In addition, special low noise cables, which are otherwise required for use with piezoelectric sensors, are no longer necessary. The sensor circuit is supplied with constant current. A distinguishing feature of the IEPE principle is that the power supply and the sensor signal are transmitted via one shielded wire.
A common value is 4 mA. The higher the constant current the longer the possible cable length. Cables of several hundred meters length can be used without a loss of signal quality.
Supplying the IEPE sensor with constant current, results in a positive bias voltage, typically between 8 and 12 volts, at the output. The actual measuring signal of the sensor is added to this bias voltage. This ensures maximum amplitudes in positive and negative direction. This can be a drawback in battery powered systems.
For such applications low-power IEPE sensors exist which can be operated at only 0.
Many measuring instruments designed for piezoelectric sensors or measurement microphones have an IEPE constant current source integrated at the input. In measuring instruments with IEPE input the bias voltage is often used for sensor detection. If the signal lies close to the constant current supply voltage, there is no sensor present or the cable path has been interrupted.
A signal close to the saturation voltage, indicates a short-circuit in the sensor or cable.
In between these two limits a functional sensor has been detected. The bias voltage is cut off by a coupling capacitor at the instrument input and only the AC signal is processed further.
Ideal for use in spaces where head room is limited and or a high Sensors available in our range are of the accelerometer type. This means that the measured signal is proportional to the acceleration.
