Keeping an Eye on Fuel Costs

As fuel prices will seemingly continue to rise, owner/operators will increasingly turn to systems such as the Digital Torque Meter to help with energy conservation. The system measures horsepower, rpm and torque on rotating shafts by using fiber optic sensors, making the system accurate and reliable.

The system is designed to be flexible, and allows for installation on shafts as small as two in. and as large as 24 in. in diameter. In upgrading the system over the years, Instruments, Computers & Controls has kept evolving customer needs as its guiding force. The standard Digital Torque Meter System typically has a NEMA 4 enclosure up to 30 ft. f r om the shaft, displaying rpm, shaft horsepower and torque. Inputs and outputs can be configured to interface to other onboard instrumentation. A portable system is also available, and can be used from ship to ship. The fiber optic technology allows nearly all electronics, except for the sensor LEDs, to be housed within the NEMA 4 enclosure.

A temporary power cord is connected to the box for quick installation until permanent power can be had. The sensors typically mount across a bearing housing or mounting brackets. Once the system has been installed and initially calibrated, there is no need for recalibration as the system does not drift. The customer is able to recheck calibration at any time.

Installation of the Digital Torque Meter System is performed by the customer, which helps make the unit competitively priced. While a precise, step-by-step manual allows customers to install the system without any training, the company maintains its New Hampshire facility with a simulated shaft that allows customers hands-on training if required.
