Product Functional Features

Non-contact high-precision measurement based on the eddy current principle

The core technology is based on the principle of electromagnetic induction. The coil inside the sensor probe generates a high-frequency electromagnetic field. When approaching a metal target, eddy currents will be induced on the target surface, thereby affecting the impedance of the coil. This impedance change is measured by the IQS900 signal conditioner and linearly converted into a voltage or current signal proportional to the gap.

The core advantage lies in its complete non-contact nature, which avoids friction and wear with the tested part, and has an infinitely long theoretical service life. TQ402 111-402-000-013 A1-B1-C075-D000-E050-F2-G050-H05 is especially suitable for measuring the vibration and displacement of high-speed rotating machinery, without imposing additional load or wear on the operating equipment.

Outstanding environmental adaptability and robustness

The ultra-wide operating temperature range enables the sensor body to operate within a temperature range of -40°C to +180°C, and it can withstand up to 220°C in the short term. This enables Proximity Transducers to be directly installed near high-temperature components such as steam turbines and gas turbines without the need for complex cooling systems.

The robust physical structure features a probe head made of Torlon® (polyamide-imide) material, a high-performance engineering plastic with extremely high mechanical strength, wear resistance and high-temperature resistance. The shell is made of AISI 316L stainless steel, providing excellent corrosion resistance.

The powerful protection capability is achieved by the sensor head and integrated cable reaching an IP68 protection level, which is completely dust-proof and can be immersed in water for a long time. It can cope with harsh industrial environments such as moisture, oil stains, and dust. The optional flexible stainless steel hose with FEP sheath for TQ402 111-402-000-013 A1-B1-C075-D000-E050-F2-G050-H05 provides additional protection against impact, pressure, scratches and chemical corrosion.
