Pyrosales is an Australian-owned company that has developed an international reputation as a specialist manufacturer of standard and precision temperature measurement sensors. It is Australia's longest established and largest manufacturer of thermocouples and resistance temperature sensors with operations in Sydney, Melbourne and Brisbane.

With over 30 years' experience, Pyrosales has a sensor to suit your industry and can design, manufacture and supply a sensor tailored to your application.

Thermocouple temperature sensors

A thermocouple is a very popular form of temperature sensor because of its low cost, versatility and ruggedness. It consists of two different metals joined together, making a continuous circuit. When there is a temperature difference between any two points in the circuit, an electromotive force (voltage) occurs.

There are several types of thermocouples, constructed from different metals and with differing temperature ranges and accuracies.

Pyrosales can both measure temperatures and - using temperature-control instruments - control them.
Pyrosales' high-quality RKC temperature-control instruments come from Japan.
Pyrosales is the authorised distributor for S-Products temperature transmitters.
Infrared radiation thermometers measure temperature without contact.

Resistance thermometers

A resistance thermometer or RTD is a temperature-sensing device that changes resistance at a predetermined rate in response to changes in temperature. It is a circuit element whose resistance increases with increasing temperature in a predictable manner.

Platinum is the most popular material, though copper and nickel are also used in RTDs. They can be wired in two, three or four-wire configurations.


Thermowells are among the simplest yet least-publicised accessories used in industrial temperature measurement applications. There are many variations of two basic kinds; low pressure and high pressure. They are used to provide an isolation between a temperature sensor and the environment, either liquid, gas or slurry. A thermowell allows the temperature sensor to be removed and replaced without compromising either the ambient region or the process.

Temperature-control equipment

Pyrosales can not only measure temperatures but also control them, through its extensive range of quality RKC temperature-control instruments from Japan.

Solid-state relays

Since its introduction, the solid-state relay has gained acceptance in many areas which had previously been the sole domain of the EMR or the contactor, and today its applications are almost limitless. Key applications include heat/cool temperature control, motors, lamps, solenoids, valves and transformers.

Pyrosales has an extensive range of solid-state relays to cater for all of your control requirements.

Temperature transmitters

Pyrosales is the authorised distributor for S-Products temperature transmitters. No matter what signal input you require, the company can provide a converter to suit your requirements. They can be supplied as isolated or non-isolated transmitters in either a 'hockey-puck' style or in a 'Din-rail' mount package.

Handheld temperature testing and monitoring instruments

Pyrosales carries a comprehensive range of handheld instruments to provide for all of your test and monitoring requirements.

Infrared radiation thermometers

Infrared radiation thermometers measure temperature without contact. The object being measured constantly broadcasts information about its temperature.

Flow measurement devices

Flow measurement is accomplished by a variety of means, depending upon the quantities, flow rates and types of fluids involved. Many industrial-process flow measurements consist of a combination of two devices: a primary device that is placed in intimate contact with the fluid and generates a signal, and a secondary device that translates this signal into a motion or a secondary signal for indicating, recording, controlling or totalising the flow.

Other devices indicate or totalise the flow directly through the interaction of the flowing fluid and the measuring device that is placed directly or indirectly in contact with the fluid stream.

Fire survival cable system

The Pyrotenax mineral-insulated fire survival cable system possesses unsurpassed fire survival properties, being capable of carrying current at temperatures in excess of 1,000ºC. It is fireproof, waterproof and radiation-resistant, has a high corrosion resistance, is non-ageing and has great mechanical strength.

These properties enable Pyrotenax to be used in a variety of domestic, commercial and industrial applications, including car parks, shopping complexes, hotels, road and rail tunnels, airports, petrol stations and water treatment facilities.
