SPM振动传感器TRV系列介绍
传感器 TRV-20 和 TRV-21 是带有内置前置放大器的压缩型压电加速度计，专为工业机械的振动监测而设计。 该传感器与 CMS 系统（测量单元 VCM）和手持式仪器 Leonova 一起永久安装。 传感器和测量单元之间的电缆长度不超过50 m（165 英尺）。
传感器安装在机器上光滑平坦的表面上。 TRV-20 的螺纹尺寸为 M8，TRV-21 的螺纹尺寸为 UNF 1/4"-28。传感器附带三个垫圈，用于调整连接器角度。每个垫圈将传感器旋转 90°。同轴电缆（SPM 90005-L 或 带有 TNC 连接器的 90267-L) 必须用靠近传感器的夹子固定。
在潮湿环境中，请使用密封 TNC 电缆插头 SPM 13008 以防止电缆腐蚀。 对于电气绝缘，请使用绝缘安装脚 TRX-18/19。
The transducers TRV-20 and TRV-21 are piezo-electric accelerometers of compression type with built-in preamplifier, designed for vibration monitoring of industrial machinery. The transducers are used in permanent installations with the CMS System (measuring unit VCM) and with the hand-held instrument Leonova. The cable length between the transducer and the measuring unit is max. 50 m (165 ft).
The transducer is mounted against a smooth, flat surface on the machine. TRV-20 has thread size M8 and TRV-21 has UNF 1/4"-28. The transducers are delivered with three washers for adjusting the connector angle. Each washer turns the transducer 90°. The coaxial cable (SPM 90005-L or 90267-L) with TNC connector must be secured with a clamp close to the transducer.
In moist environments, use sealing TNC cable plugs SPM 13008 to prevent cable corrosion. For electric insulation, use insulated installation foot TRX-18/19.
