Q1: What unique advantages does this high-temperature dedicated level gauge have over ordinary stainless steel magnetic level gauges?

A: This model is fully optimized for thermal working conditions in structure, accessories and materials. It adopts temperature-grated magnetic flaps, professional high-temperature anti-leakage sealing structure and thermally stabilized stainless steel materials, which can effectively resist high-temperature aging, thermal distortion and steam corrosion. It maintains stable long-term operation in continuous high-heat environments where ordinary standard gauges cannot work normally.

Q2: How to choose the correct magnetic flap type for different temperature zones?

A: We provide two professional grades. Nylon-aluminum composite flaps are suitable for medium and low temperature scenarios below 150°C with cost-effective performance. Full-metal high-temperature flaps are mandatory for working conditions above 150°C up to 400°C to avoid thermal aging and sticking.

Q3: Will high-temperature fluid thermal convection affect float accuracy?

A: No. The high-temperature optimized float structure is specially designed for thermal fluid fluctuation. It can automatically adapt to tiny viscosity changes and thermal convection disturbance of high-temperature media, maintaining stable buoyancy balance and precise level tracking.

Q4: Can the transmitter and switch accessories work stably under 400°C long-term operation?

A: Yes. All supporting electrical accessories are high-temperature calibrated versions. They adopt anti-high-temperature aging components to ensure stable signal output and no drift under persistent thermal load.

Q5: Does high-temperature operation require special sealing configuration?

A: Our integrated full-welded structure matches high-temperature adaptive sealing design, which can effectively resist thermal expansion and high-temperature medium erosion without frequent replacement of sealing parts, greatly reducing maintenance frequency.

Q6: Can this gauge adapt to alternating hot and cold temperature cycles?

A: Absolutely. The overall stainless steel structure has stable thermal expansion coefficient, which can withstand repeated temperature rise and fall impact, suitable for batch production and intermittent heating process conditions.
