CROMPTON INSTRUMENTS Product Lines We Repair
Our engineers are trained on the full CROMPTON INSTRUMENTS product range. Below are the major product families we service.
Analog Panel Meters
Crompton's classic moving-coil meters for AC/DC voltage, current, and power measurement. Common issues include pointer stiction, worn bearings, coil drift, and magnet weakening affecting zero calibration and measurement accuracy.
Digital Panel Meters
Crompton digital displays for voltage, current, temperature, and frequency monitoring. Failures include LCD segment loss, internal relay sticking, analog-to-digital converter errors, and 4-20 mA input circuit faults affecting process control loops.
Temperature Controllers and Indicators
Crompton thermostat and RTD-based temperature measurement devices used in furnaces, boilers, and reactors. Typical faults include thermocouple input circuit failure, relay contact welding, setpoint drift, and display failure.
Load Cells and Weighing Transducers
Crompton strain-gauge load measurement systems for batching, quality control, and safety-critical weighing. Common repairs involve amplifier PCB failure, excitation voltage dropout, signal conditioning errors, and mechanical seal degradation.
Pressure and Flow Instruments
Bourdon tube and diaphragm-based pressure gauges with electrical contacts, plus flow switches. Failures include pointer freezing, snubber valve blockage, electrical contact corrosion, and gauge tube rupture.
Switchboard and Distribution Panel Instruments
Crompton multi-range meters and selector switch assemblies for electrical distribution boards in power plants and substations. Issues include selector contact wear, meter burn-out from overrange, and mechanical linkage wear.

Common CROMPTON INSTRUMENTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CROMPTON INSTRUMENTS equipment arriving at our workshop.
- ✓Analog pointer stuck or sluggish response — Crompton moving-coil meters suffer bearing wear, dirt accumulation, or magnet weakening over decades of operation in dusty Indian plant environments. Pointer friction increases, reducing measurement responsiveness.
- ✓Digital display segments missing or faint — LCD segment failure in Crompton digital meters results from moisture ingress, solder joint fracture under thermal cycling, or backlight LED dimming. Affects readability on panel-mounted units in high-humidity environments.
- ✓Temperature controller not responding to setpoint changes — Crompton thermostat input amplifier or ADC failure prevents setpoint detection in TC-100 series controllers. Relay control circuit may also fail, preventing heater/cooler command output.
- ✓Load cell zero drift or non-linearity in weight readings — Crompton strain-gauge cells develop zero shift due to cable insulation breakdown, amplifier offset drift, or mechanical seal leakage affecting internal moisture. Linearity error grows when excitation voltage sags.
- ✓Pressure gauge pointer pegged or unresponsive — Bourdon tube rupture, snubber valve obstruction from mineral deposits, or internal linkage breakage immobilizes Crompton gauge pointers. Common in high-vibration environments like thermal power stations and paper mills.
- ✓Switchboard selector switch contacts corroded or non-conductive — Crompton distribution panel selector contacts suffer corrosion and pitting from moisture and electrical arcing in high-current industrial environments. Contact resistance rises, causing meter burn-out or no-reading fault.

Frequently Asked Questions — CROMPTON INSTRUMENTS Repairs
Do you repair Crompton Instruments equipment anywhere in India?+
Yes. Synchronics repairs the full Crompton Instruments product range — analog meters, digital panel meters, temperature controllers, load cells, pressure instruments, and switchboard assemblies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are performed at our central facility in Vadodara, Gujarat, with 180+ engineers and comprehensive calibration labs.
Can Crompton analog meters be recalibrated to meet Indian power utility standards?+
Absolutely. Crompton analog meters used in Indian power plants and substations must meet IS 1248 (panel meter accuracy class 1.0 or 2.0). Synchronics performs full-range recalibration using calibrated decade boxes and traceable standards, adjusting zero and span potentiometers per Crompton service manuals. We issue calibration certificates valid for regulatory and maintenance audits.
What is the typical turnaround time for Crompton temperature controller repair?+
Most Crompton TC-100 and TI series temperature controller repairs are completed within 5-7 working days. Simple repairs like RTD input stage replacement take 2-3 days. Complex failures (PCB replacement, full recalibration) may take 7-10 days. We provide real-time status updates and offer express repair service for critical furnace or reactor controls affecting production schedules in Indian chemical and pharmaceutical plants.
Do you stock replacement parts for Crompton Instruments meters?+
Yes. Synchronics maintains inventory of common Crompton replacement modules including analog meter movements, digital display modules, relay cards, thermocouple input stages, and load cell amplifiers. We also source genuine Crompton spare parts from authorized distributors when required. For obsolete Crompton models, we design equivalent functional replacements using modern components, maintaining original panel cutout dimensions and electrical compatibility.
Can Crompton pressure gauge or load cell repairs be done on-site at Indian manufacturing plants?+
Field repair of Crompton pressure gauges and load cells is possible for certain issues—contact cleaning, seal replacement, or simple linkage adjustment. However, full recalibration and testing require laboratory equipment. Synchronics collects equipment on-site, performs repairs and calibration at our Vadodara facility, and returns it within 10-14 days. For critical applications, we offer spare instrument exchange to minimize plant downtime.
How do I send my CROMPTON 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 CROMPTON 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 CROMPTON 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.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your CROMPTON INSTRUMENTS 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.
