联盟传感器组has announced the ME Series of Linear Position Sensors for embedded use in measuring the ram position of hydraulic and pneumatic cylinders in industrial, mobile, or subsea applications. The ME Series is designed to be drop-in form, fit, and function replacements for embedded magnetostrictive sensors but with much more robust construction and a lower cost of ownership. They can also replace embedded resistance potentiometers, offering high accuracy without wearout. ME Series sensors are based on a contactless inductive sensing technology that uses solid probe construction and requires only a simple conductive tubular target or a small diameter deep hole gun drilled in the cylinder rod for operation rather than needing a permanent magnet ring, counter-bored hole, or any other type of special target.
ME Series sensors can withstand intense shocks and vibration, and operating temperatures up to 85°C用于标准产品和125°C for custom units. ME sensors use a simple coil design rather than “time-of-flight” technology or resistive film. Duplicating the head end of typical embedded sensors, the head of an ME series sensor fits into the same 48 mm diameter cavity as a magnetostrictive sensor or potentiometer fitted into the end housing of a cylinder. For applications where an ME sensor is replacing an existing magnetostrictive sensor, the magnet ring can usually be left in place without significantly affecting the performance of the ME Series sensor.
ME线性位置传感器的全范围为2到36英寸。（50毫米至900 mm）具有模拟直流电压或电流输出，线性误差小于或等于全尺度输出的±0.1％，而-3 dB频率响应为500 Hz。因为它们是无接触式的，所以ME系列传感器不受磨损的影响，并且在传感器的寿命中没有显示输出信号恶化。传感器探针的直径为7毫米（ME-7），用于工业用途，而11毫米（ME-11）用于较重或更大的气缸使用。ME系列标准配备导线，4核电电缆或现场组装的2件M-12连接器。
IP-67密封住房没有修剪器锅来设置零和全尺度。取而代之的是，ASG的感觉校准功能允许用户独立的基础上的操纵器或气缸的模拟输出与执行器或气缸的运动匹配，而不是用户必须在关联的控制系统中扩展传感器的基本输出。
Besides the ME series embeddable cylinder sensor, Alliance Sensor Group also offers a port mounted version called the MR Series, plus a full line of heavy duty LVDTs and electronics for measuring position in power plants, industrial manufacturing, and process control applications.
