Q40 500A good linearity universal ac clamp on current ct sensor
The Q40 series clamp on current sensor are high performance current clamp models, and use a custom nickel core to improve accuracy and phase shift on the low end of the measurement range. The Q40 ct clamp sensor is an excellent probe to be used in power and low level current measurement applications detection. The range, transformation ratio, output interface of the sensor can be customized according to customer requirements. Q40 CT clamp sensors, also known as current transformers or current sensors, are devices that measure the current running through a wire by using the magnetic field to detect the current and generate a proportional output. Q40 current CT sensors can be used to measure less than 500A AC current circuit on site.
