Introducing a precision pulsed current measurement system with ease of use, state-of-the-art accuracy and portability.  The Resistance Welding Current Measurement Standard/System (RWCMS), Model 1026 is a reliable measurement system.  It is designed to accurately calibrate resistance welding current monitors and related controllers that are in wide use in the welding industry.  The Model 1026 can be used to measure single-phase AC currents.  (Future options will allow accurate measurement of DC welding currents.) 

The RWCMS measurement accuracy is assured because it has been thoroughly tested and calibrated using NIST calibrated high current measurements standards.  Further, HCT Inc. has no affiliation with any welding equipment manufacturer which provides complete independence in the determination of current values.

At the heart of this state-of-the-art measurement system is a precision Rogowski coil air-core current sensor.  RAMTech Engineering and HCT have developed highly accurate, temperature stable and low position sensitivity Rogowski coils for pulsed high-current measurement applications.  This extensive research and development has resulted in a coil that is virtually insensitive to position and external magnetic fields-a failure in many coils which creates unstable and inaccurate readings.  This coils can be used in an y welder secondary loop without effecting the measurement results.
