Loop Testing Technician – CIP/SIP and Process Zones

The Junior Loop Testing Technician is responsible for assisting in the execution and documentation of loop testing, signal verification, and functional checks of process instrumentation in CIP/SIP systems and process zones. This includes supporting calibration teams and validation engineers in ensuring that all instruments function correctly within their defined control loops and meet regulatory standards.

Key Responsibilities:

• Assist in performing loop checks between field instruments (e.g., transmitters, sensors) and control systems (PLC/DCS).

• Verify proper installation, polarity, signal range, and tagging of sensors during loop tests.

• Conduct signal simulation and continuity checks using loop calibrators or HART communicators.

• Support pre-commissioning and commissioning activities in CIP/SIP skids, reactors, mixing vessels, and transfer lines.

• Document loop test results, deviations, and corrections in standard forms or digital systems.

• Ensure compliance with GMP, safety protocols, and cleanroom practices during testing.

• Collaborate with electrical, automation, and QA validation teams during qualification activities (IQ/OQ).

Key Focus Areas:

1. Loop Integrity Testing

   • Check and document:

     • Signal continuity from instrument to PLC/DCS

     • 4-20 mA / digital signal accuracy and polarity

     • Alarm verification and scaling range testing

2. Instrumentation in CIP/SIP Zones

   • Work on loops involving:

     • RTDs, thermocouples, pressure transmitters, conductivity sensors, flow meters used in cleaning and sterilization systems

3. Support for Commissioning & Qualification

   • Assist in:

     • Pre-loop checks, signal verification, I/O list validation, and support for IOQ documentation

4. GMP & Safety Compliance

   • Adhere to:

     • Good Documentation Practices (GDP), LOTO procedures, area gowning protocols, and safety checklists

5. Coordination & Documentation

   • Collaborate with:

     • Instrumentation engineers, validation specialists, and project teams

   • Maintain loop test logs, punch lists, and update as-built drawings (with guidance)

Qualifications:

• Education:

  • Diploma or ITI in Instrumentation, Electrical, Electronics, or related field

• Experience:

  • 0–2 years of experience in instrumentation testing or project commissioning

  • Freshers with project/internship experience in instrumentation or pharma/food commissioning can apply

• Technical Skills:

  • Basic knowledge of:

    • Loop testing tools (e.g., multimeter, loop calibrator)

    • Instrument types and signal types

    • Reading loop diagrams, wiring schedules, and P&IDs (basic level)

• Soft Skills:

  • Attention to detail, discipline in documentation, willingness to work in cleanroom/GMP environments

  • Strong learning attitude and teamwork
