SETRA Equipment We Repair — By Category
SETRA Product Lines We Repair
Our engineers are trained on the full SETRA product range. Below are the major product families we service.
Model 206 - Compact Pressure Transducer
Miniature transducers for OEM integration and point-of-use pressure monitoring. Common faults include zero drift after thermal cycling, connector oxidation in humid environments, and signal loss due to internal seal degradation.
Model 209 - Industrial Pressure Transmitter
4-20mA and 0-10V output transmitters for HVAC balancing, cleanroom pressure control, and process monitoring. Typical failures: 4mA offset errors, intermittent 20mA saturation, and I2P (current-to-pressure) linearisation drift.
Model 3100 - Differential Pressure Transducer
High-accuracy DP sensors for filter monitoring, ductwork balance, and cleanroom integrity verification. Repair focus: diaphragm rupture from overpressure, zero calibration loss, and hysteresis errors after age.
Model 1100 - Temperature Transmitter
RTD and thermocouple-based temperature signal conditioning with 4-20mA output. Common issues: cold-junction reference drift, RTD excitation circuit failure, and linearisation errors in extreme process temperatures.
Model 270 - Air Velocity Sensor
Hot-wire anemometer sensors for HVAC commissioning and ductwork diagnostics. Typical faults: sensor contamination from particulate buildup, amplifier gain loss, and temperature compensation module failure.
Environmental Monitoring Controllers
Multi-input controllers for pharmaceutical cleanrooms and food processing facilities with data logging and alarm relay outputs. Failures include relay chatter, LCD/LED display failure, and memory card data corruption.

Common SETRA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SETRA equipment arriving at our workshop.
- ✓Zero calibration drift in Setra transducers — Long-term exposure to moisture ingress through connector seals, combined with thermal cycling in Indian summer heat (40-45°C ambient). Dielectric grease degradation inside connectors allows water vapor to reach silicon sensing elements.
- ✓4-20mA output stuck at 4mA or non-responsive — Setra Model 209 and 3100 transmitters fail due to precision op-amp degradation in the current-output driver stage, especially in PCBs exposed to thermal stress. Solder joint micro-cracks in the feedback resistor network also cause fixed output levels.
- ✓Intermittent signal loss or dropout in DP transducers — Setra Model 3100 differential pressure sensors fail intermittently when diaphragm flex causes internal bridge-circuit open connections. Vibration from HVAC fans or process equipment aggravates mechanical stress on solder joints connecting the sensing element to the signal conditioning PCB.
- ✓Non-linear output or span error after environmental storage — Setra transducers stored in uncontrolled Indian warehouses (especially coastal areas) experience salt-spray corrosion on connector pins and hysteresis in the sensing diaphragm material. Span typically shifts 2-5% from original calibration.
- ✓RTD or thermocouple transmitter temperature offset error — Setra Model 1100 temperature transmitters exhibit temperature measurement offset when the cold-junction reference IC drifts due to aging or when RTD excitation current changes due to voltage regulator failure. Common in pharmaceutical cold rooms and cleanrooms where stable ±0.5°C accuracy is critical.

Frequently Asked Questions — SETRA Repairs
Do you repair Setra equipment anywhere in India?+
Yes. Synchronics repairs the full Setra transducer, transmitter, and sensor portfolio across India. We operate from our facility in Vadodara, Gujarat, and offer PAN-India door pickup from major cities — Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and Kolkata. Express courier to Vadodara takes 1-3 days; repair turnaround is typically 4-7 working days depending on fault complexity.
Can Synchronics calibrate Setra transducers post-repair?+
Absolutely. We perform full NIST-traceable calibration on all Setra pressure, differential pressure, and temperature transmitters after repair. Calibration is performed on precision pressure benches and RTD dry-block temperature calibrators. Each unit receives a calibration certificate with uncertainty bands, ideal for pharmaceutical, food, and regulated facilities requiring compliance documentation.
What is the typical lead time for Setra transducer repair in India?+
Standard turnaround is 4-7 working days from receipt at Synchronics Vadodara. Urgent repairs (diagnostic-only or connector replacement) can be completed in 2-3 days. We provide daily repair status updates via email. International spare parts for Setra are sourced from US suppliers, so complete sensor element replacement may require additional 5-7 days for parts procurement. Rush procurement is available for critical plant downtime scenarios.
How do I know if my Setra Model 206 or 209 transmitter is faulty?+
Common signs: output reading differs from reference gauge by >2%, erratic 4-20mA signal fluctuations, complete loss of output, or visible corrosion on connector pins. For diagnostic confirmation, Synchronics performs bench testing using precision pressure generators and loop simulators. If your Setra sensor is suspect, contact us with photos of the connector condition and we can advise if on-site recalibration or factory repair is needed.
Do you stock Setra replacement parts (diaphragms, connectors, circuit boards)?+
We maintain stock of common Setra connector types, dielectric sealing compounds, and high-reliability op-amp ICs used in Model 1100 and 209 transmitters. Complete diaphragm assemblies and custom PCBs are sourced from authorised US Setra distributors on a case-by-case basis. For critical spares, we recommend contacting Setra's Indian distributor or Synchronics' procurement team to arrange expedited import if lead times are urgent.
How do I send my SETRA 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 SETRA 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 SETRA 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 SETRA 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.
