FREDERICKS Product Lines We Repair
Our engineers are trained on the full FREDERICKS product range. Below are the major product families we service.
Series 1000 / 2000 Differential Pressure Switches
Industrial-grade DP switches for HVAC systems, filter monitoring, and process control. Common failures include diaphragm rupture, switch contact oxidation, and pressure tubing blockages that prevent accurate setpoint detection.
RH/Humidity Transmitters and Sensors
High-accuracy relative humidity and temperature sensors for pharmaceutical, food, and electronics manufacturing. Typical issues include capacitive sensor drift, analog output circuit failure, and display LCD degradation in high-moisture environments.
Flow Switches and Flow Rate Transmitters
Mechanical and electronic flow monitoring for water cooling loops, oil circulation, and gas distribution. Frequent faults include paddle/rotor jamming, analog electronics PCB corrosion, and cable gland seal degradation.
Pressure Transmitters and Transducers
4-20mA and 0-10V pressure measurement instruments for compressors, boilers, and hydraulic systems. Common repair needs: zero drift calibration, 4-20mA loop circuit failure, connector corrosion, and internal diaphragm sensor replacement.
Electronic Pressure Switches
Solid-state switching with adjustable setpoints for compressor unload control and system protection. Failures include tripped relay contacts, failed PCB voltage regulator, misaligned zero offset, and weatherhead seal leakage.
Flow Indicator Panels and Control Modules
Integrated display and switching modules for monitoring multiple fluid streams in parallel processes. Issues: LCD segment failure, internal relay stiction, communication protocol errors, and power supply degradation.

Common FREDERICKS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FREDERICKS equipment arriving at our workshop.
- ✓Differential pressure diaphragm rupture and leakage — Fredericks DP switch diaphragms fail from overpressure spikes, thermal cycling, or prolonged exposure to corrosive process gases. Rupture allows pressure equalization across the diaphragm, eliminating switch sensitivity and causing false no-flow/clogged-filter alarms.
- ✓4-20mA transmitter loop open or shorted — Fredericks pressure and humidity transmitters experience 4-20mA circuit failure due to corroded terminal blocks, failed current-limiting resistors, or damaged transducer IC (often LM317 or similar). Moisture ingress into the connector causes intermittent opens.
- ✓Humidity sensor capacitive drift and offset error — Fredericks RH sensor capacitive elements drift after years of operation in high-humidity environments or exposure to process chemicals that degrade polymer film. Drift causes 5-10% reading inaccuracy, failing dew-point control in pharma and semiconductor cleanrooms.
- ✓Flow switch paddle seized or bearing worn — Fredericks mechanical flow switches accumulate sediment, corrosion products, or biological growth on the rotor paddle, preventing free movement. Bearing wear in extended-duration installations (2000+ operating hours) causes paddle drag and reduced sensitivity.
- ✓Relay contact chatter and switching intermittency — Fredericks electronic pressure switches use internal reed relays or solenoid contactors that fail from contact bounce during setpoint crossing, arc pitting from inductive loads, or mechanical relay armature binding. Intermittency causes nuisance trip-outs in safety interlocks.
- ✓LCD display segment failure and readability loss — Fredericks transmitter and panel displays fail due to extended backlight operation, internal LCD driver IC failure, or thermal cycling that fractures segment conductors. Moisture and temperature swings in uncontrolled plant environments accelerate LCD degradation.

Frequently Asked Questions — FREDERICKS Repairs
Do you repair Fredericks equipment anywhere in India?+
Yes. Synchronics repairs the complete Fredericks portfolio including DP switches, humidity transmitters, flow switches, pressure transducers, and electronic control modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all major industrial cities. All repairs are performed at our 180-engineer facility in Vadodara, Gujarat.
How do I troubleshoot a Fredericks DP switch showing zero differential in a clean filter?+
A DP switch reading zero even with a clean/new filter typically indicates a diaphragm rupture or tubing blockage. Synchronics advises: (1) verify tubing for kinks or sediment using air pressure pulse test; (2) check if diaphragm has leaked (oil residue on case indicates rupture). We recommend shipping the unit for controlled pressure testing and diaphragm replacement with OEM seals, plus full recalibration to your setpoint.
What calibration standards does Synchronics use for Fredericks transmitters?+
Fredericks humidity, pressure, and flow transmitters are calibrated using NIST-traceable reference standards and deadweight testers. We perform two-point or three-point calibration (depending on application criticality) and document all results with certificate. For pharma/food applications requiring GMP compliance, Synchronics provides calibration data logs and traceability documentation.
Can Fredericks switches be repaired or must they be replaced?+
Most Fredericks switches can be repaired cost-effectively. Diaphragm, relay, and bearing replacements restore 95%+ of failed units to OEM performance at 40-60% of new unit cost. However, if the pressure housing is cracked or the switching mechanism is worn beyond tolerance, replacement is recommended. Synchronics assesses repairability during diagnosis before committing to repair.
How long does Fredericks sensor repair typically take?+
Standard Fredericks repair turnaround is 5-7 working days: diagnostics (1 day), parts sourcing (1-2 days), repair and calibration (2-3 days), final testing (1 day). Expedited repairs can be completed in 2-3 days if parts are in stock. Synchronics maintains a parts inventory for common Fredericks modules to minimize delays.
How do I send my FREDERICKS 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 FREDERICKS 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 FREDERICKS 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 FREDERICKS 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.
