CHUNG INSTRUMENT ELECTRONICS Product Lines We Repair
Our engineers are trained on the full CHUNG INSTRUMENT ELECTRONICS product range. Below are the major product families we service.
Digital Temperature Controllers
CHUNG INSTRUMENT's flagship PID temperature control units with analog and digital inputs. Common failures include thermocouple failures, relay output sticking, and calibration drift after extended thermal cycling in high-temperature applications.
Process Indicator Meters
Multi-function digital panel meters for voltage, current, frequency, and power monitoring. Typical faults involve LCD segment failures, input terminal corrosion, and signal conditioning circuit degradation in humid or corrosive industrial environments.
Pressure and Level Transmitters
4-20mA analog output transmitters for hydraulic and pneumatic systems. Common issues include sensor calibration loss, 4-20mA loop failures, and electrical isolation degradation in harsh plant conditions.
Heating Controller Modules
SSR-based and relay-based heating control units for industrial furnaces and ovens. Frequent failures include solid-state relay failure modes, zero-crossing detection circuit issues, and thermal protection sensor misalignment.
Signal Conditioning and Isolation Modules
Galvanic isolation and amplification modules for sensor signals in electrically noisy plant environments. Typical problems include optocoupler aging, capacitor electrolyte leakage, and input filter component failure.

Common CHUNG INSTRUMENT ELECTRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHUNG INSTRUMENT ELECTRONICS equipment arriving at our workshop.
- ✓Temperature controller unresponsive or showing ERR1 code — CHUNG INSTRUMENT thermocouples degrade or become damaged in high-temperature zones. Thermocouple connector oxidation and cold-junction compensation circuit failures are common after 5-7 years of continuous operation in textile dyeing and heat treatment plants.
- ✓Relay output stuck or chattering intermittently — CHUNG INSTRUMENT relay coils experience contact erosion and mechanical wear under repetitive switching in heater and motor control circuits. Dust ingress and manufacturing contaminants accumulate in relay contact chambers, causing intermittent switching failures.
- ✓LCD display showing partial segments or complete blackout — CHUNG INSTRUMENT process indicator meters suffer LCD degradation from temperature extremes and humidity in humid Indian climates. Segment driver IC failures and LCD bias voltage circuit capacitor aging cause display fading or segment dropout.
- ✓4-20mA output not responding or stuck at 4mA minimum — CHUNG INSTRUMENT transmitter circuits fail when output terminals corrode or when the digital-to-analog conversion IC (typically a 12-bit DAC) develops internal faults. Loop current source circuit failures prevent normal signal transmission in long cable runs common in Indian steel and petrochemical plants.
- ✓Heating controller SSR fails to energize heating element — CHUNG INSTRUMENT solid-state relay gates fail due to thermal stress cycling in continuous furnace operations. Gate drive circuit failures and optocoupler degradation prevent proper firing of the triac or thyristor in the SSR output stage.
- ✓Signal isolation module not providing electrical isolation or amplifying signal incorrectly — CHUNG INSTRUMENT isolation modules experience optocoupler aging, causing reduced gain and loss of galvanic isolation in electrically noisy environments. Coupling capacitors in signal conditioning circuits fail due to age and electrolytic leakage, distorting sensor signals.
