ELECTRO-SENSORS Product Lines We Repair
Our engineers are trained on the full ELECTRO-SENSORS product range. Below are the major product families we service.
DFS Rotational Speed Sensors
Digital frequency sensors for real-time shaft speed monitoring in mills, pumps, and compressors. Common failures include bearing wear, optical lens contamination, and signal cable degradation affecting RPM accuracy.
MC Proximity Switch Systems
Mechanical and magnetic proximity switches for shaft position sensing and equipment lockout. Typical repairs involve magnet misalignment, contact degradation, and environmental contamination in harsh mill and foundry conditions.
CTS Cable-Tension Sensors
Specialized sensors for measuring cable and belt tension in conveyor systems and textile machinery. Failures commonly result from load cell drift, zero-calibration loss, and moisture ingress in humid environments.
EFS Encoder Feedback Systems
Modular encoder assemblies with integral signal conditioning for servo feedback and position control. Repair focus includes brush wear, commutator pitting, analog output linearity correction, and quadrature signal restoration.
TRH Temperature and Humidity Sensors
Environmental monitoring sensors integrated with speed detection for climate-sensitive process control. Common issues include capacitive drift, thermal compensation circuit failure, and condensation damage to sensor elements.

Common ELECTRO-SENSORS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELECTRO-SENSORS equipment arriving at our workshop.
- ✓DFS sensor output frequency dropout intermittent — Electro-Sensors rotational speed sensors suffer frequency signal loss when the optical window becomes contaminated with dust, oil mist, or metal particles common in Indian mills and foundries. Cable shield corrosion at the connector also causes intermittent signal dropout.
- ✓MC proximity switch magnet displacement or misalignment — Vibration from heavy machinery in textile mills and paper plants causes the permanent magnet in Electro-Sensors MC switches to shift from its calibrated position, reducing detection range and causing false triggers or failure to detect shaft rotation.
- ✓EFS encoder output linearity error or zero-offset drift — Brush wear and commutator pitting in Electro-Sensors EFS feedback encoders cause analog output voltage to deviate from linear position curve, resulting in servo position errors and closed-loop feedback instability in CNC machines and automation systems.
- ✓CTS cable-tension sensor reads false or fluctuating values — Load cell strain gauges in Electro-Sensors CTS sensors drift due to temperature changes, humidity-induced adhesive degradation, and mechanical hysteresis in the tension linkage—common in uncontrolled factory environments across Indian industries.
- ✓TRH environmental sensor capacitive reading unstable or unresponsive — Humidity condensation inside Electro-Sensors TRH sensor modules damages capacitive humidity sensing elements and temperature compensation circuitry. Potentiometer drift in the analog interface also causes reading instability.
- ✓Quadrature encoder signal phase error or pulse count mismatch — EFS encoder optical tracking errors or brush-commutator phase misalignment in Electro-Sensors systems cause A/B channel quadrature signals to become unbalanced, leading to position-count errors and stalled servo loops in precision machinery.

Frequently Asked Questions — ELECTRO-SENSORS Repairs
Do you repair Electro-Sensors equipment anywhere in India?+
Yes. Synchronics repairs the full Electro-Sensors product range - rotational speed sensors, proximity switches, encoder assemblies, cable-tension sensors, and environmental monitoring systems. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata and all other cities. Same facility in Vadodara, Gujarat with in-house calibration laboratory.
How do you ensure Electro-Sensors DFS sensor accuracy after repair?+
Synchronics performs multi-point frequency calibration against NIST-traceable frequency reference counters. We verify output signals across the entire operating RPM range, measure quadrature timing if applicable, and provide signed frequency accuracy certificates. Our bench testing simulates real shaft speeds to confirm sensor performance before return shipment.
Can you repair Electro-Sensors encoder assemblies with custom commutator specifications?+
Yes. We maintain a stock of standard Electro-Sensors EFS commutator blanks and can custom-machine diameters, groove patterns, and lead-lag specifications matching your original encoder. Synchronics tests each rebuilt encoder with precision commutator runout measurement and brush-to-commutator contact analysis.
What is the typical turnaround time for Electro-Sensors sensor repairs at Synchronics?+
Most Electro-Sensors repairs are completed within 7-10 working days from receipt - including diagnostics, component replacement, full calibration, and pressure-testing where required. Emergency same-day repairs available for critical plant operations across Indian manufacturing hubs with additional service charges.
Do you have spare parts in stock for Electro-Sensors TRH and CTS sensor modules?+
Synchronics maintains inventory of common replacement components for Electro-Sensors environmental sensors and cable-tension systems - capacitive humidity elements, strain gauge bridges, temperature compensation modules, and connector assemblies. Most repairs completed without extended parts lead time from USA.
How do I send my ELECTRO-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 ELECTRO-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 ELECTRO-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 ELECTRO-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.
