What are the Challenges of Instrument Signal Lines?
Instrument signal lines are essential for the measurement and control of various process parameters, such as flow, pressure, temperature, level, etc. However, instrument signal lines also face some challenges that can affect their performance and reliability. Some of the challenges are:
EMI: As mentioned earlier, EMI is a disturbance that affects an electrical circuit due to electromagnetic induction, electrostatic coupling or conduction. EMI can cause unwanted signals or noise in the instrument signal lines, which can affect the accuracy, reliability and safety of the measurement and control systems.
Corrosion: Corrosion is the deterioration of a material due to chemical or electrochemical reactions with its environment. Corrosion can affect the integrity and functionality of the instrument signal lines, especially in harsh environments, such as high temperature, high pressure, high humidity, acidic or alkaline conditions, etc.
Mechanical damage: Mechanical damage is the physical damage caused by external forces, such as impact, abrasion, vibration, bending, twisting, etc. Mechanical damage can cause cracks, breaks, cuts or deformation of the instrument signal lines, which can result in signal loss or leakage.
Thermal expansion: Thermal expansion is the change in length or volume of a material due to changes in temperature. Thermal expansion can cause stress and strain on the instrument signal lines, which can lead to sagging, buckling or rupture.
How to Overcome the Challenges of Instrument Signal Lines?
To overcome the challenges of instrument signal lines, it is important to follow the requirements and recommendations of Shell Dep 32.37.20.10 for the design and engineering of instrument signal lines. Shell Dep 32.37.20.10 provides guidance on how to select the appropriate type of cable, shielding, grounding, routing and termination for the instrument signal lines, depending on the level of EMI exposure and the criticality of the system.

What are the Types of Instrument Signal Lines?
Instrument signal lines can be classified into different types based on their function, configuration and characteristics. Some of the types of instrument signal lines are:
Analog signal lines: Analog signal lines are used to transmit continuous signals that vary in amplitude and frequency, such as voltage, current or resistance. Analog signal lines are typically used for low-frequency and low-accuracy applications.
Digital signal lines: Digital signal lines are used to transmit discrete signals that have only two states, such as on or off, high or low, or 1 or 0. Digital signal lines are typically used for high-frequency and high-accuracy applications.
Coaxial cables: Coaxial cables are a type of shielded cable that consists of a central conductor surrounded by an insulating layer and a metallic shield. Coaxial cables are used to transmit high-frequency signals with minimal interference and attenuation.
Twisted pair cables: Twisted pair cables are a type of cable that consists of two insulated conductors twisted together. Twisted pair cables are used to reduce the interference and crosstalk between the conductors.
Fiber optic cables: Fiber optic cables are a type of cable that consists of one or more thin strands of glass or plastic that transmit light signals. Fiber optic cables are used to transmit high-speed and high-bandwidth signals with minimal loss and distortion.
