WIKA Equipment We Repair — By Category
WIKA Product Lines We Repair
Our engineers are trained on the full WIKA product range. Below are the major product families we service.
WIKA Bourdon Tube Pressure Gauges
Mechanical pressure measurement instruments widely used in steam systems, hydraulic lines, and compressed air networks. Common issues include pointer stiction, internal corrosion of wetted parts, and loss of accuracy due to mechanical wear or overpressure exposure.
WIKA Electronic Pressure Transmitters
4-20mA and 0-10V pressure transducers for industrial automation and PLC integration. Failures include signal drift, zero-point errors, 4mA output stalling, and capacitive sensor degradation in harsh chemical environments.
WIKA Temperature Sensors and Transmitters
Pt100 RTD, thermocouple, and electronic temperature transmitters used in furnaces, reactors, and heat exchangers. Common faults involve RTD element breakage, thermowell corrosion, transmitter zero drift, and connector oxidation in humid industrial settings.
WIKA Level and Process Control Instruments
Float-type, capacitive, and hydrostatic level measurement systems for tanks and vessels. Repair focuses on float mechanism stiction, capacitive probe fouling in chemical tanks, and pressure-level transmitter accuracy restoration.

Common WIKA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in WIKA equipment arriving at our workshop.
- ✓Pressure transmitter 4mA output stalling or zero drift — WIKA electronic transmitters experience 4mA hold faults due to capacitive sensor contamination in oily or chemical-laden process streams, or internal capacitor aging in humid industrial plants. Output drift occurs when the zero-pressure calibration point shifts due to temperature coefficient mismatch or power supply ripple.
- ✓Bourdon tube pointer lag or stiction in mechanical gauges — WIKA Bourdon tube gauges suffer pointer stiction when internal mechanical linkages accumulate corrosion deposits, or when the tube itself develops micro-fractures from overpressure spikes. Pointer lag is caused by friction in the pivot bearing or magnetic damping degradation.
- ✓Temperature sensor Pt100 element open circuit or resistance drift — WIKA RTD temperature sensors fail open-circuit due to mechanical vibration causing wire breakage inside the ceramic potting, or from thermal shock in furnace applications causing element fracture. Resistance drift occurs when the Pt100 wire surface oxidises or the thermowell accumulates scale deposits that insulate the sensing element.
- ✓WIKA transmitter signal loss after sudden power supply glitch or surge — WIKA electronic transmitters lose output or become non-responsive after mains supply glitches common in Indian industrial plants. This occurs due to transient voltage spikes exceeding the input protection circuit threshold, causing zener diode failure or microcontroller reset without clean startup sequencing.
- ✓Chemical attack and corrosion of gauge wetted parts and sensing diaphragms — WIKA instruments used in petrochemical, fertiliser, and caustic processing plants experience rapid corrosion of stainless steel wetted surfaces due to chloride ingress, sulfur compounds, or alkaline process liquids. Diaphragm material becomes brittle under sustained chemical exposure, leading to micro-cracks and leakage.
- ✓Inaccurate pressure or temperature readings due to calibration drift over time — WIKA transmitters and gauges drift out of accuracy specification due to cumulative thermal cycling in Indian monsoon climates, component aging (especially capacitors and resistor networks), and lack of preventive recalibration. Factory accuracy erodes gradually, making instruments non-compliant with ISO 9001 or ISO 17025 process control requirements.

Frequently Asked Questions — WIKA Repairs
Do you repair WIKA instrumentation anywhere in India?+
Yes. Synchronics repairs the complete WIKA product portfolio — pressure gauges, electronic transmitters, temperature sensors, and process control instruments. We offer PAN-India door-to-door pickup and return from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all tier-2 industrial cities. All repairs are completed in our Vadodara, Gujarat facility with precision test equipment and factory-equivalent quality standards.
How long does WIKA transmitter repair and recalibration take?+
Standard WIKA transmitter repair including diagnostics, component replacement, and recalibration takes 5-7 working days at Synchronics. Bourdon tube gauge mechanical restoration takes 3-5 days. We offer express 48-hour turnaround for critical temperature and pressure transmitters on request. All timelines include ISO 17025 calibration certificate generation and hydrostatic pressure testing.
Can Synchronics recalibrate WIKA instruments to our plant's specific range and accuracy class?+
Absolutely. Synchronics recalibrates WIKA pressure transmitters, gauges, and temperature sensors to your exact process range (e.g., 0-10 bar, 0-250 degC) and accuracy class (0.5%, 1%, 2.5%). We use multi-point calibration across the full operating range and provide NIST-traceable ISO 17025 certificates documenting all calibration data. We also advise on appropriate accuracy grades for your application — for example, level 0.5% for custody transfer, 1% for process control, 2.5% for alarm functions.
What is the typical cost of WIKA pressure transmitter repair versus replacement?+
WIKA transmitter repair at Synchronics typically costs 40-60% of new instrument cost, including diagnostics, component replacement, recalibration, and certification. For example, a failed WIKA S-20 electronic transmitter repair averages Rs 8,000-12,000 versus Rs 20,000-28,000 for new. We provide detailed quotations after initial inspection. Repair is most economical for transmitters under 5 years old; older instruments may warrant replacement depending on criticality and failure cause.
How do you handle WIKA Bourdon tube gauges that have been subjected to overpressure or mechanical shock?+
Synchronics performs full mechanical assessment of overpressure-damaged WIKA Bourdon tubes using pressure cycling and pointer response testing. If the tube metal is permanently deformed or cracked, we recommend replacement of the tube assembly (more economical than full gauge replacement). For repairable gauges, we perform internal cleaning, pointer re-zeroing, and full pressure cycle testing from 0 to 150% of range to ensure mechanical integrity. All work is documented with before-and-after calibration certificates.
How do I send my WIKA 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 WIKA 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 WIKA 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 WIKA 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.
