3500/77M Bently Nevada 176449-07 Recip Cylinder Pressure Monitor

Description:

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
