Thermocouples
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 2 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.

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 RTD's. They can be wired in either 2, 3, or 4 wire configurations.

Thermowells
Thermowells are among the simplest yet least well 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.

Food Industry Sensors
The temperature of food plays a big role in assuring that certain products are well enough cooked to kill harmful organisms like bacteria. The type of sensors needed for the measurement of temperature in the food and beverage industry need to be carefully constructed to ensure that there is no product buildup that can be a breeding ground for contaminating bacteria.

Glass Industry Sensors
Measuring temperature in the glass industry is one of the most demanding applications for the sensor manufacturer. Pyrosales has had many years of experience in all types of glass industry applications enabling us to offer the right sensor for these applications.

Pyrosales Pty Ltd, is a specialist manufacturer of standard and precision temperature measurement sensors and
Australia's largest manufacturer of thermocouples and resistance temperature sensors.
