RTDs & Thermocouples, Temperature Probes
More Information
Resistive Thermal Devices (RTD's: Pt100s etc)
and T/C type K, J, T etc
Resistive thermal devices (RTDs) are also called resistance thermometers or resistance temperature detectors. They are temperature sensors that exploit the predictable change in electrical resistance of some materials with changing temperature.
Thermocouples made of 2 dissimilar metals and produce a millivolt signal in proportion to temperature.
We manufacture a wide range of temperature sensors and also offer mineral insulated thermocouples as small as 0.5mm in diameter and Pt100 sensors down to 1.6mm diameter.
For designs not covered by this listing please refer to the customisable temperature sensor section.
Temperature sensors
Our range of temperature sensors includes numerous designs found on well-known brands of machines throughout the world. The construction and materials have been carefully matched to satisfy the requirements of general as well as plastics and packaging industries.
There are two sensor families:
- RTDs which change resistance in proportion to temperature
- Thermocouples made of 2 dissimilar metals and produce a millivolt signal in proportion to temperature.
Thermocouples can be made in small sizes and their measuring points are well defined (ie. good for surface measurements). Generally, RTD’s are not as compact as thermocouples, are less suitable for surface measurements, but ideal for when accuracy is critical.
Quick delivery time & replacements
Our manufacturing system is tailored for quick delivery time and flexibility. Recognising the cost of downtime of machines, we offers a "SOS" service, manufacturing and dispatching replacements within a few hours after receipt of the order.For selection and ordering
Drawings and product codes of frequently used temperature sensors have been compiled on the following pages for ease of selection and ordering. In addition,we offer mineral insulated thermocouples in diameters down to 0.5mm and Pt 100 sensors down to 1.6mm.
Ordering: Please indicate the appropriate stock code when ordering. Sensors are supplied with a label attached to the cable, stating the part number, batch reference and sensor code.
We manufacture all types of temperature sensors to customers specifications. Please contact us with your requirements if none of the standard sensors fit your application.
