Digital Scalers are used to apply a single multiplier or single divisor (K-factor) to a frequency-based signal to adjust the frequency.

Signals from Variable Reluctance or RF Eddy Current sensors can be directly accepted with the appropriate options. All models accept a digital signal from Hall Effect sensors as well as Signal Amplifiers.

A wide range of integer values can be used for multiplication or division on the 4057 model. This model also has the option to incorporate both FTC & FTV conversion circuits (e.g. 4-20 mA or 0-10V Analog output signals) as an output signal.

The 4057D can multiply with a smaller range of decimal values (from .001 to 100, up to three decimal places). This model can only produce a digital output signal.

All settings can be adjusted and current readings viewed through an integrated LCD screen.

Available in a puck style housing that can be mounted in electrical cabinets or conduit enclosures.

The 4057 is a user programmable pulse multiplier, divider, or K-factor scaler. An optional analog output converter can be included, which requires no external test equipment for setup. Output modes are quickly selected via a backlit LCD screen and push-button dial. Models are available for inputs from magnetic VRS, RF, digital amplified pickups, proximity sensors/switches, and other square wave sources. Removable terminal blocks can be factory configured for back panel or control panel mounting.

The input frequency can be either multiplied or divided by a user selectable integer. The optional analog output can provide either a voltage or current signal with both minimum and maximum set points adjustable.
