英国Hansford HS-530型是一款4通道输出的振动模块，与100mV/g恒定电流型加速度传感器配套使用，用于振动监测与分析。HS-530外形紧凑，导轨式安装在塑料外壳里，工作电压：24VDC, 25mA.

The HS-530 Quad Output Vibration Module is designed to operate with 100mV/g constant current type accelerometers to provide four outputs useful in vibration monitoring and analysis. The unit is housed in a compact DIN-Rail mounting plastic case and operates from 24VDC at 25mA. Terminal connections are shown in Fig.1.overleaf.

供电加速度传感器

HS-530能够给加速度传感器提供3.6mA的恒定电流，这样传感器只需要直接连接振动模块的输入端口。

Accelerometer Power. The HS-530 provides a 3.6mA constant current supply to an accelerometer which connects directly to the module input terminals.

LED状态指示

当传感器与模块连接成功后，模块前面板上会亮起绿色LED灯；当连接错误或者电线短路时，LED不会亮起。这样可以有效避免因输入信号造成的问题，0-10V输出会被设定为0V。

TDX OK LED. A green LED on the front of the unit indicates correct connection of the accelerometer. The LED will not light if input wiring short or open-circuits are present. To prevent problems due to spurious input signals, both 0-10V outputs are set to 0V if the TDX OK LED is not lit.

AC输出

模块通过前面板的BNC连接器，输出一个与加速度型号成比例的带缓冲未过滤AC信号。当数据采集器监测输入信号，进行振动分析，那么该信号必须是AC输入信号，并给传感器供电。

AC Output. A buffered, but un-filtered AC output proportional to the acceleration signal is provided via a BNC connector mounted on the front panel. The 100mV/g signal is not AC coupled and swings about the accelerometer bias voltage level. If a data-collector is used to monitor this signal for vibration analysis, it must set for AC input and have its sensor power function turned off.

速度输出

HS-535也可以输出一个0-10V信号，与RMS速度（mm/s）对应。模块信号调理仪拥有高低通滤波功能，对测量带宽进行限制，限制范围：10Hz - 1kHz，符合旋转电机振动幅度ISO 10816标准。0-10V标准输出范围：0-20 mm/s，加速度版本的输出为 g rms。

Velocity Output. This is a 0-10V output proportional to rms velocity in mm/s. The signal conditioner has high and low pass filters to limit the measurement bandwidth to 10Hz to 1kHz as defined in ISO 10816 which lists recommended vibration limits for rotating machines. The output range is set at the factory at 0-10V = 0-20mm/s as standard. For acceleration versions, this output is 0- 10V proportional to g rms.

加速度g输出

0-10V输出可检测球或滚子轴承的问题，该型号可转换成对应的轴转速。输入电路带宽为500Hz-10kHz，出厂标准输出范围为0-10V-0-10gE。

Enveloped g Output. This 0-10V output is useful for detecting problems in ball or roller bearings where signals from high frequency impacts are masked by the lower frequency vibrations proportional to shaft rotational speed. The enveloper input circuit bandwidth is 500Hz to 10KHz and the output range is set at the factory 0-10V =0-10gE as standard.

AC包络线输出

AC包络线输出是包络检波电路产生的缓冲AC输出，9VDC的震荡基准。100mV/g的输出信号可直接传输至数据采集产品，进行振动分析。

6. AC Envelope Output. This is a buffered AC output from the enveloper circuit which swings about a 9VDC reference level. The 100mV/g signal can be used for vibration analysis via a Data-Collector.
