BOURDON HAENNI GROUP Product Lines We Repair
Our engineers are trained on the full BOURDON HAENNI GROUP product range. Below are the major product families we service.
Bourdon Tube Gauges
Mechanical pressure measurement instruments using C-type or spiral bourdon tubes. Common issues include tube fatigue, pointer stiction, and glass face fogging. Synchronics recalibrates, replaces internal components, and tests across 0-600 bar range.
Electronic Pressure Transmitters
4-20mA and 0-10V output transmitters for SCADA integration. Repair involves sensor bridge recalibration, signal conditioning PCB replacement, and zero-span adjustment. Synchronics handles IP67-rated and explosion-proof variants.
Differential Pressure Indicators
Dual-gauge assemblies for filter monitoring and flow measurement in industrial systems. Issues include membrane rupture, gauge seal degradation, and electrical contact corrosion. Synchronics services all gauge pairs and associated instrumentation.
Digital Display Gauges
LCD/LED pressure readout instruments with integrated electronics and battery/mains supply. Common faults: display segment failure, sensor malfunction, battery circuit degradation. Synchronics repairs PCBs, replaces displays, and recalibrates sensor bridges.
Capsule and Diaphragm Gauges
Low-pressure measurement instruments (0-1 bar, 0-5 bar) for sensitive applications. Issues include capsule perforation, linkage wear, and pointer misalignment. Synchronics specializes in pharmaceutical and HVAC system repairs.

Common BOURDON HAENNI GROUP Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BOURDON HAENNI GROUP equipment arriving at our workshop.
- ✓Bourdon tube fatigue and mechanical creep — Repeated pressure cycling above rated specification or vibration-induced metal fatigue in the C-shaped tube. Over 10-15 years in high-cycle operations (compressor discharge, pump outlets), the tube loses elasticity and fails to return to zero.
- ✓Transmitter 4-20mA signal dropout and erratic output — Failed integrated amplifier IC, broken solder joints on sensor bridge PCB, or corroded cable terminations from moisture ingress. Common in coastal and humid industrial zones across Indian plants operating near water or steam lines.
- ✓Gauge pointer stiction and sluggish response — Bearing friction increased due to dust ingress through the threaded connection or pointer pivot bearing corrosion. Common in cement plants, steel mills, and sugar factories where abrasive air and chemical vapors contaminate the gauge.
- ✓Differential pressure gauge seal failure and fluid leakage — Elastomer gasket and membrane degradation due to age, thermal cycling, or incompatible pressure media (hydrogen sulfide, chlorine). Oil-filled gauges lose fill fluid through failed seals, causing vacuum formation and mechanism seizure.
- ✓Digital display LCD segment blackening and pixel dropout — Electrolytic corrosion of LCD segment drivers due to humidity and contaminated solder flux residue on the PCB. Thermal stress from extreme temperature swings in outdoor or furnace-adjacent mounting also causes segment failure.
- ✓Zero-point drift in electronic transmitter output — Sensor bridge imbalance caused by thermistor aging, reference voltage regulation failure, or mechanical stress on the capacitive or strain-gauge sensor element from mounting vibration or thermal gradient.

What is the typical turnaround time for Bourdon Haenni gauge calibration and repair?+
Standard repair and recalibration turnaround is 5-7 working days from receipt. Urgent repairs can be completed in 2-3 days at a priority service charge. All gauges are bench-tested and certified against traceable dead-weight testers before dispatch. Emergency on-site repair is available for critical plants in Gujarat and Maharashtra.
Can Synchronics repair Bourdon Haenni transmitters with 4-20mA and explosion-proof certifications?+
Yes. Synchronics is authorized to repair all Bourdon Haenni Type 330, 331, 332, and 333 transmitters including intrinsically safe and flame-proof variants. We maintain ISO/IEC 61010 test equipment, recalibrate sensor bridges, and replace failed amplifier modules. Post-repair, units undergo functional verification and are issued a certified calibration report valid for Indian plant compliance audits.
What happens if a Bourdon tube cannot be repaired and needs replacement?+
Synchronics stocks genuine Bourdon Haenni replacement tube assemblies for Types 111, 112, 113, 201, 202, and 213 gauges. If spare tubes are unavailable, we source them directly from the Bourdon Haenni network within 10-14 days. During this period, we can supply a calibrated rental gauge of equivalent range to keep your process operational, ensuring zero plant downtime.
Do you provide calibration certificates and ISO 17025 traceability for repaired Bourdon Haenni equipment?+
Yes. Every repaired and recalibrated Bourdon Haenni instrument is issued a detailed calibration certificate with full traceability to NIST/NPL standards. Certificates include measurement uncertainty, calibration date, next due date, and technician signature. Reports are compliant with ISO 9001, ISO 13485 (pharma), and ISO 50001 (energy) audit requirements across Indian industries.
