45103 BK005 Cables, Wires

Multiple Conductor Cables encompass a range of categories, such as coaxial cables for television, control cables for automation networks, and non-shielded cables for other electrical applications. 45103 BK005 belongs to the non-shielded cable family; made with a single extended conductor, it can mainly be found among power transmission lines, instrumentation applications, and in general, all the systems where temperature monitoring is key. In this article, the application field and working principle of 45103 BK005 will be addressed.

45103 BK005 is a single-conductor cable composed by a polyvinyl chloride (PVC) insulation and a stranded bare copper conductor. It offers the advantages of being lightweight, easy to install, and strong resistance against extreme temperatures ranging from -20°C to 80°C. Additionally, it has excellent flexibility and is resistant to sunlight, oils and other chemicals. Such features make 45103 BK005 a preferred choice for a multitude of vector and scalar sensing applications.

Among the places where 45103 BK005 is the preferred choice of cable are those that require temperature monitoring, particularly in closed or high-density installations. The most common examples are industrial equipment, domestic appliances, and cooling systems that need to be monitored accurately in order to ensure proper functioning. Additionally, the cable is a preferred choice for exterior installations, due to its good finish that helps to protect the conductor against elements like water, dust and heat, as well as its flexibility for tight locations.

The working principle of 45103 BK005 is based on the generation of an electro-voltage signal proportional to the temperature: a platinum Resistance Temperature Detector (RTD) generates a static electric potential that is a function of temperature, and proportional to the temperature. This creates a resistance gradient along the cable, measuring the difference in current flow at various points, and resulting in an analog signal.

This signal needs to be properly conditioned for it to become useful: a primary signal processing device is used to convert the signal from the Proportional Temperature Detector (PTD) to a usable format. Then, a signal converter provides a means to transmit the signal to a control system, monitoring system, or a display. In the case of 45103 BK005, the signal converter would usually be a PT100A transmitter, capable of converting electric signals from a PTD to a standard 4...20mA signal.

In conclusion, 45103 BK005 is a single-conductor cable designed for temperature measuring applications. Its insulation and construction help it withstand extreme temperatures raging from -20°C to 80°C; and its lightweight construction and flexibility make it ideal for tight or difficult-to-install places. The working principle is based on the generation of an electric potential proportional to the temperature, that is converted to a usable format with a PT100A transmitter before being sent to a control system or a display, allowing a record to be kept and operational parameters to be adjusted in real time.
