INDUSTRIAL SENSORS Product Lines We Repair
Our engineers are trained on the full INDUSTRIAL SENSORS product range. Below are the major product families we service.
Inductive Proximity Sensors
Inductive proximity sensors detect ferrous metals without physical contact. Common failures include coil burnout from voltage spikes, corrosion of the sensing face in wet environments, and loss of switching distance due to mounting distance drift. Synchronics replaces damaged coil assemblies and recalibrates sensor sensitivity.
Photoelectric Sensors
Diffuse-reflection and retroreflective photoelectric sensors are used in packaging, material handling, and conveyor systems. Faults include LED degradation causing reduced sensing range, lens contamination from dust and oils, and receiver amplifier drift over time. Synchronics cleans optical paths, replaces LED assemblies, and recalibrates gain settings.
Pressure and Temperature Transmitters
4-20 mA analog transmitters convert pressure and temperature into standardized signals for DCS and PLC integration. Failures include zero and span drift due to aging electronic components, connector corrosion in humid environments, and diaphragm rupture under overpressure. Synchronics recalibrates transmitters to within 0.5% accuracy and replaces corroded connectors.
Ultrasonic Distance Sensors
Ultrasonic sensors measure distance by emitting sound pulses and detecting reflections. Faults include transducer crystals cracking under thermal shock, moisture ingress into the piezo element, and noise immunity loss in high-vibration environments. Synchronics replaces piezo assemblies and improves shielding.
Sensor Interface Modules and Amplifiers
Amplifier modules and IO-Link masters convert sensor signals for PLC integration. Faults include capacitor failure causing output noise, voltage regulator thermal shutdown, and digital communication timeouts. Synchronics diagnoses firmware issues, replaces power supply modules, and restores communication with PLC networks.
Capacitive Level and Proximity Sensors
Capacitive sensors detect both conductive and non-conductive materials by measuring capacitance change. Common faults include false triggers from humidity changes, ground plane sensitivity requiring recalibration, and electrode surface corrosion in chemical environments. Synchronics adjusts sensitivity thresholds and replaces corroded sensor tips.

Common INDUSTRIAL SENSORS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INDUSTRIAL SENSORS equipment arriving at our workshop.
- ✓Inductive sensor coil open circuit failure — Electrical overvoltage spikes from nearby contactors or PLC power supply transients damage the sensor coil windings. This is especially common in Indian textile mills and automotive foundries with poor power quality and inadequate surge suppression. Over time, the wire insulation degrades and breaks.
- ✓Photoelectric sensor reduced sensing range or complete darkness — LED light output decays naturally over 50,000+ operating hours. Oil mist, dust, or condensation deposits on the optical lens reduce light transmission. In Indian food processing plants, turmeric powder or flour dust commonly blocks sensors within months if not sealed properly.
- ✓Pressure transmitter zero and span drift outside 1% accuracy — Aging of the piezoresistive element and analog conditioning circuits causes signal shift. Temperature fluctuations in outdoor installations or steam-heavy environments (common in Indian chemical and pharmaceutical plants) accelerate drift. Capacitor leakage in the signal conditioning board introduces offset errors.
- ✓IO-Link communication timeout or CRC checksum error — Noise coupling on sensor signal wires occurs when cables run parallel to motor power cables or welding equipment. Loose M12 connectors corrode in humid environments, introducing intermittent contact. IO-Link firmware version mismatch between sensor and master module causes handshake failures.
- ✓Capacitive sensor false triggers or inability to detect target material — High ambient humidity causes capacitive coupling with sensor electrodes, generating false alarms. In sugar mills, flour factories, and pharma plants, dielectric material buildup on sensor electrodes changes the capacitance baseline. Proximity to metal or earthed structures shifts the sensor's electrical field.
- ✓Temperature transmitter erratic readings or -20°C lockup — RTD sensor lead resistance changes with temperature, causing measurement errors if transmitter does not use 3-wire or 4-wire configuration. In Indian textile plants with high vibration, RTD wires fracture inside the thermowell. Cold-junction compensation circuit failure causes absolute temperature offset errors.

Frequently Asked Questions — INDUSTRIAL SENSORS Repairs
Do you repair Industrial Sensors equipment at your facility in Vadodara?+
Yes. Synchronics has a full-service repair facility in Vadodara, Gujarat equipped with precision test benches, calibration standards, and replacement component inventory for all Industrial Sensors products. We accept shipments from every Indian state and return repaired sensors with calibration certificates within 5-7 working days. Express turnaround available for critical plant shutdowns.
Can you recalibrate Industrial Sensors transmitters to NABL standards?+
Yes. Our facility maintains NABL-traceable pressure and temperature calibration standards. We recalibrate Industrial Sensors 4-20 mA transmitters, PT100 temperature sensors, and pressure transducers to 0.1% to 0.5% accuracy depending on the transmitter class. You receive calibration certificates showing before/after readings and measurement uncertainty for regulatory compliance (ISO 9001, ISMS, API compliance).
How do I diagnose if my inductive proximity sensor is failing?+
Use a multimeter to check for DC supply voltage (typically +10V to +30V) at the sensor connector. If voltage is present, use an oscilloscope to verify switching output pulse when a ferrous object approaches. Loss of output pulse with correct supply voltage indicates internal coil failure. Synchronics can test the sensor coil with a megohmmeter and replace the entire head within 24 hours if needed. Send photos of your sensor model and connection diagram.
What is the typical lifespan of Industrial Sensors photoelectric LED elements?+
Industrial Sensors photoelectric sensors typically operate 50,000-100,000 hours before LED light output degrades below minimum detection range (usually a 30-50% loss). In Indian food processing and textile plants with continuous 24/7 operation, this translates to 5-8 years. Synchronics recommends preventive LED replacement every 3-4 years in critical automation lines to avoid unexpected downtime. We stock replacement LED modules and can schedule planned maintenance around production schedules.
My Industrial Sensors pressure transmitter reads -0.5 bar in open air; how do I fix the zero offset?+
This indicates a zero drift of approximately 0.5 bar, likely caused by aging of the electronic zero potentiometer or capacitor leakage. Do not attempt field adjustments as this can worsen accuracy. Ship the transmitter to Synchronics with documentation of the error. We perform a full recalibration, replace the output amplifier board if needed, and return it within 5 days with a NABL calibration certificate proving zero adjustment to within +/- 0.05 bar.
How do I send my INDUSTRIAL SENSORS 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 INDUSTRIAL SENSORS 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 INDUSTRIAL SENSORS 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 INDUSTRIAL SENSORS 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.
