Addressing Industry Issues
High vibration impact and easy looseness and drift of ordinary instruments
In the vibration environment of ordinary instruments, zero drift, inaccurate data, and loose wiring can lead to control failure, equipment failure, and unqualified factory calibration.
Oil/cutting fluid/dust environment, instruments are prone to clogging and corrosion
Ordinary instruments have clogged diaphragms, corroded casings, short lifespan, 3-6 months of failure, frequent replacement, high maintenance costs, and affect delivery cycles.
Alternating high and low temperatures, poor instrument stability
Ordinary instruments have large temperature drift, low-temperature freezing cracking, high-temperature aging, large data errors, unstable equipment operation, and frequent failures.
Difficult factory performance calibration and inaccurate data
Low manual measurement accuracy, slow efficiency, and untraceable data result in uneven factory quality of equipment and numerous customer complaints.
Strong electromagnetic interference, signal jumping and misoperation
Frequency converter/servo interference, PLC false alarm, false shutdown, equipment action out of control, affecting production continuity and increasing debugging costs.
Cost sensitive, high-precision imported instruments are expensive
The unit price of imported instruments is high, the supply cycle is long, and the after-sales response is slow, which compresses enterprise profits and affects market competitiveness.
