电感式接近传感器是大部分应用的首选产品，其范围涉及机械仪器和自动化设备领域的需要高精度、非接触式地检测金属目标物。作为一个该类产品的市场领导者，倍加福为客户提供创新的高质量的电感式接近传感器以满足世界范围内的自动化和过程控制市场的需求。我们在该领域有多年丰富经验，工作灵活，处处以客户为尊，根据不同客户的需求提供独特的解决方案。
标准电感式传感器产品特性：光滑或螺纹式不锈钢圆柱形外壳；反极性保护和短路保护；LED状态指示M8, M12接插件连接或端子接线方式；PVC，PUR或硅电缆出线方式；2线，3线，4线直流，交流，NAMUR输出方式以及AS-I总线方式输出。
电感式传感器是利用电磁感应把被测的物理量如位移，压力，流量，振动等转换成线圈的自感系数和互感系数的变化，再由电路转换为电压或电流的变化量输出，实现非电量到电量的转换。
在有些应用场合，对传感器的坚固耐用程度有着很高的要求，那么此类螺纹式坚固型不锈钢感应面传感器正是满足这种应用的最佳选择。类似于机械工具制造或金属加工等应用场合，常常会使传感器受到碰撞、磨损和被腐蚀性溶剂或其他流体侵蚀，那么在此环境下，不锈钢感应面传感器就能发挥出它的巨大优势：大大减少停工时间，延长使用寿命，有效提高生产效率。我们的金属感应面产品系列（NMB…）有两种：FE用于检测铁质金属，NFE用于检测非铁金属。
电感式传感器具有结构简单、动态响应快、易实现非接触测量等突出的优点，特别适合用于酸类，碱类，氯化物，有机溶剂，液态CO2，氨水，PVC粉料，灰料，油水界面等液位测量，目前在冶金、石油、化工、煤炭、水泥、粮食等行业中应用广泛。
