The Datum Shaft Power Measurement Kit open the opportunity to collect torque, power and RPM data accurately on site. The Shaft Power Measuring Kit from Datum Electronics provides engineers with the opportunity to measure and monitor shaft power accurately in the field. The kit can be applied using minimal skills in six simple steps and provide accurate data on a portable PC within less than an hour.

Key Features

Key Features

The SPMK is ideal for single day trials, to access power levels and torque characteristics such as start-up or maximum torque levels.

It is designed to be easily fitted with a minimal of on-site operations. The strain gauges used are supplied with the connector to remove the need for soldering and have an encapsulated coating to simplify environmental sealing.

The system provides an output of shaft torque, shaft rpm and shaft power. The instrumentation has an accuracy of 0.1%

The kit is supplied with a simple to use PC utility to display and log the data and optional interface is available to provide 4-20mA or +/-10vdc for logging and control systems.

Shaft Power Measurement Kit


  • Shaft Sizes from 30mm
  • Battery Life 10 hours as standard
  • Single Channel
  • Thrust Option Available
  • Shaft Speed Sensor
  • PC Software

System Advantages

  • Measures Shaft Power, Torque & Speed as a basic function
  • Easy To Install with a step-by-step guide
  • Portable & Lightweight Design
  • Logs, Records & Dispalys ‘Real-Time’ Data
  • User-Friendly Software (included free of charge)
  • Compatible with Data Channel & Shaft Speed

The Datum Electronics Shaft Power Measurement kit is designed to measure the on-shaft torque for trials and torque testing applications on rotating shafts from 30mm in diameter. It can be used as simple testing of power levels or as a key tool within extended trials to assess fuel efficiency or performance improvements.

The system is designed for measuring power and torque on drive shafts, applications including marine ship shafts, prop shafts and vehicle drive shafts.

Measurement & Analysis

The Datum Electronics Torque Trials Kit does more than just measure Torque; it can be used to verify power outputs from engines and motors.

  • Power Transmission
  • Torque Trials
  • Power Transients
  • Peak Torque Levels
  • Power Delivery
  • Can also assist with Shaft Vibration measurement

The main advantage of the shaft power and torque trials kit 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.

Permanent Shaft Power Measurement Systems

We also have a commercial ship shaft power meter system, developed to meet the requirements of marine industry customers, is used on vessel propeller shafts to measure ship performance data any time including shaft horsepower, torque, and RPM and compare historical data on an hourly, daily, monthly or annual basis. The system is modular, has a flexible shaft fit and can be installed with a minimal disruption to the ship system.

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.

      • How can I verify and prove my fishing vessel’s declared engine power to ensure licence condition compliance?
        This can be achieved using Datum Electronics’ Shaft Power Management Kit (SPMK) – a temporary declared engine power measurement system which installs directly onto the fishing vessel’s propulsion shaft – with the test data logged and stored for use as evidence.  The SPMK system is designed to be easily installed by the end user in under 30 minutes, then quickly removed again after running an engine test to full power and logging the results in kW.  The Datum SPMK system generates test results accepted by the MCA, MSEVT and many other EU fishery agencies for the purposes of fishing vessel licencing.
      • How can I verify and prove my engine power for my EU fishing licence?
        This can be done temporarily using a temporary shaft power measurement system which installs direct to the propulsion shaft and running engine tests to full power.  The data can be logged and stored as evidence.  The Datum Electronics Shaft Power Measurement Kit is the kit of choice by many EU fishery agencies and is simple, easy to install to prove your engine power unobtrusively and without the need of a team of technicians as it has been designed to be installed direct by customer.  The SPMK system can be installed in less than 30 minutes and removed from shaft after your tests are done with a log file for you to keep.
      • How can I confirm the power that my engine is delivering on my boat
        The Datum Electronics SPMK system can be quickly and easily installed onto the propellor shaft taking up minimal space in less than 30 minutes to accuractley measure the power which can be completed by end user with our simple kit
