RISHABH INSTRUMENTS Equipment We Repair — By Category
RISHABH INSTRUMENTS Product Lines We Repair
Our engineers are trained on the full RISHABH INSTRUMENTS product range. Below are the major product families we service.
RPC Series - Process Controllers
Microprocessor-based process controllers for temperature, pressure, and flow control. Common issues include failed analog input cards, relay output card failures, and firmware corruption in multi-loop applications.
RTT Series - Temperature Transmitters
4-20mA and digital output temperature transmitters with RTD/thermocouple inputs. Repair focus includes sensor calibration drift, signal conditioning circuit failures, and connector corrosion in humid environments.
RPS Series - Pressure Transmitters
0-10V and 4-20mA pressure transmitters for pneumatic and hydraulic lines. Common faults include diaphragm rupture, amplifier board failures, and zero/span drift requiring recalibration.
RLS Series - Level Switch Controllers
Programmable level control units with capacitive and float switch inputs. Typical repairs involve relay card replacement, input circuit failures, and false trigger calibration in chemical tanks.
RDM Series - Data Acquisition Modules
Multi-channel analog data logging and signal conditioning modules with Modbus interface. Failures include ADC conversion errors, memory chip corruption, and serial communication port failures.
RPS-SMART - IoT Enabled Sensors
WiFi and GSM-enabled industrial transmitters for remote monitoring. Repair challenges include wireless module failure, power management circuit issues, and firmware update recovery.

Common RISHABH INSTRUMENTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in RISHABH INSTRUMENTS equipment arriving at our workshop.
- ✓RPC Series analog input card failure — Rishabh analog input modules (16-bit ADC cards) suffer from capacitor aging and burst failures in high-humidity Indian factory environments. This causes erratic temperature or pressure readings and control instability.
- ✓RTT Series sensor calibration drift — Rishabh RTD and thermocouple transmitters drift over 18-24 months due to amplifier aging and reference voltage instability. Particularly common in pharmaceutical batch processes where accuracy is critical.
- ✓RLS Level controller relay card burnout — Rishabh RLS series relay output cards experience contact welding and coil failures when switching high-inrush loads in chemical dosing applications. Moisture ingress accelerates failure in coastal and humid regions.
- ✓RDM Modbus communication timeout — Rishabh RDM data acquisition modules fail to respond on Modbus network due to corrupted serial firmware or failed RS-485 driver IC. Common in automotive assembly plants with high EMI environments.
- ✓RPS-SMART wireless module connection loss — Rishabh IoT-enabled transmitters lose WiFi or 4G connectivity due to module firmware bugs, certificate expiry, or power supply ripple affecting the wireless chipset. Results in missing cloud data uploads.
- ✓RPC Series display panel dark or corrupted — Rishabh process controller LCD backlight failure and segment corruption occurs after 5-7 years of operation. Causes loss of setpoint visibility and emergency operation difficulty in food processing plants.

We offer pan-India door pickup and dispatch from our Vadodara facility. Same-day dispatch available for Delhi, Mumbai, Pune, and Ahmedabad. Full warranty on all repairs.
What is the turnaround time for Rishabh RPC Series process controller repair?+
Standard repair turnaround is 5-7 working days from receipt. Express service available for pharmaceutical customers — 48-72 hours with priority board-level diagnostics and component replacement. We test all repaired controllers for full stability under simulated process loads before release.
Can Synchronics recalibrate Rishabh temperature and pressure transmitters to NIST standards?+
Yes, absolutely. Synchronics maintains calibrated test benches for RTT and RPS series transmitters across 0-1000°C and 0-400 bar ranges. We provide NIST-traceable calibration certificates and adjust internal gain/offset for ±0.5% accuracy. Ideal for pharmaceutical batch records and ISO 9001 compliance.
What is your warranty on Rishabh Instruments repairs?+
We provide 12 months warranty on component-level repairs and 6 months on complete board replacements. Warranty covers same fault recurrence; excludes misuse, reverse polarity, or overvoltage damage. Extended 24-month warranty available for critical process equipment at additional cost.
Do you stock genuine Rishabh Instruments spare parts for emergency repairs?+
We stock high-demand Rishabh components including RTD/TC input cards, 4-20mA output modules, and relay cards. For obsolete or unavailable parts, we source directly from Rishabh within 48 hours. Custom firmware programming and EEPROM dumps available for legacy RPC series controllers manufactured before 2005.
How do I send my RISHABH INSTRUMENTS 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 RISHABH INSTRUMENTS 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 RISHABH INSTRUMENTS 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.
