Tips: 6 attentions for using AC current sensor
- When selecting an AC current sensor, it is important to note whether the perforating dimensions ensures that the wire can pass through the hole of sensor. For example, the hole diameter of 100A ac current sensor can be 20mm, 40mm or 60mm. According to the size of the wire to choose the minimum hole diameter is the most appropriate.
- When choosing a current sensor, pay attention to whether the application environment in the field has high temperature, low temperature, high humidity, strong earthquake and other special environment.
- When choosing a current sensor, pay attention to whether the spatial structure is satisfied.
- When wiring pay attention to the bare conductive part of the terminal, to prevent ESD impact as far as possible, it need professional construction experienced engineer to carry out the wiring operation of the product. The power supply, input, output of each connecting wire must be properly connected, not misplaced or reverse, otherwise it may cause damage to the product.
- Product installation and environment should be free of conductive dust and corrosion.
- Severe vibrations or high temperatures may also cause damage to the product, and attention must be paid to the use of the occasion.
Hall effect AC current sensors are non-invasive current sensors, with 1.0%FS accuracy, 1ms fast response time, 0-50A ~ 0-1500A measuring range, 4-20mA output signal, 12V/24V power supply, fixed installation, excellent linearity and strong anti-interference capacity. Open loop AC current sensors can be connected to AD, DSP and PLC directly. AC current sensors are now widely used for AC current measurement.
