Key features
Built-in amplifier: no external charge amplifier is required, standard voltage signal is directly output, suitable for modern DCS or monitoring systems.
Good frequency response range: effective response from 2 Hz to 1000 Hz, covering the common vibration frequency band of rotating machinery.
Easy installation: bottom threaded connection structure, suitable for equipment housing or rack with limited space.
Strong power supply adaptability: supports wide range constant current power supply, easy system integration.
High reliability: adopts all-metal sealed structure, suitable for long-term continuous operation in industrial environment.


Typical cooperation cases
Oil and gas extraction: The water injection pump group of an offshore drilling platform in the North Sea of Norway is easy to wear due to the particles in the medium. TQ412 detected the micro cracks in the bearing raceway through the high-frequency spectrum of acceleration and stopped the machine for replacement 4 weeks in advance, avoiding the loss of millions of dollars caused by the interruption of offshore operations.
Power operation and maintenance: A natural gas combined cycle power plant in Texas, USA, deployed TQ412 at the gas turbine compressor bearing, connected to the DCS system through 4-20mA signal, combined with trend analysis, found that the vibration value rose slowly, and finally located it as an imbalance caused by blade fouling, avoiding unplanned shutdown.
Chemical production: In the catalytic cracking unit of a large refinery in Saudi Arabia, TQ412 is used to monitor the high-temperature regenerator fan. Its IP68 protection and wide temperature design solve the problem of traditional sensors failing due to high temperature, and it has been running continuously for 2 years without failure.
