Real-World Applications
Engineers at a Gulf of Mexico offshore platform recently implemented this module to monitor their gas compression turbines. They specifically needed its 4-channel configuration to handle multiple vibration sensors on a single machine. The Modbus integration allowed seamless connection to their existing SCADA system without additional gateways.
