The BB-25 and BB-100 are low cost, PCB mountable current sensors. Having a low-profile, they are suitable for may applications. These sensors accurately measure dc and ac currents and provide electrical isolation between the output of the sensor and the current carrying conductor. | Measuring Circuit | Units | BB-25 | BB-100 | | Full scale (FS) dc or ac | +A | 25 | 100 | | Frequency range | Hz | 60k | 60k | | Output | | | | | Full scale output | V | 1.0 | 5.0 | | Sensitivity | mV/A | 40 | 50 | | Linearity (at +25°C) | % F.S. | 1.0 | 1.0 | | Maximum zero offset (at +25°C) | +mV | 20 | 20 | | Influence on Accuracy | | | | | Maximum offset drift with temperature | +mV/oC | 1.3 | 1.8 | | Maximum sensitivity drift with temperature | +%/oC | 0.065 | 0.065 | | Withstand Capabilities | | | | | Dielectric test | kV | 1.0 | 1.0 | | Minimum load resistance | k ohms | 2.0 | 2.0 |
