The ASXP Current Sensing Switch from NK Technologies is designed to solve maintenance requirements for single- and three-phase motors. Courtesy: NK TechnologiesNK Technologies' ASXP Current Sensing Switch is now available with a user-adjustable setpoint from 1 A - 80 A. ASXP Series Current Operated Switches are powered versions of the company‚Äôs switches with integral time delay. For use with 24 V ac/dc or 120 V ac supplies, these switches deliver OEM-caliber accuracy, precision tolerances, low hysteresis and an operation range between 40 Hz and 100 Hz, functionality, said to be ideal for monitoring single- and three-phase motors. They come standard with a robust solid-core enclosure and LED indicators for trip point contact status.

In motor protection applications these sensors provide electronic proof-of-operation and detect current draw changes in the motor caused by pumps running dry or impending bearing failure. The ASXP is less expensive to install and serves as a non-intrusive alternative to differential pressure flow sensors or thermal switches. They also deliver quicker response times than Class 10 overload relays. Users will also benefit from repeatable performance, constant hysteresis and linear response.
