Sensor Wiring Technician – Temperature, Proximity, Hall Effect

The Mid-Level Sensor Wiring Technician is responsible for independently executing the installation, wiring, and basic testing of field sensors such as RTDs, thermocouples, proximity sensors, and Hall Effect devices. The role includes ensuring proper routing, termination, and signal integrity in support of instrumentation and control system readiness.

Key Responsibilities:

• Sensor Installation & Wiring:
  Install and wire a variety of sensors (temperature, proximity, Hall Effect) according to datasheets, wiring diagrams, and site layouts.

• Cable Routing & Termination:
  Perform precise routing and termination of sensor signal cables in field junction boxes and control panels, ensuring correct labeling and shielding.

• Drawing Interpretation:
  Read and interpret P&IDs, instrument hook-up drawings, cable schedules, and termination diagrams accurately.

• Continuity & Polarity Checks:
  Conduct basic functional checks, continuity tests, and polarity verification of wired sensors before commissioning or loop checks.

• Quality Compliance:
  Adhere to industry standards and project specifications in all wiring work, ensuring signal integrity and environmental protection.

• Field Coordination:
  Coordinate with electricians, instrument fitters, and control system teams to align sensor installation with mechanical and electrical works.

• Troubleshooting Support:
  Identify and resolve basic wiring issues such as open circuits, grounding faults, or incorrect terminations.

• Safety Practices:
  Ensure compliance with site safety standards (PPE, LOTO, hazard awareness) during all wiring activities.

Focus Areas:

1. Precision in Termination:
   Ensure high-quality, accurate wiring of sensors, using ferrules, proper insulation, and effective signal shielding techniques.

2. Signal Reliability:
   Maintain clean signal transmission through proper grounding, shielding, and cable management for analog and digital sensors.

3. Documentation & Updates:
   Assist in updating redline drawings and installation records to reflect as-built conditions.

4. Support for Testing & Commissioning:
   Prepare sensors and wiring for pre-commissioning and loop check activities, ensuring zero wiring-related punch points.

5. Continual Skill Development:
   Deepen technical knowledge of sensor technology, industrial wiring codes (e.g., IEC, NEC), and control system interfaces.

Qualifications:

• ITI, Diploma, or Technical Certification in Electrical, Electronics, or Instrumentation.

• 2–5 years of experience in sensor installation, industrial wiring, or instrumentation cabling.

• Proficient with temperature sensors (RTD, thermocouple), inductive/capacitive proximity sensors, and Hall Effect sensor systems.

• Ability to use multimeters, hand tools, and sensor testing equipment.

• Solid understanding of analog/digital signals and sensor wiring best practices.

• Team-oriented with effective communication and documentation skills.

• Familiarity with site safety standards and electrical installation codes (ISA, IEC, NEC).
