3500/77M Main Features
Continuous monitoring and protection:
3500/77M initiates alarms and protects machinery by continuously comparing monitored parameters with configured alarm setpoints.
It receives input from pressure sensors recognized by Bentley Nevada and measures various pressures in reciprocating motion.
Provide important information:
Provide basic machine information to operators and maintenance personnel to help them better understand the operating status of the equipment.
User programmability:
Users can configure alarm and danger settings for each channel as needed.
Each channel will provide eight proportional values (PPL) related to cylinder pressure operation, including exhaust pressure, suction pressure, maximum pressure, minimum pressure, and compression ratio.
