TBF Equipment We Repair — By Category
TBF Product Lines We Repair
Our engineers are trained on the full TBF product range. Below are the major product families we service.
Temperature Transmitters (2-Wire & 4-Wire)
Precision TBF transmitters convert RTD and thermocouple signals to standardised 4-20mA or Hart digital outputs. Common failures include zero drift, span errors, cold-junction compensation faults, and Hart communication breakdowns in high-vibration environments.
Thermal Switches and Limit Controllers
TBF bimetal and electronic thermal switches provide over-temperature protection in motors, transformers, and process equipment. Failures stem from contact wear, calibration drift, setpoint loss, and corrosion in humid industrial environments.
RTD and Sensor Assemblies
TBF resistance temperature detectors (Pt100, Pt1000) and sensor probes with thermowell protection for harsh plant conditions. Repair challenges include wire breakage, sheath corrosion, connector looseness, and insulation breakdown from moisture ingress.
Hart Protocol Signal Conditioning
TBF Hart-enabled transmitters and gateways for Industry 4.0 integration and predictive maintenance. Faults include protocol timeouts, EEPROM corruption, power supply instability, and failed communication transducers.
Signal Isolators and Converters
TBF galvanic isolation and signal conversion modules protecting control systems from ground loops and noise in petrochemical and steel plants. Common defects: transformer core saturation, optocoupler failure, and precision resistor drift.
Process Data Loggers and Recorders
Compact TBF data acquisition units for temperature, pressure, and analogue signal monitoring and trending. Failures include SD card corruption, LCD failure, battery backup depletion, and sensor input channel shorts.
Why Choose Synchronics for TBF Repairs?
PCB-Level Expertise

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common TBF Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TBF equipment arriving at our workshop.
- ✓TBF transmitter 4-20mA output stuck low — Power supply dropout, internal DAC failure, or Hart communication lockup in the transmitter microcontroller. Often triggered by EMI spikes from VFD or contactor switching near the sensor cable.
- ✓TBF RTD resistance reading drifts 5-10 ohms per hour — Cold-junction compensation error in two-wire transmitter, or moisture ingress into sensor sheath causing insulation degradation. Thermal cycling amplifies Pt100 wire annealing in low-quality sensor assemblies.
- ✓TBF thermal switch fails to actuate at setpoint — Bimetal strip metal fatigue from repeated cycling, calibration drift due to spring relaxation, or contact oxidation preventing electrical continuity. Common in steam line applications with 50+ actuations per day.
- ✓TBF Hart transmitter loses communication every 30-60 seconds — UART transceiver IC (like MAX485) failing under temperature stress, or Hart modem firmware crash from noise-induced bit errors. Root cause often inadequate shield grounding in field wiring.
- ✓TBF signal isolator output saturated at rail voltage — Input transformer core saturation from DC offset component, or failed feedback amplifier in the precision output stage. Capacitor drying on primary side also reduces coupling coefficient.
- ✓TBF data logger SD card unrecognised or corrupted files — File system corruption from improper shutdown during write cycle, or SD card mechanical wear after 10,000+ insertion cycles. Power supply glitches also corrupt FAT tables.

Frequently Asked Questions — TBF Repairs
Do you repair TBF equipment anywhere in India?+
Yes. Synchronics repairs the complete TBF thermal measurement and process control product range — transmitters, thermal switches, RTD sensors, Hart modules, signal isolators, and data loggers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other major cities. All repairs completed at our ISO 9001 certified facility in Vadodara, Gujarat, with calibration certificates and warranty.
What is the typical turnaround time for TBF transmitter repair?+
Standard repairs (power supply, DAC failure, signal conditioning) are completed within 5-7 working days including full calibration and Hart protocol verification. Complex issues like EEPROM reprogramming or sensor head replacement may extend to 10-12 days. We offer 48-hour express service for critical production equipment — contact our dispatch team for priority quotation.
Can you repair TBF Hart transmitters with protocol issues or communication timeouts?+
Absolutely. Synchronics specialises in TBF Hart diagnostics and repair. We have HART Foundation certified software to reprogram transmitters, test protocol handshakes, and verify digital variable mappings. We also repair failed Hart transceiver ICs (MAX485, MAX490), replace corrupted EEPROM, and test communication across noise-laden industrial environments. Full Hart diagnostic report provided with each transmitter.
Do you stock TBF spare parts and components?+
We maintain a stock of common TBF replacements including power supply modules, op-amp ICs, RTD sensor probes, bimetal elements, and digital display modules. For custom or obsolete parts, we coordinate directly with TBF distributor network across India or source equivalent components with OEM cross-reference. Lead time for special parts typically 10-15 business days.
What documentation and warranty do you provide after TBF repair?+
Every repaired TBF unit receives a detailed technical report documenting fault diagnosis, components replaced, test results across full operating range, and a calibration certificate traceable to NIST standards. We provide 12 months warranty on all labour and replaced components. For high-reliability applications (pharma, oil and gas), we offer extended 24-month warranty and quarterly performance audits at cost.
How do I send my TBF 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 TBF 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 TBF 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 TBF 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.
