3500/77M-03-00  Recip气缸压力监测器    

3500/77M Recip气缸压力监测器是一个4通道监测器，接受来自内华达州本特利批准的压力传感器的输入，调节信号以对往复式压缩机进行各种压力测量，并将条件信号与用户可编程报警进行比较。
3500/77M监视器的主要目的是提供:
l通过连续比较监控参数与配置报警设定值来驱动报警，从而保护机器。
l为操作和维护人员提供必要的机器信息。
根据配置的不同，每个通道通常对其输入信号进行调节，以提供称为测量变量的各种参数。用户可以为每个活动测量变量配置警报设定值，为任何两个活动测量变量配置危险设定值。
3500/77M的每个通道将提供8个与气缸压力操作相关的测量变量值。与单个腔室相关的五个值如下:
l排气压力
l吸入压力
l最大压力
l最小压力
l压缩比

3500/72M

The 3500/77M Recip Cylinder Pressure Monitor is a 4-channel monitor that accepts input from Bently Nevada approved pressure transducers, conditions the signal to make various pressure measurements for reciprocating compressors, and compares the conditioned signals with user-programmable alarms.
The primary purpose of the 3500/77M monitor is to provide:
l Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms.
l Essential machine information for operations and maintenance personnel.
Depending on configuration, each channel typically conditions its input signal to provide various parameters called measured variables. Users can configure Alert setpoints for each active measured variable and Danger setpoints for any two of the active measured variables.
Each channel of the 3500/77M will provide eight measured variable values that relate to cylinder pressure operation. The five values that relate to a single chamber are as follows:
l Discharge Pressure
l Suction Pressure
l Maximum Pressure
l Minimum Pressure
l Compression Ratio
