Mineral Insulated Cable Routing Strategies for High Temperature Mould Telemetry
Recessed MI cable routing with thermal expansion loops prevents wire pinch, shields noise, and eliminates press downtime in high-temperature moulds.
Telemetry Routing
Meaning
Systematic planning of cable paths ensures the reliable transmission of data from sensors to control units. Strategic telemetry routing prevents electrical noise from interfering with delicate signals such as thermocouple voltages or pressure readings. This layout separates low voltage signal lines from high power heater cables within the mould framework.
Physical limits of the wiring channels and the maximum allowable signal attenuation define the boundary of this practice.
Signal Integrity
Shielding and separation minimize the impact of electromagnetic induction on the data streams. Proper telemetry routing reduces the occurrence of false temperature readings that can lead to part defects. Using twisted pairs within these routes further protects the information from external interference.
Thermal Protection
Sensors must be kept away from the direct heat of the manifold to avoid premature failure. Correct telemetry routing places the sensitive wires in cooled or insulated channels. This precaution ensures that the insulation on the signal wires does not melt or become brittle over time.
Cable Management
Orderly arrangement of the wires facilitates easier troubleshooting and replacement during maintenance. Telemetry routing often involves the use of specialized clips or trays to secure the cables against vibration. A well organized layout prevents the pinching of wires when the mould plates are assembled.
