Dancer Roll Position Regulator Geared Potentiometer Assemby, Heavy Duty (Double Reduction)
Our Price: $445.00
Our Price: $714.00
This dancer roll position regulator is designed to maintain a process dancer roll at a preset position. During operation the dancer position is indicated by the signal supplied from a potentiometer or other suitable position sensing transducer. The dancer position signal is compared to the command position signal by the regulator. Any error existing between the two signals is amplified and applied to the process drive system in a manner that will tend to cause it's response to reduce the error to zero. The dancer position regulator provides all of the features required to implement a complete high performance, closed loop, control system. This series of enclosed, gear driven potentiometer assemblies are general purpose devices that are designed to be connected to the user's equipment and provide position feedback or command signals to the process control system. They are suitable for dancer position indication, thread tapping head depth control or any other application that requires position information from a rotating drive shaft.
PID Controller with Feedforward Quad Linear Ramp Generator
Our Price: $781.00
Our Price: $552.00
This PID controller module is designed to provide all of the functions required to implement a complete high performance, closed loop, three mode (proportional, integral and derivative (PID)) control system on a single circuit board. In addition to the standard PID functions, the board contains feedforward as well as external bias and signal scaling circuits. All of the function blocks feature compatible signal levels, thus allowing them to be directly interconnected to produce the configuration required for a specific application. The module operates directly from the AC power line or from a unregulated, bipolar, DC power supply. This dither generator module is designed to provide a bipolar triangle or square wave output for use as the dither input to high performance servovalve amplifiers. It should be used in applications where the utmost in system response and accuracy is required. In addition, it may also be used as a general purpose oscillator.
Bipolar Limit Detector Module Geared Potentiometer Assemby, Heavy Duty (Single Reduction)
Our Price: $300.00
Our Price: $590.00
This bipolar limit detector module is designed to provide a relay contact transfer whenever the input signal exceeds one of the trip point settings. Separate relay outputs are supplied for the positive and negative setpoints. Once the contacts transfer, they will remain so until the input signal returns below the trigger threshold. Models are available for use with either voltage or current input signals. This module can be used in bidirectional applications to indicate a direction change or with double solenoid valves as a level controller. The differential input mode allows the module to transfer the relays based upon the absolute difference between two input signals of the same polarity. This series of enclosed, gear driven potentiometer assemblies are general purpose devices that are designed to be connected to the user's equipment and provide position feedback or command signals to the process control system. They are suitable for dancer position indication, thread tapping head depth control or any other application that requires position information from a rotating drive shaft.
