GEMCO Product Lines We Repair
Our engineers are trained on the full GEMCO product range. Below are the major product families we service.
Analog Panel Meters & Indicators
GEMCO's 2-inch and 3-inch analog panel meters for voltage, current, temperature, and pressure indication. Common issues include pointer stiction, zero drift, scale non-linearity, and movement bearing wear in high-vibration environments.
Temperature & Pressure Transmitters
4-20mA output transmitters for RTD, thermocouple, and pressure inputs. Typical faults include calibration drift, millivolt signal loss, output clamping, and transmitter terminal oxidation in humid industrial environments.
Signal Isolators & Conditioners
Galvanic isolators and signal conditioners for noisy plant floors. Common problems include isolation barrier failure, input-to-output linearity loss, power supply ripple, and DIN rail mounting contact corrosion.
Process Controllers & Logic Units
Single and multi-channel process controllers with setpoint, alarm, and output logic. Repair issues include relay contact wear, potentiometer shaft corrosion, hysteresis degradation, and PID tuning reset.
Digital Display & Readout Units
LED and LCD digital displays for process parameters, batch counters, and rate indication. Common faults include segment failure, decimal point dimming, multiplexing errors, and RS-485 communication dropouts.
Power Supplies & Accessories
Regulated 24VDC and dual-rail power supplies for GEMCO instruments and panel-mount electronics. Failures include capacitor dry-out in high-temperature areas, voltage regulation drift, and crowbar protection triggering.

Common GEMCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GEMCO equipment arriving at our workshop.
- ✓Analog meter zero drift and non-linearity — Pointer bearing wear, coil spring relaxation, and magnet degradation in GEMCO analog movements. High-vibration cement, steel, and power plants accelerate bearing friction and mechanical hysteresis.
- ✓Temperature transmitter calibration shift and millivolt loss — RTD element aging, input thermowell oxidation, and signal conditioning capacitor value drift in T-Series transmitters. Indian humidity and plant temperature cycling degrade internal reference standards and first-stage amplifier biasing.
- ✓4-20mA transmitter stuck at 3.8mA or rail values — Saturation of output amplifier stage in GEMCO transmitters due to input overload, or loss of negative supply rail (-12V or -15V). Also caused by transmitter terminal short circuits and moisture ingress into output driver IC.
- ✓Signal isolator barrier capacitance degradation or inter-channel crosstalk — Aging of isolation coupling capacitors and transformer winding insulation in GEMCO ISO-series isolators. Exposure to plant temperature swings (cold storage, blast furnace area, steam plants) causes dielectric breakdown and leakage current increase.
- ✓Digital display segment or decimal point failure — LED or LCD driver IC failure in GEMCO DRU and LCD-series units. Multiplexing row/column decode errors and segment driver transistor burnout from overcurrent or reversed polarity power connection.
- ✓Process controller relay contact pitting and hysteresis drift — Arc erosion from switching inductive loads (solenoid valves, contactors) on relay contacts in GEMCO PC-series controllers. Setpoint potentiometer shaft oxidation and coil insulation degradation from thermal cycling cause threshold creep and relay chatter.

Frequently Asked Questions — GEMCO Repairs
Do you repair GEMCO equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full GEMCO product range — analog meters, temperature and pressure transmitters, signal isolators, process controllers, digital displays, and power supplies. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and 50+ other cities. All repairs are completed at our ISO-certified facility in Vadodara, Gujarat.
What is the typical turnaround time for GEMCO transmitter repairs?+
Standard turnaround is 5-7 working days for GEMCO temperature and pressure transmitter repairs, including calibration and testing. Critical repairs (emergency breakdown support) are handled within 24-48 hours. We provide free courier pickup and delivery across India, and offer on-site support for large multi-unit installations in major manufacturing hubs.
Can Synchronics recalibrate GEMCO meters and transmitters to NIST standards?+
Yes. All GEMCO repairs at Synchronics include NIST-traceable calibration using certified dry-block calibrators, precision pressure standards, and calibrated millivolt sources. We issue individual calibration certificates with measurement uncertainty data, ideal for pharma, food safety, and quality-critical process applications across Indian plants.
Do you repair older GEMCO analog meters and vintage controllers no longer in production?+
Absolutely. Synchronics specializes in restoring legacy GEMCO analog panel meters, vintage process controllers, and discontinued signal conditioners. Many Indian cement plants, steel mills, and refineries still operate 1980s and 1990s GEMCO instrumentation. We source obsolete components, rewire connections if needed, and restore full accuracy — extending equipment life at a fraction of replacement cost.
What warranty do you provide on repaired GEMCO equipment?+
All GEMCO repairs carry a 12-month comprehensive warranty against component failure and calibration drift. If a repaired unit fails within warranty, we repair or replace it at no charge. We maintain spare inventory of common GEMCO modules and replacement parts, ensuring fast resolution and minimal downtime for your plant operations.
How do I send my GEMCO unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a GEMCO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on GEMCO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your GEMCO unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
