Introduction
The use of a PALCO® torque measuring system means efficiency improvement, overload protection and prevention of breakdown costs. For example, in the shipping industry its application has led in some cases to fuel savings up to 5%. On board of dredgers it has prevented the cutter from unnecessary damage. The system is based on a strain gauge technology and can be mounted around existing shafts between prime mover and machine.
User benefits
Fuel saving by efficiency improvement on ships
Reduction of break-down costs
Preventing damage and overhaul costs
Competitive pricing and delivery times
World wide service network of certified VAF agents
Robust design, maintenance free
Features
With the Palco® Efficiency Monitor (PEM), VAF Instruments has developed a completely new torque measurement system based on many years of experience and proven technology, but with modern user friendly electronics. The PEM, a touch screen PLC, is because of its menu structure very easy to use and all measured and calculated data can be read directly from the screen, on which they are displayed in both figures and baragraphs. The Palco® system helps owners to improve efficiency of ship management or to monitor engine performance.
The standard system is based on torque and speed measurement, out of which the performed power on the shaft can be calculated. The system can be extended with the following modules:
thrust measurement
trip levels on torque
energy consumption
total power calculation
For these extensions other signals can be fed to the PEM, such as fuel flow, temperature, speedlog, GPS or generator power. Together with the standard torque, speed and power signals the PEM will be able to calculate the desired data.
Applications
The standard Palco® Efficiency Monitor design can be used in a variety of applications as:
Continuous power output measurements for ship propulsion
Continuous power and consumption management
Direct visual control of changes in engine setting, trim and draught
Continuous monitoring of torque, speed, power or thrust
Besides these standard applications VAF Instruments also manufactures special designs and variants:
Testbed shafts and spacers
Tailor-made hardware and software
Rotor and stator units in accordance with IP65
Trip level for monitoring maximum allowable power to cutter heads of dredgers
