SDT Equipment We Repair — By Category
SDT Product Lines We Repair
Our engineers are trained on the full SDT product range. Below are the major product families we service.
Ultrasound Pro
Portable ultrasonic measurement system for condition monitoring, mechanical diagnostics, and air leak detection. Common issues include transducer sensor drift, measurement calibration loss, and LCD display panel faults.
Bearing Condition Monitor (BCM)
Fixed-installation bearing health monitoring system with dual-channel ultrasonic and acceleration sensors. Typical failures include sensor disconnection, relay module failure, and data logging SD card corruption.
Airborne Ultrasound (AUC)
Handheld airborne ultrasonic detection for corona discharge, steam trap function testing, and partial discharge inspection. Common faults include microphone capsule degradation and frequency filter blockage.
SDT270 Data Gateway
Industrial IoT interface for wireless sensor networks and condition data aggregation. Repair challenges include WiFi/4G modem failure, Ethernet port corrosion, and firmware corruption.
Vibration Meter
Handheld vibration and temperature measurement device for ISO 20816 compliance monitoring. Issues include accelerometer sensitivity loss, temperature probe open circuit, and display backlight failure.

Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 SDT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SDT equipment arriving at our workshop.
- ✓Ultrasonic transducer sensitivity loss or no signal — SDT ultrasonic sensors (typically 40 kHz piezo elements) degrade from moisture ingress, thermal cycling in outdoor substations, or mechanical shock. Indian humidity and monsoon exposure accelerates sensor failure.
- ✓BCM relay module failure - no alarm output — Bearing Condition Monitor relay banks fail from contact pitting caused by industrial noise interference, unfiltered DC power supplies, or moisture in control panels common in Indian mills and power plants.
- ✓Measurement calibration drift or incorrect dB readings — SDT Ultrasound Pro units lose calibration due to component ageing, temperature extremes in Indian climates, or incorrect sensor replacement with non-matched piezo elements.
- ✓SDT270 Gateway WiFi/4G connection loss or data drop — Cellular modem failure from power transients, antenna port corrosion in humid industrial environments, or firmware version mismatch in Indian cellular bands (B1, B3, B7, B8, B20).
- ✓LCD display flickering, dim, or complete black screen — Ultrasound Pro display panel degradation from heat exposure in outdoor monitoring applications, backlight LED failure, or LCD controller IC damage from electrical transients.
- ✓Airborne ultrasonic microphone capsule dead or very low signal — AUC2 probe microphone capsules degrade from dust accumulation in foundries and cement plants, chemical vapour exposure, or mechanical damage from field handling and dropped instruments.

Frequently Asked Questions — SDT Repairs
Do you repair SDT equipment anywhere in India?+
Yes. Synchronics repairs the full SDT ultrasonic and condition monitoring product range - Ultrasound Pro, Bearing Condition Monitors, Airborne Ultrasound detectors, SDT270 gateways, and vibration meters. We offer PAN India door-to-door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and 100+ other cities. All repairs are carried out in our certified facility in Vadodara, Gujarat, with turnaround times of 5-7 working days for most units.
What is the typical lead time for SDT ultrasonic sensor replacement?+
SDT transducer and microphone sensor replacements usually take 3-4 days including parts procurement, installation, and factory calibration testing. Synchronics stocks common SDT 40 kHz and 100 kHz sensor elements. For specialist frequencies or custom configurations, we coordinate directly with SDT UK to source exact OEM components. Emergency same-day sensor swaps are available for critical power utility and petrochemical monitoring systems at premium rates.
Can Synchronics repair SDT equipment without original documentation?+
Absolutely. Our engineers have extensive technical reference libraries for SDT Ultrasound Pro, BCM, AUC, and SDT270 product lines. We perform visual inspection, circuit-level diagnostics, and functional testing to identify faults even without user manuals. We then source schematic diagrams and service bulletins from SDT technical archives or reverse-engineer repair procedures for legacy equipment. A detailed service report is provided with all diagnostics and component replacements.
Do you offer calibration certificates for repaired SDT ultrasonic units?+
Yes. All SDT Ultrasound Pro and VMS vibration meters repaired by Synchronics receive calibration verification against factory reference standards and ISO 9001 calibration certificates valid for 12 months. We use traceable test equipment and document calibration curves for 20 kHz, 40 kHz, 100 kHz, and ultrasonic frequency bands. Certificates include sensor sensitivity, measurement accuracy, and date of recalibration, essential for quality audits in pharma, aerospace, and automotive supply chains.
What is the warranty on SDT equipment repaired by Synchronics?+
All SDT repairs carry a 12-month comprehensive warranty on replaced components and repaired circuits, covering parts and labour. This applies to sensor replacements, relay modules, LCD displays, modem cards, and calibration work. Warranty covers manufacturing defects and component failure - not accidental damage or misuse. We also offer extended warranty packages and preventive maintenance contracts for plants operating critical condition monitoring networks.
How do I send my SDT 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 SDT 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 SDT 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 SDT 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.
