DORIC Product Lines We Repair
Our engineers are trained on the full DORIC product range. Below are the major product families we service.
DORIC Thermocouple Transmitters
Precision temperature measurement devices converting thermocouple signals to 4-20mA or digital outputs. Common issues include cold junction compensation drift, connector corrosion in humid environments, and signal noise from electromagnetic interference in industrial settings.
DORIC Digital Process Indicators
Single and multi-channel LCD display units for temperature, pressure, and process variable monitoring. Failures typically involve display segment degradation, membrane keypad intermittency, and power supply failures in harsh plant environments.
DORIC Signal Conditioning Modules
Modular 4-slot or 6-slot rack systems for integrating multiple input/output channels. Common faults include input isolation failure, output amplifier saturation, and calibration drift requiring recalibration against known standards.
DORIC Platinum RTD Converters
High-precision resistance temperature detector (RTD) signal conditioning for Pt100 and Pt1000 sensors. Issues arise from bridge circuit imbalance, reference voltage instability, and sensor excitation current mismatches in temperature-critical applications.
DORIC Data Logging & Recording Systems
Chart recorder and digital data storage units for continuous process documentation and compliance recording. Repairs address paper feed mechanism jams, pen servo failures, and solid-state storage interface problems in validation-critical environments.
DORIC Calibration Standards & References
Precision reference voltage and temperature simulators for instrument calibration and verification. Maintenance involves restabilizing Zener reference circuits, recalibrating resistor networks, and replacing aging precision components.

Common DORIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DORIC equipment arriving at our workshop.
- ✓Thermocouple signal noise and erratic readings — DORIC transmitters operate on millivolt-level thermocouple signals extremely susceptible to electromagnetic interference from nearby power cables, VFDs, and switching equipment common in Indian manufacturing plants. Poor shielding, improper grounding, or corroded connector pins amplify noise.
- ✓Cold junction compensation drift causing temperature offset — DORIC thermocouple transmitters use internal reference junctions to compensate for ambient temperature variations. Over time, thermistor aging, capacitor drift, and solder joint degradation cause calibration errors ranging from 1-5 degrees Celsius, critical in pharmaceutical and food processing.
- ✓4-20mA output stuck at minimum or maximum value — DORIC transmitter output amplifiers fail from thermal stress, component aging, or power supply instability. Output transistors may saturate (full 20mA) or become open-circuit (minimum 4mA), preventing normal process control loop operation.
- ✓LCD display segments missing or fading — DORIC digital indicators use LCD technology susceptible to segment failure from long operating hours, thermal cycling in uncontrolled Indian plant environments, and manufacturing defects. Partial segment loss makes readings ambiguous and unreliable.
- ✓Power supply failure or voltage regulation instability — DORIC instruments operating in Indian industrial environments face voltage fluctuations, poor grounding, and contamination from dust and humidity. Electrolytic capacitors age prematurely, bridge rectifiers fail, and linear regulators drift, causing erratic instrument behavior or complete shutdown.
- ✓Calibration loss or nonlinear signal response — DORIC transmitters store calibration data in nonvolatile memory or analog potentiometers prone to drift. Factory calibration constants may be lost from power cycling, electrostatic discharge, or component aging, causing systematic measurement errors across the full signal range.

All repairs are completed at our Vadodara, Gujarat facility with turnaround typically 5-7 working days.
What is typical turnaround time for DORIC thermocouple transmitter repair?+
Standard DORIC transmitter repairs including connector cleaning, cold junction compensation recalibration, and output stage testing take 3-5 working days. Urgent cases with component replacement can often be expedited within 48 hours. We provide temporary loaner equipment if available to minimize your plant downtime during critical measurement operations.
Can you recalibrate DORIC instruments to factory specifications?+
Absolutely. Synchronics maintains NIST-traceable reference standards and performs complete recalibration of DORIC transmitters, indicators, and signal conditioning modules. We document all calibration points, provide certificates of calibration meeting ISO 17025 requirements, and are fully compliant with pharma and food industry validation standards required across Indian manufacturing sectors.
Do you stock spare parts for DORIC equipment?+
Yes. Synchronics maintains inventory of common DORIC replacement components including thermistors, amplifier ICs, output transistors, connector assemblies, and LCD displays. For obsolete DORIC parts no longer in production, our engineers identify equivalent modern components that meet or exceed original specifications and validate them through rigorous testing before installation.
What documentation do I need to provide when sending DORIC equipment for repair?+
Please provide the DORIC model number, serial number, fault description, and expected input/output range or thermocouple type (J, K, T, E, R, S). If available, include original calibration certificates and maintenance history. Our technical team will inspect the equipment and contact you with repair assessment and quotation within 24 hours of receipt in Vadodara.
