Getting Started

Introduction

The

Rayleigh Wave Rotary Torque Transducer provides a method of precisely

measuring bi-directional rotary or static torque. It can also be fitted with a speed sensor for

monitoring in dynamic applications, enabling direct measurements of transmitted power.

The RWT series transducers require no external instrumentation and has its own built in test

capability. Its compact size makes it ideal for use in applications where there is little space for

any extra equipment. Analog voltage outputs are standard, with current outputs available as

an option. The RWT420/440 series can also be connected to a PC via USB (optional) or

RS232 so that its configuration can be changed, or by using TorqView to display torque,

speed and power.

Unpacking the transducer

The following standard components are included:

▪

1 x RWT Series Transducer

▪

1 x RWT Electronics Module (Only if RWT430/440 ordered).

▪

1 x User Manual.

▪

1 x Calibration Certificate.

Additional components for RWT420/440 series:

▪

1 x TorqView program installation CD, RWT Configuration Software, Manuals &

Appendices in PDF format, USB driver.

The following items may also be included:

▪

12pin Lumberg (female) and/or 12pin Lumberg (male).

▪

1 x 2.5m Analog Lead - 15 way ‘D’ type connector (female) to 12pin Lumberg

(female).

▪

1 x 2.5m Digital Lead - 15 way ‘D’ type connector (male) to 12pin Lumberg (male).

(RWT420/440 series transducer ONLY).

▪

1 x Digital Adaptor Lead (DC Jack with USB and/or RS232 connections, depending

on options requested) (RWT420/440 series transducer ONLY).

▪

1 x Transducer Display ETD

▪

1 x AC Mains Adaptor Power Supply.

▪

1 x Transducer Signal Breakout Unit.

▪

1 x Analog Dongle.

CAUTION

The RWT series transducers should not be operated at any torque load greater or

speed faster than that specified in the Product data sheet and on the Transducer.

CAUTION

The RWT series transducers should be installed using correct couplings rated for

the maximum torque and speed for the operation.

CAUTION

The RWT series transducers should not be operated in an environment where that

operation could be life threatening or a danger to personnel.

CAUTION

In electrically noisy environments, the RWT series transducers should be earthed

using the earthing post located on the transducer.
