Series 430 Marine Trials Kit


Datum Electronics Series 430 Marine Torque Trials Kit has been designed to measure the true mechanical torque, power and speed of your ship shaft. The system provides an accurate tool to assess and monitor propeller shafts on ships by measuring shaft speed, torque and power. This trials kit can be installed on a ships propeller shaft or shafts and uses strain gauge technology providing a highly accurate non-contact method of measuring shaft torque.


The System
The Datum Electronics Torque Trails Kit is simple and easy to install. The System provides a display of the torque on the shaft. The torque signal is derived from strain gauges installed on to the shafts. The signals are transmitted from the shaft rotor to the shaft stator unit providing a display of torque.

The Kit is mounted on to the shaft and remains on the shaft whilst trials take place. The trails Kit can fit all types of shaft with a diameter between 150mm – 1100mm.

Measuring Torque on a shaft can provide an array statistical data providing useful information on shaft performance. The Datum Electronics Torque Trials Kit does more than just measure Torque; it can also be used to verify power outputs from engines and motors. The following data can also be measured and analysed:

  • Power Transmission
  • Torque Trials
  • Vibration and Torsional Acceleration
  • Power Transients
  • Peak Torque Levels
  • Power Delivery
  • Shaft Vibration



Data Analysis
The Datum Electronics Torque Trials Kit accurately measures the on-shaft torque (kNm), 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 Trials Kit, once installed on shaft, transmits digital data (RS232) which can be monitored, analysed and recorded into our monitoring system. Because the data is digital data, it is noise immune and easy to process with a USB or serial interface. This provides a clear clean signal of Torque with a system reliability of 0.1%


Installation
One of the advantages is how easy the instrumentation is to install, set up, test and operate. The trials kit consists of three main component elements making this trials application system as easy and simple and possible.

The Shaft - The first basic element of the system requires a shaft between 150 – 1100mm in diameter which is accessible. The trials application uses strain gauges on the shaft which can determine the shaft torque, speed and power of the shaft. One of the first and most important aspects in the installation of the Series 430 Trials Kit is the on shaft application of the strain gauges. The strain gauges must be applied in the correct manner, the importance of attention to detail and precision adherence to instructions cannot be over stressed.

On-Shaft Electronics - The On-shaft electronics consist of a transmitter module and battery supply. Both modules are held to the shaft with a strapping kit. The data signal is transmitted off shaft to Receiver Module.

Receiver Unit - The Receiver Unit receives the data transmitted from the on-shaft transmitter module. The data is then converted and sent to a PC or laptop which will display and record the on-shaft data which will contain the torque data from the shaft and the speed data from the mounted speed sensor. The software utilises the torque and speed data providing power output from the shaft.


System Advantages
The Datum Series 430 Shaft Power & Torque Trials Kit has a number of advantages over other trials applications. The system is simple and easy to install logging directly to a PC or laptop with the aid of its installation software Disk. Other advantages include:

  • Measures Shaft Power, Shaft Torque & Shaft Speed as a basic function
  • Easy to install with a step-by-step guide
  • Logs, records and displays ‘real time’ data
  • Portable & lightweight design
  • User Friendly software
  • Compatible with 2 data channels and shaft speed
