Delta-mobrey Equipment We Repair — By Category
Delta-mobrey Product Lines We Repair
Our engineers are trained on the full Delta-mobrey product range. Below are the major product families we service.
Float Switch Assemblies
Mechanical and electronic float switches for on-off level control in tanks and vessels. Common issues include float arm sticking, mercury contact ball leakage, and electrical connector corrosion from chemical vapors and moisture ingress.
Capacitive Level Transmitters
Non-contact 4-20mA transmitters for continuous level measurement in conductive and non-conductive liquids. Failures include probe insulation breakdown, 4-20mA output drift, and false triggering from dielectric coating buildup.
Magnetic Level Gauges
Visual and transmitter-integrated magnetic level indicators for liquids in pressurized vessels and reactors. Typical faults include float magnet weakening, valve seat wear causing leakage, and scale glass fogging or cracking.
Relay Output Modules
Standalone and panel-mount relay units that accept 4-20mA inputs from Delta-Mobrey transmitters to trigger alarms or pump control. Relay chatter, contact burning, and hysteresis calibration drift are common service issues.
Smart Display and Converter Modules
Digital LCD indicators and 4-20mA/0-10V converter boxes for remote readout of Delta-Mobrey level data. Failures include LCD segment loss, ground loop hum in signal conversion, and power supply regulation faults.
Mounting and Isolation Valve Kits
Isolation block valves, snubbers, and differential pressure compensation kits used with Delta-Mobrey transmitters in high-vibration or pulsating fluid environments. Common issues include valve blockage from process fluid contamination and seal degradation.

Common Delta-mobrey Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in Delta-mobrey equipment arriving at our workshop.
- ✓Float switch mercury ball leakage or displacement — Mercury contact balls in older Delta-Mobrey float switches can separate from the float housing due to vibration, temperature cycling, or capsule seal failure. This breaks electrical continuity and causes the switch to fail in open state, halting level control logic.
- ✓Capacitive transmitter probe insulation degradation (low output or zero signal) — Delta-Mobrey capacitive probes exposed to harsh chemical fumes, high moisture, or caustic splash corrode the insulating resin coating. This reduces capacitance sensitivity and causes the transmitter to output erratic 4-20mA or remain stuck at 4mA.
- ✓Magnetic level gauge float magnet weakening or float sticking — Temperature excursions above 60°C, physical vibration impacts, or prolonged static pressure in tall columns can demagnetize or partially stick the internal float magnet in Delta-Mobrey gauge assemblies. This prevents visual indication and blocks magnetic switch actuation.
- ✓Relay output module contact chatter and hysteresis drift — Delta-Mobrey relay modules driven by noisy or fluctuating 4-20mA signals from transmitters cause relay contacts to chatter rapidly. Over time, contact erosion and spring fatigue increase hysteresis gap, causing delayed or missed alarm triggers.
- ✓LCD display segment loss or low contrast — Moisture ingress into Delta-Mobrey digital display units during rain or high-humidity warehouse storage causes LCD segment failure. Liquid crystal delamination or backlight aging reduces visibility, making level readings unreadable on the panel.
- ✓4-20mA signal converter ground loop hum and offset error — Delta-Mobrey converter modules installed in multi-wire industrial plants often experience ground loop hum when connected to AC-powered instruments or PLC analog inputs. This introduces 50Hz noise and DC offset errors, distorting transmitted level signals by 1-3%.

Frequently Asked Questions — Delta-mobrey Repairs
Do you repair Delta-Mobrey equipment anywhere in India?+
Yes. Synchronics repairs the full Delta-Mobrey product range — float switches, capacitive transmitters, magnetic level gauges, relay modules, and display converters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are performed at our certified facility in Vadodara, Gujarat, with calibration on site.
What is the typical turnaround time for Delta-Mobrey level transmitter repair?+
Standard Delta-Mobrey transmitter repairs (probe cleaning, insulation restoration, recalibration) take 3-5 working days. Urgent repairs with component replacement can be expedited to 24-48 hours. We offer express courier pickup for time-critical plant outages and provide loaner units if needed to minimize your production downtime.
Can you calibrate Delta-Mobrey capacitive and float switch level instruments to IS/ISO standards?+
Yes. Synchronics calibrates all Delta-Mobrey level instruments to ISO 9001, ISO/IEC 17025, and NATA traceable standards using precision liquid level baths, dead-weight testers, and calibrated 4-20mA signal sources. We issue detailed calibration certificates with uncertainty statements suitable for pharmaceutical, petrochemical, and food safety audits in India.
My Delta-Mobrey magnetic level gauge shows low contrast or phantom indications. Is it repairable?+
Yes. Low contrast or phantom (false) indications in Delta-Mobrey magnetic gauges are typically caused by float magnet weakening, guide rail binding, or internal reflection defects. Synchronics strips the gauge, re-magnetizes the float, cleans and lubricates the barrel, and replaces the reflective indicator tape if necessary. The majority of cases are restored to like-new performance.
Do you stock Delta-Mobrey spare parts or only repair faulty units?+
Synchronics repairs and restores Delta-Mobrey equipment as the primary service. For critical production spares, we maintain contact with authorized Delta-Mobrey distributors and can facilitate parts procurement on request. We also offer component-level replacements (float assemblies, mercury capsules, relay coils, LCD modules) as part of our repair service to restore equipment cost-effectively versus full replacement.
How do I send my Delta-mobrey 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 Delta-mobrey 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 Delta-mobrey 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 Delta-mobrey 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.
