Here at Intech we have a large variety of sensors for many different industries and
applications, but the most common measurement sensor that is shipped from our
stores is the temperature probe. Not only is temperature the most common value
of interest, but Intech stocks New Zealand’s largest range of probes to suit every
application imaginable. Special probes can manufactured to suit your application – just contact us with your requirements.
RTDs are by far the most accurate temperature probe type available (±0.15°C), with a typical temperature range of -200~300°C.
The most commonly used RTD is the Pt100, so named due to the fact that the element material is usually Platinum (chemical symbol ‘Pt’), and because at a temperature of 0°C it provides an electrical resistance of 100ohms.
Without getting too technical, thermocouples are very simple devices that operate via the principle ‘thermoelectric effect’; two different alloys that produce a voltage
proportional to a temperature difference.
Thermocouples with ‘Compression Fitting MTH-LH’ tend to be popular because they are inexpensive, interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures; -185 to 2,320°C.
However we recommend RTD’s for more accurate temperature readings below 500°C
