Core Technical Parameters

Product Performance and Features

The Nexisense YDS series demonstrates multiple practical advantages in engineering applications:

• High precision and good stability: Perfect temperature compensation, small zero drift.

• Solid components and plug-in circuit board design: Improves anti-interference capability and reliability.

• Miniaturized and lightweight structure: Sturdy and vibration-resistant, suitable for complex installation environments.

• Range and zero point external continuous adjustable, damping adjustable: Flexible on-site debugging.

• Wide positive and negative migration range (positive 500%, negative 600%): Adapts to various process conditions.

• Strong unidirectional overload protection: Reduces risk of accidental damage.

• No mechanical moving parts: Low maintenance, reduces full lifecycle cost.

• Contact medium diaphragm material optional 316L, TAN, HAST-C, MONEL etc.: Meets different corrosive medium requirements.

• Explosion-proof structure design: Supports all-weather industrial field use.

These characteristics make the YDS series a reliable choice for solving measurement challenges of high viscosity, easy crystallization, and strong corrosive media.

Typical Application Scenarios

• Petrochemical Industry: Level monitoring of reaction kettles, storage tanks, and oil product delivery pipelines, especially suitable for high-viscosity, easy-crystallization or solid-particle-containing slurry media. Remote capillary design effectively prevents direct contact between medium and sensor, extending service life.

• Water Treatment and Municipal Engineering: Filter differential pressure monitoring in sewage treatment plants, liquid level control in water supply networks, and real-time river water level measurement. 316L or higher-grade corrosion-resistant diaphragms can handle complex media such as sewage and chemical agents, ensuring long-term stable output.

• Power Industry: Boiler feedwater system, cooling tower, and desulfurization tower slurry level control have strict requirements on instrument reliability. The YDS series wide temperature range adaptability and strong anti-vibration performance can maintain high-precision output in high-temperature and high-pressure environments and support seamless integration with DCS systems.

• Metallurgy and Mining: Slurry ponds, molten metal levels, and tailings pond monitoring also benefit from the double flange isolation structure, effectively preventing clogging and corrosion.

• Pharmaceutical and Food Industry: Optional hygienic configuration to meet the strict requirements of clean production on medium purity.

• System Integration Projects: As a standardized pressure/level module, it can be directly connected to multi-channel automatic calibration platforms or host computer systems to achieve remote monitoring, data acquisition, and closed-loop control, significantly shortening project commissioning cycles.

  
  

Selection Guide and Integration Precautions

Selection Points:

1. Select the appropriate range according to the maximum differential pressure or liquid level depth, and it is recommended to reserve 10%-20% margin to cope with process fluctuations.

2. For corrosive or high-viscosity media, 316L or higher-grade alloy diaphragms are preferred.

3. For projects requiring digital communication, HART protocol configuration is recommended to support on-site configuration and diagnosis.

4. For explosion-proof environments, the flameproof type or intrinsically safe type requirements must be clearly specified.

5. For batch projects, contact Nexisense for OEM customization, including special ranges, output methods, interface specifications or low-power versions.

Integration Precautions:

• During installation, ensure that the flange is reliably connected to the process pipeline to avoid stress affecting measurement accuracy.

• Capillary laying should avoid sharp bending and high-temperature radiation to keep the filling liquid stable.

• When integrating with PLC, DCS or SCADA, shielded cables are recommended, and signal attenuation compensation should be considered for long transmission distances.

• Regularly check the cleanliness of the diaphragm surface to prevent scaling or crystallization from affecting response speed.

• In high static pressure conditions, confirm the balance valve status before installation to avoid sensor overload damage.

• Zero point and range calibration is recommended to be performed under actual working condition temperature to obtain the best long-term stability.

Nexisense has complete OEM/ODM capabilities and bulk supply system, and can provide customized technical solutions according to the calibration procedures, system architecture and on-site conditions of engineering companies, including communication protocol adaptation, housing protection optimization and tooling integration support.

FAQ

Q1. Compared with traditional single flange products, what are the main advantages of the YDS series double flange differential pressure transmitter?

The double flange structure uses positive and negative pressure side remote isolation design, which is more suitable for closed vessel level measurement. It can effectively eliminate static pressure influence and medium direct contact risk, and has a wider positive and negative migration range, adapting to complex process conditions.

Q2. How does this series of transmitters support HART protocol integration? What is the compatibility with existing DCS systems?

The product natively supports the HART fieldbus protocol and can realize two-way communication, parameter configuration and fault diagnosis through handheld communicators or host software. It has good compatibility with mainstream DCS/PLC systems without additional conversion modules.

Q3. For high-viscosity or easy-crystallization media, what parameters should be focused on during selection?

Priority should be given to flat diaphragm or corrugated diaphragm structure. Diaphragm material is recommended to be 316L or Hastelloy alloy. Installation position should avoid dead corners. Purging or heat tracing functions can be added when necessary.

Q4. How to choose the explosion-proof grade? What is the main application difference between flameproof type and intrinsically safe type?

Flameproof type (dⅡCT5) is suitable for fixed installation in explosive gas environments. Intrinsically safe type (iaⅡCT6) is more suitable for frequent maintenance or portable application scenarios. The specific choice must be determined according to the on-site hazardous area classification.

Q5. What customization services can Nexisense provide in batch procurement projects?

Supports special range, output signal, connector specification, power supply voltage and communication protocol customization. OEM versions can also be developed according to project requirements, including housing identification, protection level optimization and batch test report support.

Q6. How to reduce zero point drift and temperature influence during installation?

Vertical installation is recommended. Capillary laying should be kept horizontal or slightly downward inclined to avoid drastic changes in ambient temperature. After installation, zero point calibration should be performed under actual working conditions, and fine adjustment should be made using external adjustable functions.

Q7. Compared with ultrasonic or radar level gauges, in which working conditions does the double flange differential pressure transmitter have more advantages?

In high pressure, high temperature, strong corrosion or high viscosity medium environments, the double flange differential pressure transmitter has more reliable isolation structure, stronger anti-interference ability, and lower maintenance cost. It is especially suitable for flow or level applications that require high-precision differential pressure measurement.

Q8. How to maintain the best performance after long-term operation?

Regularly check the cleanliness of the diaphragm surface and sealing condition, and flush with clean medium. Perform zero point and range calibration every 6-12 months. When abnormal drift is found, check the capillary filling liquid status in time to avoid mechanical damage.
