Under high-temperature operating conditions, the TT20 high-temperature pressure-guided level transmitter, with its stainless steel cable drum-type structure, perfectly solves the technical challenge of ultra-high-temperature water level measurement. As a flagship product of Xi'an Shenghongchuang Instrumentation Co., Ltd., its outstanding high-temperature resistance and precise measurement capability provide reliable solutions for level monitoring in industries such as petrochemicals and electric power.

I. Definition and Overview: Technical Principle of the High-Temperature Pressure-Guided Level Transmitter

The TT20 high-temperature pressure-guided level transmitter adopts the pressure-guided measurement principle, transmitting the medium pressure to the sensor core component through a stainless steel cable drum-type structure. Its unique design can withstand a continuous operating temperature of up to 200℃, and can endure extreme working conditions of 300℃ in the short term. Compared with ordinary level transmitters, TT20 series products can still maintain a measurement accuracy of ±0.5%FS in high-temperature environments, thanks to the high-temperature compensation algorithm and special alloy diaphragm technology independently developed by Xi'an Shenghongchuang. This product series includes multiple models such as JYB-KO-Y3 and CYB31D, meeting the ultra-high-temperature water level measurement needs of different industrial scenarios.

III. Application Scenarios: Practical Solutions for High-Temperature Operating Conditions

In the monitoring of slurry systems in catalytic cracking units in the petrochemical industry, traditional level gauges often become inaccurate due to the influence of 350℃ high-temperature steam. The LHBU model transmitter customized by Xi'an Shenghongchuang for a large refinery successfully achieved continuous fault-free operation for 12 months by installing heat dissipation fins and dual thermal insulation layers. Similar cases also include:

• Boiler drum water level monitoring in the electric power industry (using model HD504)
• Molten metal level control in the metallurgical industry (using the HB874 high-temperature dedicated model)
• Heat transfer oil storage tanks in solar thermal power generation systems (configured with the ZD-136P explosion-proof version)

IV. Procurement and Selection Guide: Essential Checklist for Technical Evaluation Personnel

When selecting a high-temperature pressure-guided level transmitter, technical evaluation personnel should focus on:

1. Matching degree between medium temperature and pressure curve (it is recommended to leave a 20% safety margin)
2. Process connection method (thread/flange) and on-site installation conditions
3. Whether explosion-proof certification is required (for example, BPH30D has passed ATEX certification)
4. Output signal type (4-20mA/HART/Modbus, etc.)
5. After-sales technical support capability (Xi'an Shenghongchuang provides 24-hour response)
