PD70210EVB is a multi-functional signal conditioner, designed for special application fields. It mainly serves for the measurement of transducer input signal, with its lightweight design and simple structure, making it popular among the industrial automation application fields. The device provides a wide selection of measurement parameters, including current, voltage, temperature, pressure, acceleration, radial force, torsion force, and position. The base device provides micro voltage and current amplifiers, allowing to make measurements in the range of ±10V and 0~200mA, respectively.

To ensure the stability and reliability of the signal conditioning measurement, the signal conditioner adopts intelligent algorithms to calculate the measurements. It features an adaptive digital filter (ADF) algorithm to calculate the filtered output, in which a high-performance filter is used to remove interference components, noise, and random variation from the signal. This feature also makes it possible to selectively choose either low-pass or high-pass filter method for the application. Besides, the signal conditioner also has zero adjustment function to support the real-time calibration.

Practical working principle:

PD70210EVB is a linear signal conditioner, wherein the input signal is operated with the reference signal, in which the connection can be supplied for the external transducers or voltage/current signal source. The output signals are also generated from the reference signal. The reference signal could be adjusted according to the input signal, in order to keep the reference signal as close as possible to the input signal. This allows the device to measure the input signal without any significant offset or drift due to the reference voltage.

In simple terms, the device can measure the different parameters from the input signal and generate the output signals accordingly. For instance, when the input signal is current, the reference signals are used to measure the current. Thus, the reference signal is in capacity with the current, while the output signals are generated, which are proportional to the current inputs. In the above instance, the output signals generated are in the form of voltage, so that the current can be converted to the voltage signals.

In conclusion, the PD70210EVB signal conditioner provides a broad range of applications and measurements. It is widely used in industrial automation to measure transducer input signals in the range of ±10V and 0~200mA. It also features an adaptive digital filter (ADF) algorithm to remove noise and random variation from the input. Besides, it has a convenient zero adjustment function to make real-time calibration easier. Thus, PD70210EVB is an ideal solution for a variety of applications.
