FRANKLIN INSTRUMENT Product Lines We Repair
Our engineers are trained on the full FRANKLIN INSTRUMENT product range. Below are the major product families we service.
Analog Panel Meters
Classic moving-coil and moving-iron analog meters for voltage, current, frequency, and power measurement. Common issues include needle drift, scale accuracy loss, coil burnout, and mechanical jamming from vibration or thermal cycling in industrial environments.
Digital Display Units
Multi-function digital indicators for process parameters including temperature, pressure, flow, and power readings. Typical faults include LED/LCD segment failure, calibration drift, input signal conditioning errors, and connector corrosion in humid manufacturing environments.
Signal Conditioner Modules
Precision analog-to-digital and signal conditioning modules for sensor-to-PLC integration. Common failures include input amplifier drift, reference voltage instability, isolation transformer breakdown, and PCB connector degradation from thermal stress.
Process Control Interfaces
Hardwired and software-configurable control interfaces linking sensors to automation systems. Repair issues involve relay contact pitting, solid-state output failure, communication protocol errors, and power supply regulation problems affecting measurement loop stability.
Transducer and Transmitter Modules
4-20mA and 0-10V transmitter modules converting physical measurements into standard industrial signals. Common faults include zero/span drift, excitation supply failure, non-linear output response, and connector water ingress in wet processing environments.

Common FRANKLIN INSTRUMENT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FRANKLIN INSTRUMENT equipment arriving at our workshop.
- ✓Analog meter needle stuck or erratic movement — Franklin Instrument moving-coil meters suffer needle jamming from accumulated dust, bearing corrosion, or magnetic core oxidation in high-vibration environments common in Indian textile mills, cement plants, and foundries. Thermal cycling also weakens jewel bearing suspension.
- ✓Digital display segments dark or intermittent — Franklin Instrument DPM and DPI series experience LED/LCD segment failure from thermal stress, inadequate potting in humid environments (common in coastal Indian manufacturing), or internal solder joint cracking from vibration. Supply voltage fluctuations also degrade display driver circuits.
- ✓Calibration drift - meter reads 5-15% off nominal — Franklin Instrument precision instruments lose calibration due to component aging, thermal drift in input amplifiers, reference voltage instability, and connector corrosion in multi-point plant installations. Indian industrial temperature swings and power quality issues accelerate drift in unshielded installations.
- ✓No signal output or 4-20mA transmitter stuck at 4mA — Franklin Instrument transmitter modules fail when excitation supply regulation collapses, reference amplifiers drift out of specification, or output stage solid-state switches short. Connector oxidation and control signal loss also prevent proper signal conditioning in industrial enclosures.
- ✓Intermittent communication or data corruption in PCI interface modules — Franklin Instrument PCI control interface modules experience protocol errors from serial communication line degradation, isolated ground loop issues in multi-equipment plant configurations, and microcontroller firmware corruption. Partial component failure in signal conditioning circuits also causes data inconsistency.
- ✓Water ingress and corrosion in connector pins and PCB traces — Franklin Instrument transducers and field-mounted transmitters deployed in Indian chemical plants, food processing, and water treatment facilities suffer connector corrosion from moisture infiltration, inadequate sealing, and repeated thermal cycling. Salt spray environments near coastal industrial zones accelerate copper oxidation.

Frequently Asked Questions — FRANKLIN INSTRUMENT Repairs
Do you repair Franklin Instrument equipment anywhere in India?+
Yes. Synchronics repairs the complete Franklin Instrument product range - analog meters, digital displays, signal conditioners, process control interfaces, and transmitter modules. We offer PAN India door pickup and drop-off from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, and all major industrial cities. All repairs are performed at our main facility in Vadodara, Gujarat, with 180+ engineers skilled in Franklin Instrument instrumentation.
Why is my Franklin Instrument analog meter showing inconsistent readings across temperature swings?+
Franklin Instrument analog meters contain temperature-sensitive components including moving-coil suspensions, magnetic cores, and spring assemblies. In Indian industrial environments with 15-40°C temperature variations, these components drift without proper compensation. Synchronics performs full thermal characterization, replaces degraded temperature-compensating components, and delivers recalibration data across the entire operating temperature range your plant experiences.
Can Franklin Instrument digital displays be repaired or must they be replaced?+
Most Franklin Instrument DPM and DPI digital display failures are repairable at board level. Synchronics replaces failed LED/LCD segments, restores display driver circuits, repairs power supply issues, and restores signal conditioning function. We repair approximately 85% of failed Franklin displays, avoiding costly full-unit replacement and downtime for Indian manufacturing plants.
What documentation does Synchronics provide after Franklin Instrument equipment repair?+
We provide detailed repair reports documenting faults found, components replaced, testing performed, and calibration data. All Franklin Instrument repairs include ISO 9001-compliant recalibration certificates with NIST traceability, measurement uncertainty statements, and before/after performance comparisons. Documentation supports your plant's quality audits and equipment maintenance records.
How long do Franklin Instrument meter recalibrations typically remain within specification?+
After Synchronics recalibration, Franklin analog meters typically maintain accuracy for 12-18 months in stable Indian industrial environments. Digital displays and transmitters may drift within 3-6 months due to amplifier aging and thermal effects. We recommend annual recalibration for critical measurement points in process control loops, especially in high-temperature or corrosive environments common in chemical, cement, and power generation industries.
How do I send my FRANKLIN INSTRUMENT 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 FRANKLIN INSTRUMENT 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 FRANKLIN INSTRUMENT 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 FRANKLIN INSTRUMENT 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.
