VaRoM is a Valve Rotation Monitoring system designed for reciprocating Diesel, HFO, Gas (Bio, NG) Engines. It is a patented technology that provides continuous, reliable, and safe monitoring of the valve rotation and temperature conditions of engines. VaRoM is an innovative product, provides a vital data for Diesel/HFO Engines which has never been monitored before.
Valve Seizure or Valve Break Failure is one of the catastrophic incidents that frequently happens in Diesel/HFO Engines due to bad combustion deposits and corrosion on valve stem and guides and result in very expensive property damages like cylinder head, piston, connecting rod, liner, and turbocharger. Rehabilitation and repair works will take too much time, effort and costs.
VaRoM will minimize this risk by enabling 7/24 monitoring of valve rotation and temperature. Conventional sensor technology cannot be used inside the engine, and on moving parts, due to harsh working environment. VaRoM is the first product introduces batteryless and wireless sensor solution and can be installed inside the engine. No cables or power source is needed, because VaRoM generates its own power by energy harvesting from vibration of the valves. And transmits the collected data via wireless communication protocols. Operators can monitor and follow each valve’s real time data on SCADA, and in case of any indication of valve seizure, pre-alarm or shutdown alarms will save the engine components on time. VaRoM can be easily adopted and installed on various engine types and models.
VaRoM is an innovative product, provides a vital data for Diesel/HFO Engines which has never been monitored before. VaRoM is developed for Diesel Engine Manufacturers, Power Plant Owners, Marine Shipowners, Power Ships, Operation and Maintenance Service providers.
VaRoM is a solution for reducing the risk of valve seizure in diesel/HFO engines by providing 24/7 monitoring of valve rotation and temperature with a batteryless, wireless sensor installed inside the engine. The sensor uses energy harvesting from valve vibration and transmits data via wireless communication, monitored through SCADASCADA is a system for high-level supervision and control of machines and processes using computers, networked data communications, graphical interfaces, and connected sensors and devices such as programmable logic controllers.Read More. In case of valve seizure, VaRoM provides pre-alarm or shutdown warnings to protect engine components. VaRoM is easy to install and can be used with various engine types and models.
VaRoM is the first solution to be installed on the inlet and exhaust valves of engines. Unlike other monitoring systems, VaRoM is battery-less, wireless, and easy to install with a plug-and-play design. It also uses vibration energy harvesting and power management circuit, making it an energy-efficient solution.
VaRoM uses temperature, accelerometer, and gyroscope sensors and has a sampling refresh rate of 40 seconds. The system consumes less than 500 μW of power and has a data transmission range of +8 dBm. The operating temperature range is between -40 to +105 Celsius.
The installation of VaRoM is easy and requires only 3 M6 bolts. No power or data transfer via wires is necessary as data is collected from battery-less Bluetooth sensors and transmitted to the server via a sensor hub module. VaRoM is customizable to fit various industrial interface options.
Data collected from the sensors is transmitted to a server via Bluetooth Low Energy (BLE)Bluetooth Low Energy is a wireless technology marketed by the Bluetooth SIG for applications in healthcare, fitness, beacons, security, and home entertainment industries.Read More or Wi-Fi
