Suzhou Dingluxuan Sensor Technology Co., Ltd. specializes in the R&D, manufacturing and sales of sensors, precision instruments, and high-temperature insulating ceramic products. We serve industries such as photovoltaic & semiconductor, industrial heat treatment, metallurgy, and glass & ceramics, providing end-to-end service and integrated temperature-measurement and control solutions — from core sensing elements and ceramic insulating parts to complete systems.
Annealing, quenching, sintering and calcining furnaces require continuous long-term temperature measurement. Sensing elements must withstand high furnace temperatures while remaining easy to install and maintain, with insulating parts protecting the measurement loop.
Metallurgy and salt-bath applications run hot with strong corrosion. Molten salt and metal melts severely erode protection tubes; ordinary thermocouples see a markedly shortened service life in such conditions.
During PV and semiconductor manufacturing, ingot furnaces, single-crystal furnaces and diffusion furnaces operate above 1300°C for long periods. Sensing elements demand high temperature resistance, thermal-shock resistance and measurement accuracy.
Glass and ceramic kilns run hot and continuously with strict product-cleanliness requirements. Sensing elements and in-furnace insulating parts must combine high-temperature and thermal-shock resistance with zero product contamination.

Heating and cooling control in water dispensers relies on temperature sensors. Unlike industrial use, dispensers demand hygienic safety, reliable water-proofing and reasonable cost.
Hydro generators run continuously; temperatures of bearings, stator windings and transformers directly affect unit safety. Reliable sensing is essential for accurate protection trips.
A sensor only produces a temperature-dependent electrical signal. Readable values require matching instruments — correct calibration type, wiring and extension/compensation cable selection.
When troubleshooting a pressure sensor on site, a multimeter is the most convenient tool. Three measurement points quickly reveal whether the sensor or its wiring is at fault.
