Description
Datum Ship Performance Monitoring System – Datum Electronics Series 420 Naval Shaft Power Meter System provides an accurate tool for naval ship performance monitoring. It is able to assess and monitor propeller shafts on naval ships by measuring shaft speed, torque and power.
The Datum Naval Shaft Power Meter System was originally designed for use on the Royal Navy Hunt and Sandown Class Vessels. Later variations have been provided for the Royal Australian Navy, Korean Navy and the Indian Navy.
Datum Naval Shaft Power Measurement System
The Datum Electronics Series 420 Naval Shaft Power Meter System accurately measures the on-shaft torque (kNm), the speed of the shaft rotation (rpm) and the power (kW) that is going through the shaft. The data is transmitted from the shaft in a digital format that can be processed and scaled off-shaft. The data transmitted contains the torque level, the shaft speed and diagnostics data such as the on shaft voltage and power.
The System provides actual data on the power delivered that can be compared with the expected design performance, together with ongoing data, that will indicate any changes to this expected performance level. Condition monitoring of a system of this type is important to any modern day vessel. Being able to accurately measure and record the ship’s power and speed data can help towards determining equipment condition and efficiency. It’s a pro-active measure with the specific purpose of improving performance and efficiency through a ship transmission system.
Spesification
Our naval ship monitoring system assesses and monitors propeller shafts on ships, by measuring shaft speed, power and torque. Originally designed for use by the Royal Navy, later variations have been provided for the Indian Navy, Australian Navy and Korean Navy. The ship propeller shaft power meters have been through rigorous UK MOD and USA MIL testing programmes for the harshest of environments, and are therefore verified in a number of marine conditions, including:
- MIL Spec std. 901-D shock
- 167-1A 2005 Vibration
- Safety Case to JSP430
- Shock to Def Stan 08-120
- EMC to Def Stan 59-41
- Selection of Marine Torsion meters Def Stan 02-606
- Magnetic Ranging to 08-123 DS31
Other environmental tests will include Def Stan 08-123 DS28 (shock), D25 (vibration), DS24 (contamination), DS9 (temperature and humidity) and DS21 (salt atmosphere).
Single or Multiple Shaft Power Measurement Systems
The Datum Electronics Series 420 Shaft Power Meter System can either be configured for a single shaft system or for multiple (2,3 and 4) shaft systems to provide highly accurate non-contact torque measurement of shaft torque, speed and power.Naval Shaft Power Meter System Installation
The Naval Shaft Power Meter System has a shaft installation supplied as a rotor sub-assembly and a stator sub-assembly. The installation onto each shaft comprises a dual bridge strain gauge installation. The installation of the rotor is followed by the installation of the stator. The rotor sub assembly is split into two halves and bolted over the strain gauge installation. The rotor houses the rotor electronics module, acts as a carrier for the rotor coil and physical protection for the strain gauges. The shaft rotor and stator are separated by an air gap of up to +/-12mm to allow for fitting tolerances and shaft movement relative to the stator mountings. The Control Unit is supplied as a complete assembly; it requires four physical mounting points for easy installation and connection to the shaft units, ships control systems, logging equipment and remote displays. The optional Remote Display Units are supplied as a complete assembly, with four physical mounting points.Commercial Marine Shaft Power Meter System
We also have a commercial ship shaft power meter system, developed to meet the requirements of marine industry customers by providing continuous power output measurements, as well as aiding fuel economy and equipment maintenance planning. Robust, permanent, modular and simple to install, the commercial marine shaft power meter accurately monitors the efficiency and performance of the ship’s transmission systems, leading to large savings on running costs.
