编码器专家Postital宣布了新一代的模拟旋转编码器进行位置控制。Compared to the company’s earlier analog encoders, these new models feature improved accuracy, faster dynamic response and new programming options. They also accept a wider range of supply voltages, an advantage for mobile machinery applications.
Postital的模拟编码器设计用于定位使用模拟控制系统的任务。输出是电压（0-5V，0.5-4.5V，0-10V或0.5-9.5V）或电流（0-20 MA或4-20 MA）。磁性测量机制是无磨损且极其耐用的，因此这些设备的准确性，可靠性和使用寿命比传统的电位计提供了更好的精度，可靠性和使用寿命。
POSITAL模拟编码器的一个重要特征s is that they are programmable with measurement characteristics that can be customized to meet specific application requirements, (This feature is also available with POSITAL’s digital encoders with SSI and incremental interfaces.) Programming can be carried out at the factory, in a distributor’s warehouse or at the customer’s job site, thanks to POSITAL’s easy-to-use UBIFAST programming tool.
Programmable characteristics include direction of rotation (CW or CCW), zero set and the encoder output range. Measurement range programming allows the full range of electrical outputs (voltage or current) to be set to match a user-defined range of mechanical motion, resulting in significant improvements to control system accuracy. For single-turn models, the measurement range can be set to 90°, 180°, 270° or 360°. For multi-turn models, the range can be set anywhere between 1 and 65,536 complete rotations. Analog encoders are available with push-buttons on the housing that enable the user to easily specify the upper and lower limits of the mechanical motion, with the electrical output fully spanning this range.
Finding the right analog encoder for a specific application is straightforward. The web sitewww.posital.com提供功能强大的产品查找器工具，使客户能够指定每个应用程序所需的产品功能，然后在最合适的产品中快速零。
