Sensor Cable - Assemblies

Sensor cables assemblies are a combination of cables and components designed to transmit information within a system and make it possible to measure various variables. A sensor assembly comprises several different components, including a sensor cable and a variety of other components, such as a baseplate, mounting brackets, and plugs. Sensor cables and assemblies typically have a limited range of energy losses, though, depending on the type of sensor being used, more efficient cables and assemblies are available.

Types of Sensor Cables

Sensor cables are typically categorised into three different types, namely parallel, multi-conductor, and coaxial cables. Parallel cables consist of two insulated conductors, which are parallel to each other and can be quickly and cost-effectively connected to other components. Multi-conductor cables, on the other hand, usually include more than two insulated conductors, which are insulated from each other and can equally be connected to other components. Coaxial cables, on the other hand, house a single conductor, which is surrounded by an outer conductive wall, and that is used to reduce noise and other interferences.

Sensor Cable Assembly Components

The components used in the assembly of a sensor cable can vary depending on the application and the type of sensor or connector used. Common components include a connector or cable housing, terminal hardware, a baseplate, mounting brackets, and rubber weather seals. Connector housings are usually customised and designed to fit a particular application, and can range from traditional metal housings to waterproof plastic mouldings. Terminal hardware is used to connect the cable to the signal source or destination and can range from electronic soldered connections to crimped terminals.

The Working Principle

Sensor cables are used to detect a wide range of physical and chemical parameters by providing an electrical signal to the device measuring the parameter. The electrical signal is generated by a transducer, which converts the detected parameter into an electrical signal. The signals generated by the transducer are sent to the measurement device, where the signals are processed and converted into the corresponding digital form. The measurement device typically consists of a circuit board that contains amplifiers and other electronic components. The circuitry functions to detect and amplify the signal from the transducer and convert it into digital form.

Applications

Sensor cables and assemblies are commonly used in a wide variety of industries including automotive, medical, and industrial markets. For example, automotive systems often use sensor cables to detect fuel pressure, brake pressure, and engine temperature. In medical markets, sensor cables and assemblies can be used to detect blood pressure, pulse rate, heart rate, and other vital signs. Industrial markets commonly rely on sensor cables and assemblies to detect temperatures, presence of specific gases, fluid pressures, and fluid levels.

Conclusion

Sensor cables and assemblies are a vital component of many electronics systems, providing a reliable connection between sensing elements, devices, and networks. Despite the limited range of energy losses associated with sensor cables and assemblies, more efficient cables and assemblies are available depending on the application and the type of sensor being used. Sensor cables and assemblies are widely used in automotive, medical, and industrial systems for the detection of a variety of physical and chemical parameters.
