CTX-AC / CTX-ACR Series AC Current Transmitter
Manufacturer: Absolute Process Instruments Aka Api
Mfg Product Code:
The split-core CTX-AC and CTX-ACR series transmitters measure AC current in ranges up to 200 Amps AC and convert it to an isolated, loop-powered, 4-20 mA DC output. These two-wire transmitters consist of a current transformer and a signal conditioner in one compact package.
The CTX-AC is an economical solution where sinusoidal or undistorted wave forms are encountered, such as resistive loads.
The true RMS output CTX-ACR series transmitters can be used for both linear (sinusoidal) or non-linear (distorted) waveform applications. The CTX-ACR incorporates a mathematical algorithm that integrates the AC current waveform over time and provides an output equal to the true RMS value of the waveform. The true RMS output ensures accurate measurements in electrically noisy environments and distorted sine waves from variable frequency drives (VFDs) or SCRs.
The transmitters are designed to withstand harsh industrial environments and can be mounted in virtually any position.
Only two wire connections are necessary for the 4-20 mA DC output. Power is derived from the output loop eliminating the need for additional power wiring.
