- Accepts four supported cylinder-pressure channels
- Calculates suction, discharge, minimum and maximum pressure
- Occupies one full-height front slot in the 3500 rack
Bently Nevada 3500/77M 176449-07 is a Bently Nevada 3500/77M four-channel reciprocating-compressor cylinder pressure monitor identified by spare part 176449-07.
It conditions cylinder-pressure signals, calculates compressor pressure and rod-load variables, and compares configured values with Alert and Danger setpoints in a 3500 rack.
Before installation or replacement, verify the selected internal- or external-termination I/O module, approved pressure transducers, firmware and rack-software revisions, Keyphasor or multi-event reference, channel scaling, machine speed and alarm logic.
Availability, condition, price, and shipping time for 3500/77M 176449-07 are confirmed during quotation.
