Selection method

Cheemi-tech has a wide range of current, voltage sensors, and transformers with complete specifications and a variety of shapes and connection methods to choose from. Pls refer to the following choosing method,you can get the proper type you need.

1. Firstly, determine the sensor type you need based on the requirements of your system design.

1.1 Power supply---is there a power supply?

1.2 Power supply---dual power supply or single power supply?

1.3 Is it current or voltage that needs to be measured？

1.4 What is the value of the measured current or voltage?

1.5 Is the measured current AC,DC or Pulse Current?

1.6 Are there any requirements for the response time and also Accuracy of the sensor?

2. Secondly, determine the sensor installation method and mechanical installation dimensions, for example: PCB board installation, through-hole installation, or guide rail installation, etc.

3.Finally, you need to consider the on-site use environment such as temperature, humidity, air pressure, energy, light, dust, vibration, noise, electromagnetic field and radiation interference. Please contact our sales staff or technical personnel for details.

Precautions for using hall effect current and voltage sensors

1. When connecting wire, pay attention to the exposed conductive parts of the terminals and try to prevent ESD impacts. Engineers with professional construction experience are required to perform wiring operations on this product. The connecting wires of power supply, input and output must be connected correctly and cannot be misplaced or reversed, otherwise the product may be damaged.

2. The product installation and use environment should be free of conductive dust and corrosiveness

3. Severe vibration or high temperature may also cause product damage, so you must pay attention to the application environment.
