CCMCP500变送器批准标签MCP525加速输入/加速输出变送器具有“峰值”或“真RMS”信号检测版本。 CMCP525与所有电压输出加速度计兼容，并提供与整体测量值成比例的4-20 mA输出。每个单元都为加速度计提供恒定电流电源，检查故障，处理振动信号以确定整体振幅，并输出与用户选择的5、10、15、20或25范围成比例的4-20 mA DC电流输入为100 mv / g的g。已通过CSA和UL Class 1 Div 2 B-D认证。
可选的警报模块提供OK（确定），Alert（警报）和Danger（危险）继电器，可选的时间延迟，跳闸倍增，旁路和0至5 VDC输出用于显示。继电器输出可用于触发机器关闭或其他警报。将变送器与现有的PLC或DCS系统结合使用，可形成高密度，低成本的振动监测系统。
可根据要求提供定制的输入和输出校准。
缓冲输出：
安装在设备正面的BNC连接器可访问缓冲的传感器输出信号。这包括未滤波的振动信号和直流偏置电压。便携式测试设备或分析仪可以连接到该输出，而不会干扰其他系统输出。
故障检测：
机载故障检测电路会连续监视换能器是否正常运行。如果发生故障，则输出电流减小至<2 mA，以向读数系统指示故障。设备前部的绿色LED指示灯熄灭，以提供故障的本地指示。
筛选条件：
对于需要监视特定频带的应用，可以指定可选的高通和低通滤波器。这些过滤器是模块化的，可以在工厂或现场安装。每个模块以大约24 dB /倍频程的速率衰减带外信号。可以指定2 Hz至20 kHz的转折频率。滤波器模块可以级联以形成高阶滤波器或创建带通响应。滤波不会影响缓冲的传感器输出。
监视器版本提供警报继电器和跳闸倍增
CMCP500监视器批准标签警报-CMCP500A系列监视器具有两个独立的设定点，带有LED警报指示器和输出继电器触点（“警告”和“危险”）。设定点可通过电位计调节，范围为满量程的0至110％。每个都有1到10秒的可调延迟。对于电阻性负载，SPST继电器触点的额定值为5 A @ 30 Vdc或250 Vac。
用户可以将继电器触点独立配置为常开（NO）（标准）或常闭（NC）操作。继电器通常断电，可以配置为闩锁或非闩锁（标准）操作。闩锁警报可以在本地重置，也可以通过远程触点闭合来重置。
跳闸倍增-监视器通过触点闭合将设定点倍增3倍（可用2倍）。为了避免在机器启动期间触发警报。

The C
MCP525 Acceleration In/Acceleration Out Transmitter is available in either “Peak” or “True RMS” signal detection versions. The CMCP525 is compatible with all voltage output accelerometers, and provides a 4-20 mA output proportional to the overall measurement. Each unit provides constant current power for the accelerometer, checks for faults, processes the vibration signal to determine overall amplitude, and outputs a 4-20 mA DC current that is proportional to a user selected range of 5, 10, 15, 20 or 25 g’s with a 100 mv/g Input. CSA and UL Class 1, Div 2, B-D Approved.
Buffered Output:
A BNC connector mounted on the front of the unit provides access to the buffered transducer output signal. This includes both the unfiltered vibration signal, and the DC bias voltage. Portable test equipment or analyzers can be connected to this output without disturbing other system outputs.
Fault Detection:
On board fault detection circuitry continuously monitors the transducer for normal operation. If a fault occurs, the output current is reduced to <2 mA to indicate the fault to the readout system. A green LED on the front of the unit is turned off to provide a local indication of the fault.
Filters:
For applications that require monitoring specific frequency bands, optional high-pass and low-pass filters can be specified. These filters are modular and can be installed by the factory or in the field. Each module attenuates out-of-band signals at a rate of approximately 24 dB/octave. Corner frequencies from 2 Hz to 20 kHz may be specified. Filter modules may be cascaded to form higher order filters or to create a band-pass response. Filtering does not effect the buffered transducer output.
Alarms relays and trip multiply are available with the Monitor version
Alarms – The CMCP500A Series Monitors have two independent set points, with LED alarm indicators and output relay contacts (Alert and Danger). Set points are adjustable via potentiometer, from 0 to 110% of full scale. Each has an adjustable delay of 1 to 10 seconds. SPST Relay contacts are rated 5 Amps @ 30 Vdc or 250 Vac for resistive loads.
Relay contacts can be independently configured by the user for either Normally Open (NO) (Standard) or Normally Closed (NC) operation. Relays are normally de-energized and can be configured for latching or non-latching (standard) operation. Latched alarms may be reset locally or by remote contact closure.
