OHMART Product Lines We Repair
Our engineers are trained on the full OHMART product range. Below are the major product families we service.
OHMART Capacitive Level Transmitters
Continuous level measurement transmitters using capacitive technology for liquids and slurries in tanks and vessels. Common repair issues include electrode fouling, insulation degradation, signal drift, and 4-20 mA output failure due to process chemical exposure.
OHMART Radar Level Sensors
Guided wave and free-space radar sensors for non-contact level detection in high-temperature, high-pressure, and corrosive environments. Typical faults include antenna fouling, microprocessor malfunction, and loss of RF signal due to cable damage or connector corrosion.
OHMART Proximity and Limit Switches
Inductive and capacitive proximity sensors for tank overflow, sump level, and process start-stop automation. Repair commonly involves sensor coil testing, connector replacement, and threshold calibration adjustment.
OHMART Signal Conditioning Electronics
Transmitter electronics, converter modules, and interface cards that convert sensor output to industrial protocols (4-20 mA, Hart, Modbus, RS-485). Faults include PCB corrosion, power supply failure, and communication module degradation.
OHMART Control and Display Units
Local display panels and control interfaces for real-time level monitoring and alarm indication. Common failures include LCD screen degradation, button contact wear, relay malfunction, and alarm setpoint drift.
OHMART Calibration and Test Kits
Field calibration equipment and reference standards used by maintenance teams to verify sensor accuracy. Repair includes potentiometer restoration, reference electrode refurbishment, and precision retuning.

Common OHMART Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in OHMART equipment arriving at our workshop.
- ✓Capacitive probe electrode fouling and coating buildup — Accumulation of process residue, mineral deposits, or scale on OHMART sensor electrodes causes capacitance shift and false level readings. Common in water treatment, chemical dosing, and wastewater applications across Indian municipal and industrial plants.
- ✓4-20 mA output loop not responding or stuck at 3.8 mA — OHMART transmitter electronics suffer from power supply filtering capacitor degradation, analog output stage failure, or Hart modem malfunction. Often triggered by electrical surges, inadequate loop power, or connector corrosion in humid or saline industrial environments.
- ✓Radar antenna ice buildup or signal attenuation loss — OHMART guided-wave and free-space radar sensors in cold-chain applications (dairy, food processing, chemical plants) accumulate ice or condensation on antenna surfaces, reducing RF signal transmission and causing wildly fluctuating measurements.
- ✓LCD display fading or segment dropout on OHMART CDU panels — Backlighting degradation, LCD controller IC aging, or intermittent PCB solder joint fractures cause partial or complete display failure. Prolonged exposure to heat in boiler rooms, furnace control areas, and solar thermal installations accelerates LCD failure in OHMART display units.
- ✓Sensor threshold setpoint drifting or alarm not triggering at calibrated level — OHMART proximity sensors and limit switches experience potentiometer wiper wear, capacitive coupling changes due to cable routing shifts, or analog comparator offset drift from component aging. This is critical in overflow prevention and sump pump control applications.
- ✓Intermittent RS-485 or Modbus communication loss on networked OHMART transmitters — EMI from variable frequency drives (VFDs), poor shielding on twisted pair cables, or degraded OHMART communication module ICs cause frame errors and timeouts on industrial automation networks. Particularly common in multi-transmitter installations across Indian sugar mills, refineries, and cement plants.

Frequently Asked Questions — OHMART Repairs
Do you repair OHMART equipment anywhere in India?+
Yes. Synchronics repairs the full OHMART product range — capacitive and radar level sensors, proximity switches, signal conditioning electronics, and display panels. We offer PAN India door-to-door courier pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, and all major industrial cities. Our main repair facility is in Vadodara, Gujarat, with turnaround times of 5-10 working days for most OHMART faults.
Can Synchronics repair OHMART capacitive sensors with chemical corrosion or electrode pitting?+
Absolutely. We have specialized electrode refurbishment capability. Our engineers perform optical inspection of OHMART probe tips, perform chemical passivation treatments, restore electrode surface finish using precision polishing, and recalibrate against reference standards. If electrodes cannot be salvaged, we source OEM or equivalent replacement probes. Most corroded OHMART sensors are restored to 95%+ of original accuracy.
What is the typical cost and lead time for OHMART transmitter electronics repair?+
OHMART signal conditioning and Hart/Modbus electronics repair typically costs INR 8,000 to 18,000 depending on fault complexity and component replacement needs. Diagnostics are free; we provide a quotation before proceeding. Standard turnaround is 7-10 working days. Rush service (3-5 days) is available on request. We offer 12-month warranty on all repaired OHMART transmitters.
Do you calibrate OHMART level sensors to customer setpoints after repair?+
Yes. Synchronics includes factory recalibration as part of every OHMART sensor repair. Our technicians restore sensors to OHMART specification using certified reference standards and calibration rigs. If you require custom setpoint programming (e.g., for new tank geometry or process changes), we can adjust OHMART transmitter output curves and provide calibration certificates traceable to ISO standards.
Can you repair OHMART radar sensors that show 'Lost Signal' or 'Low Signal Strength' errors?+
Yes. Low radar signal is typically caused by antenna fouling, coaxial cable water ingress, degraded connectors, or RF amplifier failure inside the OHMART sensor head. Synchronics performs RF signal strength testing, antenna inspection, cable continuity checks, and replaces failed RF modules. We test repaired sensors using calibrated test vessels and dummy loads before return to ensure full signal recovery.
How do I send my OHMART 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 OHMART 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 OHMART 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 OHMART 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.
