ANDERSON INTRUMENT Product Lines We Repair
Our engineers are trained on the full ANDERSON INTRUMENT product range. Below are the major product families we service.
Anderson Liquid-Filled Pressure Gauges
Glycerin-filled gauges designed for vibration-heavy environments like pumping stations and compressor rooms. Common issues include internal glycerin leakage, pointer stiction, and movement wear from pressure cycling.
Anderson Dry Pressure Gauges
Industrial dry-case pressure indicators for steam lines, hydraulic systems, and air applications. Typical failures include needle sticking, dial face fading, case seal degradation, and dial movement mechanical wear.
Anderson Electronic Pressure Transmitters
4-20mA output pressure transducers for DCS and PLC integration in refineries and chemical plants. Common faults include zero/span drift, connector corrosion, signal noise, and temperature compensation errors.
Anderson Temperature Sensors and Wells
Thermowell assemblies and temperature sensing elements for boilers, reactors, and exhaust streams. Repairs address well rupture, thermocouple junction oxidation, insertion probe separation, and calibration loss.
Anderson Pressure Switches
SPDT and adjustable-setpoint switches for compressor unloading, pump protection, and alarm applications. Common failures include contact welding, diaphragm rupture, spring fatigue, and setpoint drift over time.
Anderson Differential Pressure Indicators
Visual and electronic DP gauges for filter monitoring, level detection, and flow verification in water treatment and HVAC systems. Typical issues include magnet wear, pointer lag, and seal degradation.

Common ANDERSON INTRUMENT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ANDERSON INTRUMENT equipment arriving at our workshop.
- ✓Pressure gauge pointer stiction and sluggish response — Anderson gauge movements experience internal friction from dust, moisture, or glycerin degradation in sealed cases. Pointer binding occurs when movement jewels or pivot points corrode or accumulate particulate matter over years of service.
- ✓Electronic pressure transmitter zero/span drift and signal noise — Anderson D-series transmitters drift when internal conditioning circuits degrade, connector pins oxidize, or temperature compensation loses calibration. Signal noise results from EMI coupling in long cable runs or corroded terminal blocks in high-humidity plant environments.
- ✓Thermowell rupture and thermocouple probe detachment — Anderson thermowell materials (304 or 316 stainless) fail under high-frequency vibration, thermal cycling stress, or corrosive media (chlorine, hydrogen sulfide). Probe separation occurs when ceramic insulators crack or socket welds fail under temperature shock.
- ✓Pressure switch contact welding and sticky setpoint adjustment — Anderson PS switches contact weld when inductive loads cause arc energy during switching, or when contacts remain closed under overpressure for extended periods. Setpoint creep results from spring stress relief or diaphragm hardening after years of cyclic pressure exposure.
- ✓Differential pressure gauge magnet demagnetization and stuck indicator — Anderson DP gauges use permanent magnets for visual indication that lose strength when exposed to external magnetic fields or elevated temperatures above 60°C. Stuck indicators result from damping fluid loss or frozen pivot mechanisms.
- ✓Glycerin leakage from sealed pressure gauge case — Anderson liquid-filled gauges lose glycerin through needle port seal degradation, bottom connection fitting corrosion, or case window gasket compression set. Leakage accelerates in high-temperature environments (>50°C ambient) where glycerin viscosity reduces seal effectiveness.

Frequently Asked Questions — ANDERSON INTRUMENT Repairs
Do you repair Anderson Instrument equipment anywhere in India?+
Yes. Synchronics repairs the complete Anderson Instrument product range across all of India. We service pressure gauges, electronic transmitters, temperature sensors, thermowells, and pressure switches from our Vadodara facility. We offer PAN-India pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Kolkata, and all other industrial cities with same-day diagnostic reporting.
Can you recalibrate Anderson pressure gauges to NIST standards?+
Yes. Synchronics performs full NIST-traceable calibration on all Anderson gauge models using certified dead-weight testers and digital pressure standards. We calibrate across the full operating range, document accuracy certificates, and adjust pointer zero/span as required. Turnaround is typically 3-5 working days from receipt.
What is the typical lifespan of an Anderson liquid-filled pressure gauge before repair becomes necessary?+
Anderson gauges typically operate 5-10 years before seal degradation or movement wear requires service. In high-vibration applications (compressor discharge, pump outlets), pointer stiction and glycerin breakdown occur faster - often within 3-5 years. Synchronics recommends preventive maintenance every 2-3 years in harsh environments to extend reliability.
Do you stock Anderson Instrument replacement parts and movement assemblies?+
Synchronics maintains inventory of Anderson movement assemblies, diaphragms, switch contacts, connector plugs, and seal kits. For specialized parts like thermowell materials or electronic transmitter circuit boards, we source directly from Anderson or approved suppliers within 5-7 working days. Emergency availability can be arranged for critical plant downtime situations.
Can you repair Anderson electronic transmitters that show erratic 4-20mA output?+
Yes. We diagnose Anderson D-series transmitter faults including zero/span drift, temperature compensation errors, and signal noise. Our engineers perform circuit-level repair of conditioning amplifiers, replace degraded capacitors, recalibrate zero/span potentiometers, and conduct bench testing across temperature and pressure ranges before return. Most transmitter repairs are completed within 7-10 days.
How do I send my ANDERSON INTRUMENT 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 ANDERSON INTRUMENT 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 ANDERSON INTRUMENT 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 ANDERSON INTRUMENT 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.
