Common ARUN TECHNOLOGY A DIVISION OF SOLARTRON MOBREY LTD-ENGLAND Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARUN TECHNOLOGY A DIVISION OF SOLARTRON MOBREY LTD-ENGLAND equipment arriving at our workshop.
- ✓4-20mA output loss or erratic signal drift — Arun pressure and level transmitters often develop internal reference voltage decay or loose PCB connector contacts in high-vibration industrial environments, causing non-linear or zero output.
- ✓RTD bridge imbalance or thermistor calibration failure — Temperature compensation modules in Arun systems experience precision resistor drift and bridge circuit aging, particularly in thermal cycling environments common in Indian steel mills and heat-treatment plants.
- ✓Electrode coating or capacitive sensor failure — Arun level transmitters deployed in corrosive petrochemical and pharmaceutical environments accumulate mineral deposits, chemical film, and mechanical wear on capacitive electrodes, degrading measurement sensitivity and accuracy.
- ✓Frequency-to-current converter malfunction in flow systems — Arun flow measurement electronics experience failure in the magnetic pickup signal conditioning and frequency-to-4mA converter stage due to component aging, PCB board cracking, or input filter saturation in noisy plant environments.
- ✓Junction box seal failure and moisture ingress — Arun transmitter junction boxes exposed to monsoon humidity, wash-down environments, and thermal cycling in Indian manufacturing plants develop cracked seals and corroded internal connections.
- ✓Process controller communication module loss — Legacy Arun control modules experience parallel port or RS-232 communication failure due to electrostatic discharge in plants with poor grounding, static-prone environments, or incompatible industrial serial protocols.

Frequently Asked Questions — ARUN TECHNOLOGY A DIVISION OF SOLARTRON MOBREY LTD-ENGLAND Repairs
Do you repair Arun Technology and Solartron Mobrey instrumentation across India?+
Yes. Synchronics is authorised to repair the complete Arun Technology and Solartron Mobrey instrumentation range including pressure transmitters, level sensors, temperature modules, flow measurement systems, and process controllers. We offer PAN-India door pickup from all major industrial centres - Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and beyond. All repairs are performed in our factory in Vadodara, Gujarat with 180+ experienced engineers and full calibration facilities.
Can Synchronics recalibrate Arun transmitters to Indian ISO/IEC standards?+
Absolutely. All Arun Technology pressure, level, and temperature transmitters are recalibrated to IS 1609 (General requirements for industrial instruments) and IEC 61010-1 standards using traceable reference standards. Synchronics maintains NABL-aligned calibration capability and issues calibration certificates suitable for regulatory audits in pharma, food, and oil-gas sectors across India.
What is the typical repair turnaround for Arun process control modules?+
Most Arun signal conditioning and process controller repairs are completed within 7-10 working days, including full diagnostics, component replacement, calibration, and testing. Critical plant shutdowns receive priority handling with same-week turnaround. Synchronics maintains stock of common Arun replacement components and can provide on-site temporary units to minimise production downtime at Indian manufacturing facilities.
Do you repair older Solartron Mobrey equipment still in operation at Indian plants?+
Yes. Synchronics specialises in legacy Arun and Solartron Mobrey instrumentation dating back to the 1970s-1990s, commonly found in established Indian refineries, chemical plants, and power stations. We source obsolete components, reverse-engineer circuit boards, and integrate vintage systems with modern automation. Our engineers document upgrades to protect long-term plant operations and support compliance with Indian industrial safety regulations.
Does Arun Technology instrumentation suit humid and corrosive Indian industrial environments?+
Arun transmitters and control modules are designed for demanding global conditions, but Indian monsoon humidity and chemical plant corrosion require protective upgrades. Synchronics applies conformal coating, upgrades junction box seals, and re-passivates sensor electrodes to achieve IP67 protection and extended service life in wet wash-down and salt-spray environments common across Indian food processing, pharma, and coastal industrial facilities.
