Noncontact current transducers help designers to convert high level current signals into simple 4-20mA or 0-10V DC process signals.
Monitoring or controlling motors, heaters or other power consuming electrical devices has never been easier.
With Red Lion's new noncontact current transducers designers can convert high level current signals into simple 4-20mA or 0-10V DC process signals.
These new sensors are available in solid core cases for new wiring, and split core cases to simply clamp over existing wiring.
They are perfect for long cable runs and very cost effective.
The model CTD is a DC current transducer combining a Hall effect sensor and a signal conditioner in a single package.
The CTD has jumper selectable input current ranges of 50, 75 and 100A and provides a self-powered 4-20mA output.
It is available in a split case model only.
The model CTL average responding AC current transducers combine a current transformer and a signal conditioner in a single package.
The CTL transducers are designed for use with "linear" or sinusoidal AC waveforms, and are best suited for constant speed loads or on/off loads.
They feature jumper selectable input current ranges up to 200A and have models with 0-10V DC or 4-20mA outputs.
Models are available in both solid and split core cases.
The model CTR true RMS AC current transducers combine a current transformer and a signal conditioner in a single package.
The CTR transducers provide a "true RMS" output on distorted waveforms found on VFD or SCR outputs, and on linear loads in "noisy" power environments.
Select the CTR series for variable speed or SCR controlled loads.
They feature jumper selectable input current ranges up to 200A and are available in a split core case with a 4-20mA output.
The model CTS AC current operated switches combine a current transformer, signal conditioner and limit alarm in a single package and can be used for status monitoring or proof of operation applications.
They offer an extended setpoint range of 1-150A, universal solid-state outputs capable of switching AC or DC, and are available in both solid and split core cases.
