| | | Accuracy Accuracy, linearity, resolution, stability and bandwidth are far better than with conventional nanometrology sensors like LVDT or strain gauge sensors. Non-contact operation means no parasitic forces influencing the application and results in measurement free of friction and hysteresis. Guard-Ring Design for Improved Linearity Sensor design has a strong influence on linearity. The superior PI design uses a guard-ring industrial electrode that eliminates sensor electrode boundary effects. This ensures a homogenous field in the measurement zone and results in higher measuring linearity. Single- and Multi-Channel Electronics | | high bandwidth, linearity and ultra-low noise and are perfectly matched to the various PI sensor probes. PI offers signal conditioner electronics and controllers for one to three channels. The E-509 multichannel modules plug into the modular E-500 / E-501 controller chassis. Bandwidth and measurement range can be factory-set to meet the specific needs of each application. The E-852 one-channel signal conditioner electronics for PISeca™ single-plate sensors are designed as stand-alone systems with user-selectable bandwidth and range setting and can be synchronized to operate in multi-channel applications. | | Easy Handling and Integration PISeca™ single-electrode sensors are particularly easy to install in a measurement system. On the single-channel electronics, an LED-bar indicates the optimum probe-totarget gap for the different measurement range settings. The multi-channel electronics come optionally with displays and/or a PC interface on a module in the same housing. | | |
