KNICK Equipment We Repair — By Category
KNICK Product Lines We Repair
Our engineers are trained on the full KNICK product range. Below are the major product families we service.
POSIDYNE Pressure Transmitters
KNICK POSIDYNE range includes analog and digital pressure transmitters used in process control loops. Common faults include zero-span drift, 4-20mA output failures, and connector corrosion in humid environments typical of Indian chemical and pharma plants.
TRANSIDYNE Flow & Level Instruments
KNICK TRANSIDYNE instruments provide ultrasonic and electromagnetic flow measurement with integrated electronics. Repair common issues include sensor cable faults, amplifier failures, and display/output board degradation in high-vibration manufacturing environments.
DATADYNE Process Controllers
KNICK DATADYNE range includes compact controllers, data loggers, and multi-channel process monitoring units. Issues typically involve relay card failures, communication port faults (RS485, Modbus), and power supply problems under electrical surge conditions.
DIGISTAT Temperature & pH Controllers
KNICK DIGISTAT intelligent controllers for temperature, pH, and ORP measurement with analog/digital I/O. Common faults include sensor input amplifier drift, setpoint calibration loss, and display malfunctions after power surges or moisture ingress.
Signal Conditioning & Isolators
KNICK isolation amplifiers and signal converters used in multi-parameter process loops. Repair addresses galvanic isolation failures, frequency response degradation, and input/output impedance shifts common in noisy Indian manufacturing environments.
Why Choose Synchronics for KNICK Repairs?

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 KNICK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KNICK equipment arriving at our workshop.
- ✓4-20mA Output Loop Failure or Drift — KNICK transmitters (POSIDYNE, TRANSIDYNE) use precision D/A converters and output amplifiers that degrade due to thermal stress, power supply ripple, or connector corrosion. In Indian humid/coastal environments, oxidized connectors cause intermittent loop breaks or false readings.
- ✓Zero/Span Calibration Loss or Offset Error — KNICK process instruments store calibration coefficients in EEPROM or flash memory; power failures, firmware bugs, or sensor drift cause these values to corrupt or shift. This results in constant offset or non-linear response curves in field applications.
- ✓RS485/Modbus Communication Timeout or CRC Errors — KNICK DATADYNE controllers and networked instruments use RS485 differential signaling; cable impedance mismatches, EMI from adjacent VFDs/motors, or failed RS485 driver ICs cause communication dropouts or data corruption. Common in Indian plants with poor cable management.
- ✓No Display / LCD Segment Failure — KNICK controller and instrument displays (DATADYNE, DIGISTAT) use LCD/LED segments driven by multiplexed display drivers; component aging, solder cracks, or controller firmware lockups cause partial or total display loss, making unit unusable despite functioning sensors.
- ✓Sensor Input Amplifier Offset or Gain Error — KNICK analog front-end circuits (input amplifiers for pressure, temperature, pH sensors) suffer from precision resistor/capacitor drift, op-amp aging, or bias current leakage. High ambient temperatures in Indian pharma/chemical plants accelerate this degradation.
- ✓Power Supply Failure (No Output or Intermittent Shutdown) — KNICK instruments use linear or switch-mode power supplies; electrolytic capacitors dry out or fail due to heat/age, rectifier diodes short, or pass-transistors fail under load surges. Inadequate power conditioning in Indian industrial environments (voltage spikes) accelerates failures.

Frequently Asked Questions — KNICK Repairs
Do you repair KNICK instruments anywhere in India?+
Yes, Synchronics repairs the complete KNICK product portfolio across India. We offer pan-India pickup and delivery from Delhi, Mumbai, Pune, Hyderabad, Chennai, Ahmedabad, Bangalore, and all tier-2 cities. All repairs are handled at our ISO-certified facility in Vadodara, Gujarat, with typical turnaround of 7-10 working days. Same-day courier delivery available for express repairs.
What is your typical turnaround time for KNICK transmitter and controller repairs?+
Standard turnaround is 7-10 working days from receipt, including diagnostics, component replacement, recalibration, and testing. For critical pharma and food processing clients, we offer express turnaround of 3-4 days with additional charges. Emergency on-site repairs and calibration are also available in Vadodara and nearby regions.
Can you recalibrate KNICK POSIDYNE and TRANSIDYNE instruments to ISO/pharma standards?+
Absolutely. Synchronics performs full recalibration of KNICK transmitters and instruments using NIST-traceable reference standards. We generate calibration certificates with 3-point, 5-point, or full-range linearity reports suitable for pharma GMP audits and ISO quality systems. We also document zero/span drift before and after repair, providing regulatory compliance evidence.
Do you stock genuine KNICK spare parts or use alternatives?+
We use genuine KNICK components, KNICK-specified equivalents, and tested alternatives only when original parts are unavailable or obsolete. For long-obsolete KNICK instruments, we source equivalent precision resistors, capacitors, op-amps, and display modules from authorized suppliers. All replacements are validated against original specifications. We always inform clients before using non-original parts.
What if my KNICK instrument is not in your catalog — will you still repair it?+
Yes. While we maintain expertise on POSIDYNE, TRANSIDYNE, DATADYNE, and DIGISTAT ranges, Synchronics repairs all KNICK signal conditioning, process control, and measurement products. Simply send us the model number, and we will assess repair feasibility. KNICK documentation and schematics are available through our technical team, allowing us to service even older or rare instruments.
How do I send my KNICK 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 KNICK 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 KNICK 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 KNICK 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.
