S+S Equipment We Repair — By Category
S+S Product Lines We Repair
Our engineers are trained on the full S+S product range. Below are the major product families we service.
S+S RTD and Thermocouple Transmitters
Temperature measurement transmitters with integrated signal conditioning for 4-20mA or 0-10V analogue outputs. Common faults include sensor input instability, output signal drift, and temperature offset errors in harsh industrial environments.
S+S Pressure and Differential Pressure Transducers
Precision pressure sensors with integrated electronics for process control and monitoring. Typical repair issues involve zero-point drift, non-linear output, electrical connector corrosion, and membrane rupture in high-vibration or corrosive applications.
S+S Multi-Parameter Process Transmitters
Integrated transmitters for simultaneous measurement of temperature, pressure, and humidity in critical applications. Failures commonly include CPU module faults, memory errors, calibration data loss, and communication protocol failures in networked installations.
S+S Signal Conditioners and I/O Modules
Standalone signal processing units for amplification, isolation, and linearisation of sensor signals. Repair typically addresses input stage failures, output amplifier saturation, isolation barrier breakdown, and calibration register corruption.
S+S Display and Control Units
Panel-mounted and portable display instruments for real-time process parameter indication and local control. Common failures include LCD/LED segment failures, button contact degradation, battery management circuit faults, and firmware boot errors.

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 S+S Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in S+S equipment arriving at our workshop.
- ✓RTD transmitter output signal drift and instability — Thermowell contamination, sensor wire insulation degradation in high-temperature applications, or input amplifier offset drift caused by thermal cycling in S+S RTD transmitters. Moisture ingress into terminal blocks also causes intermittent signal dropout.
- ✓Pressure transducer output clamped at maximum or minimum — Diaphragm rupture or internal sensing element damage in S+S pressure transmitters exposes electronics to process fluid ingress. Alternatively, output signal conditioning circuit failure causes hard clamping or loss of analogue signal within the 4-20mA loop.
- ✓Multi-parameter transmitter non-volatile memory corruption — Power supply surges, improper power-down sequencing, or flash memory wear-out in S+S MP-TX series cause loss of calibration coefficients, sensor type definitions, and output scaling parameters. Symptoms include wildly fluctuating readings or fixed null output after reboot.
- ✓Signal conditioner input stage saturation and noise injection — Transducer output impedance mismatch, electromagnetic interference from adjacent power cables, or damaged input coupling capacitors in S+S SC-1100/2100 series prevent proper signal acquisition and amplification, causing erratic output readings.
- ✓Transmitter local/remote communication protocol timeout or data corruption — Corrupted serial EEPROM, damaged RS-485 or HART communication driver IC, or firmware version incompatibility in networked S+S transmitters causes instrument to become invisible to process control systems or exchange garbled measurement data.
- ✓Display module LCD/LED segment failure and backlight loss — Thermal stress from process temperature fluctuations, mechanical vibration fatigue in LCD segment drivers, or backlight inverter failure in S+S DIS-P series causes partial or complete loss of visual indication on control panel instruments.

Frequently Asked Questions — S+S Repairs
Do you repair S+S equipment anywhere in India?+
Yes. Synchronics repairs the full S+S product range—temperature transmitters, pressure transducers, multi-parameter instruments, signal conditioners, and display units. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and all other metro and tier-2 cities. All repairs are conducted at our primary facility in Vadodara, Gujarat, with turnaround times of 5-10 working days for standard repairs.
How do you diagnose and repair S+S RTD and thermocouple transmitter faults?+
Our engineers perform systematic diagnostics starting with input sensor simulation, amplifier DC bias measurement, and output loop current verification. We use precision calibrators to inject known sensor signals and validate transmitter response across the full measurement range. We repair or replace failed input coupling stages, recalibrate trimmer networks, and perform thermal stability testing over extended temperature cycles to identify and eliminate drift-prone components before return.
What is your typical turnaround time for S+S pressure transducer repair in India?+
Standard pressure transducer repairs—output offset drift, signal conditioning failures, or terminal block replacement—are typically completed within 7-10 working days. Sensor element replacement (requiring recalibration and metrological verification) may extend turnaround to 10-14 days. We offer expedited repair (3-5 days) for critical plant shutdowns. All transducers are returned with full pressure testing and 4-20mA loop certification.
Can Synchronics recover lost calibration data from S+S multi-parameter transmitters?+
Yes, provided the transmitter's non-volatile memory is accessible and not physically destroyed. We extract and back up configuration files, diagnose memory corruption sources, and perform flash/EEPROM repair or replacement. Where customer calibration records are available, we restore original coefficients. In cases of permanent calibration loss, we recalibrate transmitters to S+S factory default settings or to your custom specifications if you provide historical sensor span and offset data.
What warranty do you provide on repaired S+S equipment?+
All S+S equipment repaired by Synchronics carries a 12-month parts and labour warranty covering manufacturing defects and workmanship failures. This excludes damage from physical abuse, overvoltage surges, or chemical exposure beyond original equipment specifications. We recommend preventive maintenance calibration annually for critical process measurement instruments to maintain accuracy and reliability in harsh Indian manufacturing environments.
How do I send my S+S 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 S+S 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 S+S 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 S+S 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.
