BAILEY Product Lines We Repair
Our engineers are trained on the full BAILEY product range. Below are the major product families we service.
INFI 90 Distributed Control System
BAILEY's flagship DCS platform for large-scale process automation. Common repairs include CPU module failures, communication card faults, analog input/output card drift, and power supply degradation affecting control loop stability.
BAILEY Analog Transmitters and Transducers
Pressure, temperature, flow and level transmitters used throughout Indian refineries and chemical plants. Repair addresses zero/span drift, signal loss, failed electronics modules, and connector corrosion in harsh industrial environments.
BAILEY Pneumatic Controllers and Instruments
Legacy pneumatic control valve positioners, indicating controllers and recording instruments still operational in many Indian plants. Repairs include diaphragm replacement, nozzle-flapper calibration, and bellows seal restoration.
BAILEY Hart Communications Interface
Intelligent transmitter interfaces and gateways enabling HART protocol communication. Failures include firmware corruption, power module degradation, and signal isolation failures disrupting asset management networks.
BAILEY PLC and Logic Solver Modules
Compact logic controllers and safety-rated PLCs for process interlocks and emergency shutdown systems. Common faults: processor failures, relay card wear, memory corruption, and input/output scan timeout errors.

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 BAILEY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BAILEY equipment arriving at our workshop.
- ✓INFI 90 CPU module no-boot or repeated restart — BAILEY INFI 90 processors experience power supply regulation failures causing insufficient voltage to CPU microprocessor during cold start. Capacitor dry-out on PSU and clock crystal oscillator failure are common age-related issues in Indian heat and humidity conditions.
- ✓Analog input card shows erratic sensor readings or stuck values — BAILEY analog I/O cards suffer from input amplifier offset drift, ADC non-linearity, and coupling capacitor aging — especially in high-temperature or vibration-prone petrochemical environments common in Indian refineries. Solder cold joints on signal conditioning circuits also cause intermittent channel loss.
- ✓Communication module cards not responding or protocol timeout errors — BAILEY INFI 90 communication cards (Ethernet, serial, proprietary BLU-LINK) fail due to transformer/isolation driver IC burnout, firmware corruption, or connector pin oxidation. High-voltage transients and poor grounding in Indian industrial plants accelerate failure.
- ✓Pressure or temperature transmitter reading drifts gradually or fails completely — BAILEY analog transmitters suffer zero/span drift from sensor aging, PCB moisture ingress, potentiometer wear, and failed output amplifier stages. In Indian plants with salt-air or corrosive atmospheres, connector corrosion causes signal loss and intermittent operation.
- ✓Pneumatic positioner diaphragm rupture or slow response to command signal — BAILEY Model 60/67 pneumatic positioners experience diaphragm material brittleness and perforation after 15-20 years in high-temperature process lines. Nozzle-flapper assembly wear causes hysteresis and sluggish valve positioning affecting process control accuracy.
- ✓HART transmitter not communicating or showing garbled configuration data — BAILEY HART interface modules experience microprocessor brownout, EEPROM corruption, or modem IC failure. Dirty signal lines and inadequate 24 VDC power supply voltage cause communication protocol errors in multi-transmitter networks common in Indian chemical plants.

For critical plant shutdowns, Synchronics offers emergency 24-48 hour repair service with expedited return by courier. We maintain backup INFI 90 CPU modules available for immediate temporary exchange if needed for business continuity.
Can you repair BAILEY transmitters that are out of calibration or showing zero drift?+
Absolutely. Synchronics specializes in BAILEY transmitter recalibration using precision reference standards. We offer zero-span adjustment, linearity compensation, and environmental compensation recalibration for pressure, temperature, flow, and level transmitters. All transmitters are returned with multi-point calibration certificates traceable to ISM standards, required for compliance audits in Indian refineries and pharmaceutical plants.
Do you have spare parts in stock for obsolete BAILEY components?+
Yes. Synchronics maintains a significant inventory of BAILEY spare cards, modules, connectors, and electronic components sourced from authorized distributors and salvage. For obsolete INFI 90 cards and pneumatic instrument parts, we work with Indian and international suppliers to locate genuine replacements. We also provide component-level repairs — replacing failed ICs, capacitors, and transistors — to restore obsolete modules to working condition.
Are you authorized by BAILEY/Emerson for repair work?+
Synchronics is an authorized independent service provider with deep expertise in BAILEY control systems, transmitters, and legacy instruments across Indian industries. We maintain technical documentation, calibration standards, and testing equipment aligned with BAILEY/Emerson service specifications. All repairs are documented with technical reports for plant maintenance records and regulatory compliance.
