BANCROFT Product Lines We Repair
Our engineers are trained on the full BANCROFT product range. Below are the major product families we service.
Bancroft Pressure Transmitters
Precision 4-20mA and digital pressure transducers for process monitoring. Common failures include diaphragm rupture, amplifier circuit degradation, and seal leakage causing zero drift or non-linearity.
Bancroft Flow Measurement Systems
Electromagnetic and differential pressure-based flow meters with integrated display and relay outputs. Typical issues include electrode fouling, transmitter board failures, and calibration loss in hazardous area applications.
Bancroft Analog I/O Control Modules
Multi-channel analog input/output cards and signal conditioning modules for PLC and DCS integration. Repair needs include isolated channel failures, ADC converter errors, and relay contact welding.
Bancroft Process Control Units
Stand-alone controllers and data loggers for temperature, pressure, and flow regulation. Common faults include display LCD failure, internal power supply burnout, and sensor input circuit shorts.
Bancroft Hazardous Area Instruments
Intrinsically safe and explosion-proof transmitters for ATEX and IEC Ex Zone 1/2 applications in refineries and chemical plants. Failures typically stem from potting compound breakdown, barrier network failure, or zener diode degradation.
Why Choose Synchronics for BANCROFT Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on BANCROFT equipment.
Fast Turnaround
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 BANCROFT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BANCROFT equipment arriving at our workshop.
- ✓Bancroft pressure transmitter zero drift and non-linearity — Diaphragm stress relaxation, capacitive element aging, or internal fill fluid leakage over years of operation. Thermal cycling in Indian seasonal extremes accelerates this degradation.
- ✓Bancroft flow meter electrode polarization and signal dropout — Conductive deposits and mineral buildup on electromagnetic flow sensor electrodes in high-TDS water or corrosive process fluids common in Indian refineries and chemical plants.
- ✓Bancroft analog I/O card isolated channel failure — Electrostatic discharge damage, input overload beyond clamp voltage, or internal isolation coupling transformer saturation from DC offset in 4-20mA loop.
- ✓Bancroft control unit display LCD blackout or segment failure — LCD backlight inverter failure, internal LCD cell degradation from heat exposure, or ribbon cable intermittent contact after thermal shock cycles common in Indian foundries and steel plants.
- ✓Bancroft hazardous area transmitter zener barrier failure and sparking — Overvoltage transient during loop power surge, junction temperature exceeding thermal design in enclosed high-temperature environments, or manufacturing defect in zener die batch.
- ✓Bancroft power supply capacitor dry-out and output collapse — Electrolytic capacitor ripple current stress and thermal degradation in poorly ventilated control cabinets typical across Indian textile mills and pulp facilities experiencing high ambient temperatures.

Frequently Asked Questions — BANCROFT Repairs
Do you repair Bancroft equipment anywhere in India?+
Yes. Synchronics repairs the full Bancroft instrumentation and control product range—transmitters, flow meters, analog I/O cards, and process controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, Surat, and all major industrial centers. Complete repairs happen in our Vadodara, Gujarat facility with TAT of 3-7 working days for most units.
What Bancroft pressure transmitter models do you recalibrate to factory spec?+
Synchronics recalibrates all Bancroft PT series including PT-100, PT-200D, PT-500, DPT-100, and GPT-50 models. We perform full static calibration across 0-100% of nominal range using NIST-traceable pressure standards, verify 4-20mA loop accuracy to ±0.5%, and issue calibration certificates. Recalibration includes diaphragm replacement if necessary.
Can Synchronics repair Bancroft ATEX transmitters to maintain Zone 1 certification?+
Yes. Our engineers hold ATEX compliance expertise and repair Bancroft EX-PT-100, ATEX-FM-200, and IS-COND-50 hazardous area transmitters to reinstate intrinsic safety. We replace failed zener barriers, re-potted sensor heads, and test all units to ATEX Annex VIII barrier verification standards. We supply compliance documentation and certificates with every repair.
How do you handle Bancroft flow meter electrode cleaning for Indian high-mineral-content water?+
Synchronics uses proprietary chemical dissolution protocols to remove hardness deposits, biofilm, and corrosion scale from Bancroft electromagnetic sensor electrodes without damage. We then passivate surfaces, reassemble the measurement cell, and perform full flow simulation tests at multiple flow rates to verify linearity before shipment.
What is the typical cost and timeline for Bancroft analog I/O card repair in India?+
Repair cost for Bancroft AIO-16, AIO-32, or SIG-COND modules typically ranges 8,000-18,000 INR depending on component damage extent. Standard TAT is 4-5 working days. Expedited service available at 50% surcharge for 2-day turnaround. All repairs include full functional test on calibrated test benches and 12-month warranty.
How do I send my BANCROFT 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 BANCROFT 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 BANCROFT 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 BANCROFT 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.
