Examples of applications:
- Controlling of an inverter – frequency adjusting
CP-02 is perfect as a controller of frequency and other parameters of inverters. It’s better than a plain potentiometer, especially when there is a significant distance between an inverter and control panel. An additional advantage of CP-02 is that two cables conductors are sufficient and in most cases, cables don’t require shielding.
- Presetting parameters
In an application with simple driver unit based on PLC, regulators, relays it’s often necessary to change process parameters. Using HMI panels is often too expensive and uncomfortable.
CP-02 is the solution to this problems. Connecting it with an analogue input of PLC allows changing it control’s parameters.
Advantages of this application:
– easy setting
– high environmental conditions resistance
– low costs
- Diagnostics and service
The CP-02 current potentiometer is perfect when it comes to diagnosing devices and driver units which involve sensors and have 4-20 mA current outputs.
There is often need to check driver unit or regulator in it’s functioning conditions. It is possible to switch sensor or converter with CP-02 and simulate its behaviour. It helps to find a defect quickly. This application also allows checking of drivers’, regulators’ and relays’ outputs. CP-02 helps to check whether the output is working and whether reaction for changing of the signal is the one that was expected.
- Launching and testing of driver units
CP-02 does a great job when used to launch and test driver units and regulators. It allows quick testing of units outside target machine.
With CP-02 conditions and object’s behaviour can be simulated. It also enables checking of driver unit. All those functions allow quick finding of mistakes and as a result saving time.
- CP-02 as position sensor
The fact that adjusting of current is performed by changing angle of rotation of potentiometer’s axis, allows using CP-02 instead of expensive absolute position sensors. It can control a position of proportional valves, butterfly valves, gates, windows, arms etc. CP-02 allows easy translation from rotary movement to linear movement and by that, controlling parts which move linearly.
When used with float it can be used to measuring of fluid levels. When mounted in pendulum axis it can measure acceleration.
Those are only examples of possible applications of the CP-02 current potentiometer.
