK Technologies’ Current Operated Switch an overload condition, detected by higher than normal running amps, can be used to switch off power to the motor before mechanical damage results. The switch setting can be adjusted so it is not affected by normal changes in conveyor load. Current operated switches are the modern day equivalent of less reliable electromechanical jam relays that have been in use for many decades.

In situations where there may be large variations in load an NK Technologies Current Transducer can be used to monitor conveyor motor amp draw and output this data to the conveyor control systems, commonly a PLC. The PLC may be programmed to accomodate different setpoints for different mechanical loads so that jam protection is provided from light to heavy loads. In situations where the conveyor is not able to accept analog signals NK Technologies has developed a patented transducer with a frequency output suitable for the Digital Inputs of most PLC’s.

Swiss Flow


The SF800/6 is the high-pressure version of the SF800 with extra metal enclosure. With an operating pressure of 250 bar and burst pressure of 750 bar, it is perfect for more demanding and high stress environments while retaining the versatility and other qualities of the SF800.

The inside of the sensor is similar to the SF800, and is made of high-quality plastics and composites with great chemical and thermal resilience and no susceptibility to limescale.

An integrated PCB emits the infrared signal, which is interrupted by the three blades of the rotor. SMD components transform the interrupted signal into a pulse. Because of the construction and geometry of the rotor housing, the Swissflow flow sensors can withstand high pressure.
