摘要： Known linear position sensors suffer from inaccuracies owing to severe environmental conditions, such as temperature and humidity. Physical damage to sensors exposed to rugged work conditions is a limiting factor in the expected life of sensors used, for example, in the heavy equipment industry. A pair of loop antennas mounted internal to an extensible coaxial cavity respectively transmit and receive electromagnetic signals in the radio frequency range exciting a transverse electromagnetic field in the cavity when the frequency of the signal corresponds to the resonant frequency of the cavity. The resonant frequency of the cavity is primarily dependent upon the longitudinal length of the cavity. Therefore, a voltage controlled oscillator acts under the control of a sawtooth voltage waveform of a function generator to controllably deliver a variable frequency signal to the first loop antenna. An RF detector monitors the second loop antenna for an indication that the resonant frequency has been reached. At resonance a microprocessor samples the output of the VCO and correlates the resonant frequency to the length of the coaxial cavity. The sensor is particularly suited for use in the heavy equipment industry for detecting the extended length of hydraulic cylinders as it is highly insensitive to environmental conditions and protected from the work environment.
摘要翻译： 已知的线性位置传感器由于恶劣的环境条件（如温度和湿度）而受到不准确的影响。 暴露于恶劣工作条件下的传感器的物理损坏是使用传感器的预期寿命的一个限制因素，例如重型设备行业。 安装在可扩展同轴腔内部的一对环形天线分别在射频频率范围内发射和接收激励腔内的横向电磁场的电磁信号，当信号的频率对应于空腔的谐振频率时。 空腔的谐振频率主要取决于空腔的纵向长度。 因此，压控振荡器在函数发生器的锯齿波电压波形的控制下起作用，以可控地将可变频率信号传送到第一环形天线。 RF检测器监测第二环形天线以获得已经达到谐振频率的指示。 在谐振时，微处理器对VCO的输出进行采样，并将谐振频率与同轴腔的长度相关联。 传感器特别适用于重型设备行业，用于检测液压缸的延长长度，因为它对环境条件非常不敏感，并且受到工作环境的保护。

摘要： A gear speed measuring system which is capable of measuring speeds down to zero, which is capable of use in a rugged environment, and which is relatively insensitive to gear-sensor spacing. The system comprises an electromagnetic sensor (20) connected into the tank circuit of an oscillator (58) to produce an FM signal in which the frequency shifts occur in synchronism with the rotation of a gear (12) or the like. A detector (66) having a reference frequency input (68) converts the FM signal to a digital signal. A microprocessor (48) adjusts the reference frequency (68) as necessary to keep it between the high and low limits of the sensor output. The speed measuring system is applied to the control of the drive unit for a heavy off road vehicle (10) such as a tractor or earth mover.
