　　Description: Piezo cable is another form for piezo polymer sensors. Designed as a coax cable, the piezo polymer is the “dielectric” between the center core and the outer braid. When the cable is compressed or stretched, a charge or voltage is generated proportional to the stress. Piezo cable has a number of advantages in certain applications. Due to its coaxial design, the cable is self-shielded, allowing its use in a high EMI environment. The piezo cable can be spliced to passive coax, using standard coax splice techniques. It is extremely rugged, and will stand up to heavy loads as with truck axle counting. Its linear format makes it ideal for monitoring large areas. Two versions of the piezo cable are offered, copolymer and spiral. The copolymer cable is only available in limited quantities. The spiral cable is most commonly used. Continuous lengths of piezo cable are available up to 1000 meters. The jacket on the cable is polyethylene.

　　产品描述:

　　压电电缆是另一种形式的压电薄膜传感器，采用同轴设计，层与层之间采用绝缘材料。当压电电缆受到压力或被拉伸时，会发生压电效应，从而产生与压力或拉力成正比的电荷或电压信号。 压电电缆具有很多优点：由于采用同轴设计，可以达到自屏蔽的效果，使其能应用在高电磁干扰的环境；利用标准的同轴电缆接合技术，压电电缆可以连接到无源的同轴电缆；电缆非常坚固，能承受很重的负载，因此被用于卡车轴数计数；由于其线条的形状，压电电缆是大面积监测的理想选择。 MEAS提供两种规格的压电电缆，共聚物式和缠绕式。缠绕式的压电电缆比较常用，但共聚物的原材料相当昂贵，而且供应有限。压电电缆的长度可达1000米，电缆护套的材料为聚乙烯。

　　特点:

　　自屏蔽，可在高电磁干扰环境中使用
　　坚固耐用
　　适用于大面积监控
