SAFETY

GENERAL SAFETY

The following section provides Warnings, Cautions and Notes covering general

safety aspects for the Oryx DTS. Please read all of the safety and operational

warnings before connecting and operating this product.

WARNING! THIS IS A W

ARNING SYMBOL. THIS

SYMBOL IS

USED THROUGHOUT THE USER GUIDE WHENEVER THERE IS

A RISK OF PERSONAL INJURY. ENSURE THAT THESE

WARNINGS ARE READ AND UNDERSTOOD AT ALL TIMES.

CAUTION! This is a Caution symbol. This symbol is used

throughout the user guide whenever there is a risk of

damaging the Oryx DTS system. Ensure that these warnings

are read and understood at all times.

NOTES:

Used throughout the user guide to provide additional information, hints and tips.

WARNING! THE ORYX DT

S IS HEAVY. ENSURE A

DEQUATE

CARE IS TAKEN WHEN LIFTING AND MOVING. THE UNIT

SHOULD BE MOUNTED ON A SUITABLE SURFACE OR RACK

MOUNT CAPABLE OF SUPPORTING THE WEIGHT. THE ORYX

DTS WEIGHS 7KG.

CAUTION! Ensure the ORYX DTS is connected to a suitable

electrical supply. 12 – 24VDC should be used.

WARNING! ENSURE THE

ORYX DTS IS ADEQUATE

EARTHED. FAILURE TO OBSERVE THIS WARNING MAY

PRESENT A RISK OF ELECTRIC SHOCK.

WARNING! THERE ARE N

O USER SERVICEABLE P

ARTS

INSIDE. UNDER NO CIRCUMSTANCES SHOULD THE OUTER

CASING OF THE ORYX DTS BE REMOVED. FAILURE TO

OBSERVE THIS WARNING MAY PRESENT A RISK OF

ELECTRIC SHOCK.

WARNING! DO NOT OPER

ATE THE ORYX DTS IN

EXPLOSIVE OR FLAMMABLE ATMOSPHERE. FAILURE TO

OBSERVE THIS WARNING MAY PRESENT A RISK OF

EXPLOSION.

CAUTION! The ORYX DTS should only be operated by suitably

qualified personnel.

CAUTION! Never operate the ORYX DTS if any damage is

observed. Contact Sensornet Ltd for advice.

LASER SAFETY

The ORYX DTS is a Class 1M laser product.

The ORYX distributed sensing system incorporates a pulsed laser device whose

invisible output radiation is potentially hazardous if viewed directly by eye. The laser

radiation emission from the laser within the ORYX DTS is permanently coupled into

a 50/125 multimode optical fibre whose end is terminated with an APC, angled

polished optical fibre connector.

The Oryx DTS should be interfaced to a test fibre, using patch cord or pigtail

assembly, fitted with an APC connector. The far end of the test fibre should be

terminated to prevent free-space emission of laser radiation from the fibre end. It is

recommended that where possible, fusion splices or APC connectors be utilized

throughout the optical sensing network.

Because of the potential hazard posed by laser radiation being emitted from an

exposed fibre end, the following safety warnings, cautions and notices should be

observed.

INTRODUCTION - SYSTEM OVERVIEW

Figure 1 - The Oryx DTS

The Sensornet ORYX DTS unit is an intelligent remote logging unit for collecting

fully distributed temperature data over installed fibre optic cable. The device will

autonomously record the signals from up to 4 fibres, store this data on-board in

non-volatile memory and transmit the data back to a base station computer (or

download to a local PC / laptop). 32MB of on-board memory is available which is

sufficient to store approximately 600 separate DTS measurements. The raw data is

processed (and temperature calculations are performed) on the base station or

laptop and this is where the data is permanently stored. The base station server

runs Sensornet software which communicates with multiple Oryx units in the field

and allows configuration changes from a central control room (CCR). Users can

connect to the base station to view the temperature data using Sensornet software
