Unafraid of viscous blockages, accurately sensing pressure—nanofilm flat-diaphragm pressure transmitter specially designed for harsh media.

2025-08-07

 

In the kilometer-deep boreholes of oil drilling, viscous mud swirls and churns, carrying fragments of rock along with it; in the reaction vessels of chemical plants, high-viscosity materials surge like molten lava; and in front of the cutterhead of tunnel-boring machines, sand, soil, and rock debris cascade down like a waterfall... Under these complex operating conditions, conventional sensors often suffer from drawbacks such as sediment blockage, impact damage, poor anti-interference capability, oil leakage during filling, and low durability and reliability—rendering them unable to meet the demands for stable operation in such challenging environments.

Sensor Nobleman S500 nanofilm flat-diaphragm pressure transmitter, used with... Unique hard-flat membrane anti-clogging design + nanofilm technology This combination of approaches has given rise to a brand-new solution that is perfectly suited for complex operating conditions—completely eliminating the risk of medium blockage at the physical structure level, while leveraging atomic-level fusion technology to ensure long-term operational stability. Coupled with a non-oil-filled design that eliminates the risk of leakage, this solution has become an indispensable tool for pressure measurement in challenging and complex environments.

 

01  Core product features: Hard flat membrane anti-clogging + nano-thin-film core—precise and reliable performance to meet even the toughest challenges.

1. Hard flat film anti-blocking, oil-free, suitable for viscous and sanitary media.

Featuring a special structure made of hard, flat-diaphragm stainless steel, this product boasts high strength and excellent impact resistance, making the diaphragm highly resistant to damage. The contact surfaces for the medium are smooth and free of dead corners, enabling it to handle complex media such as high-viscosity slurries and particle-laden fluids without hesitation. This design fundamentally prevents blockage of pressure-tapping holes and damage to the diaphragm, ensuring long-term stable operation. Additionally, the device features a non-oil-filled design, eliminating any risk of leakage from oil-filled media.

II. Nanofilm Technology—Accuracy as Steady as a Rock

The core sensing element employs an internationally advanced patented nano-film atomic deposition technology. The sensitive material is atomically integrated with the elastomer, eliminating the need for organic resins or adhesives. This design effectively resists media corrosion and diaphragm fatigue, ensuring long-lasting and reliable performance. The product boasts a measurement accuracy of ±0.1%FS, an annual drift of no more than ±0.1%FS/year, and a full-scale temperature drift of ≤0.03%FS/℃, demonstrating exceptional stability.

3. Adaptable to a wide temperature range and capable of covering complex scenarios.

Utilizing sensitive materials with an extremely low temperature drift coefficient and a specialized elastomer structure, the sensor covers a measurement range from 0 to 100 kPa to 150 MPa. It can directly withstand high temperatures up to 350°C and offers protection against overpressure up to twice the full-scale range and against destructive pressures up to three times the full-scale range. Featuring an integrated design, compact size, and excellent vibration resistance, this sensor is well-suited for harsh environments characterized by humidity and intense vibrations—such as those found in the rubber, synthetic fiber, oil drilling, chemical processing, and tunneling industries.

4. Strong anti-interference capability, supports multiple outputs.

The EMC electromagnetic radiation immunity reaches 100 V/m, enabling it to handle complex electromagnetic environments such as those created by variable-frequency devices and high-voltage motors. It supports multiple output signal types, including mV, 4-20mA, and 1-5VDC, allowing flexible integration with industrial control systems such as DCS and PLC.

5. Safe and reliable, with a compact structure.

Oil-free design completely eliminates the risk of leakage. Compact size and lightweight for easy installation and integration.
