Field Instrumentation Technician – Blenders, Mixers

The Field Instrumentation Technician (Mid-Level) is responsible for executing the installation, calibration, testing, troubleshooting, and maintenance of instrumentation systems integrated with industrial mixers, blenders, and allied equipment. This role involves working with PLC/DCS systems, ensuring compliance with safety and GMP standards, and maintaining instrument accuracy to support consistent batch quality and plant efficiency.

Key Responsibilities:

• Install, commission, and calibrate instrumentation systems for process equipment like mixers, blenders, tanks, and agitators.

• Troubleshoot faults in field devices such as RTDs, pressure transmitters, level sensors, VFDs, torque and load cells.

• Perform scheduled preventive and predictive maintenance (PM/PdM) on instruments related to mixing operations.

• Execute loop checks and signal verification for analog and digital I/O connected to control systems (PLC/SCADA/DCS).

• Maintain and update instrumentation documentation, including calibration certificates, loop diagrams, and work orders.

• Collaborate with control engineers, electricians, and mechanical teams during breakdowns and equipment shutdowns.

• Assist in validation and qualification activities (IQ/OQ/PQ) for newly installed or modified blending systems.

• Ensure compliance with GMP, GEP, and safety protocols, especially in regulated environments like pharma or food.

Key Focus Areas:

1. Instrumentation on Mixing Equipment

   • Install and maintain:

     • Sensors for temperature, pressure, and level in jacketed blenders or tanks

     • Load cells, torque sensors, and speed monitors on agitator shafts and motors

     • Vibration monitoring on high-speed mixing equipment

2. Calibration & Troubleshooting

   • Perform:

     • In-situ and bench calibrations using tools like Beamex, Fluke, or equivalent

     • Diagnosis of drift, signal loss, or false readings and corrective action implementation

3. Control System Interface

   • Understand:

     • Signal transmission (4-20 mA, 0-10V, HART/Modbus)

     • Wiring and terminations for integration into PLC/DCS panels

4. Documentation & SOP Compliance

   • Complete:

     • Calibration logs, maintenance records, and job cards

     • Work under GDP and maintain instrument traceability as per QA protocols

5. Safety & Operational Integrity

   • Follow:

     • Lockout/Tagout (LOTO), confined space, and electrical safety norms

     • SOPs aligned with process safety and hygiene requirements

Qualifications:

• Education:

  • ITI / Diploma in Instrumentation, Electrical, Electronics, or Mechatronics

• Experience:

  • 3 to 6 years in field instrumentation maintenance or project commissioning

  • Hands-on experience with batch-based process equipment preferred

• Technical Skills:

  • Competent in working with:

    • RTDs, thermocouples, transmitters, proximity switches, VFDs

    • Calibrators, multimeters, and field communicators (e.g., HART)

    • Basic PLC/DCS knowledge for troubleshooting I/O issues

• Soft Skills:

  • Team player with good communication and problem-solving skills

  • Able to interpret P&IDs, loop drawings, and OEM manuals
