Product Description Product DescriptionIntroducing the cutting-edge PDS873 remote pressure transmitter by Cold Valley Intelligent Technology (Shanghai) Co., Ltd. This innovative device is engineered to provide unmatched precision in pressure measurement, seamlessly converting pressure readings into either a 4-20mA d.c. current output, enhanced with superimposed HART communication, or sophisticated PROFIBUS-PA and FF communication signals. Experience the future of process control with advanced remote setting capabilities, real-time monitoring, and a suite of intelligent functions easily accessible through state-of-the-art communication devices. Elevate your operational efficiency and control with this technological marvel.FeaturesHigh StabilityThe PDS Intelligent Transmitter offers remarkable precision, boasting a basic accuracy of 0.04%FS, with the capacity to achieve up to 0.025%FS. This incredible accuracy is sustained at 99.9%, even after a decade of continuous use, reducing maintenance expenses significantly. Constructed with a robust metal shell and entirely sealed measurement components, it confidently withstands extreme chemical and mechanical stresses. Its exceptional resilience includes potent anti-electromagnetic interference capabilities and a lightning protection feature, ensuring the PDS Transmitter remains both highly stable and reliable.Intelligent DiagnosisThe PDS Intelligent Transmitter is equipped with an advanced integrated diagnostic function, which continuously monitors its operational process and status in real time. If a pre-defined event threshold is surpassed, the transmitter triggers a fault alarm state, outputting an alarm current (3.6 or 22.8mA) to deliver control signals for system interlocking or the SIS security system. During failure, the LCD screen prominently displays 'Err', automatically analyzing and identifying the faulty component, thereby simplifying maintenance, repair, and replacement operations.The diagnostic capability can also be activated via HART, FF, PA, and other communication protocols, with alarms displayed as either warnings or fault protection currents. It automatically assesses the health of the SENSOR, ROM, RAM, EEPROM, and software. Should an electronic unit or measurement element fail, the defective component can be swiftly replaced on-site without the need for re-adjustment.SimulationThe transmitter's simulation function adeptly replicates the process state to acquire measurement data, while also verifying the connection and output status of the transmitter circuit. Simulation output parameters encompass pressure, sensor temperature, and electronic temperature. Options for simulation output modes include fixed value simulation or linear function simulation. Throughout the simulation process, the transmitter's output remains unaffected by field pressure changes, promptly returning to its normal measurement state following a key operation or a power cycle restart.Product ParametersBasic accuracy: Experience precision at its finest with an impressive basic accuracy of ±0.04%, which can be maximized to ±0.025% for unparalleled reliability.Range ratio: An extraordinary range ratio of 100:1, providing flexibility and adaptability for diverse industrial needs.Response time: Enjoy rapid response times of 90ms, with data refreshing at a brisk 50ms, ensuring seamless process control.Range range: Handle differential pressure with ease, spanning from 0-100 Pa up to a robust 14MPa.Pressure of 0-1 kPa-70MPa: Master pressures from 0-1 kPa to a formidable 70MPa, catering to a broad spectrum of industrial applications.Output signal: Benefit from versatile output signals with 4-20 mA superimposed HART protocol communication, fully compatible with versions HART6.0 and HART 7.0.PROFIBUS-PA fieldbus communication: Leverage state-of-the-art PROFIBUS-PA fieldbus communication, version 3.02, for smooth and efficient data transmission.FF Fidbus Communication: Engage with the latest FF Fidbus Communication, version 6.1.1, for robust and reliable connectivity.Overload limit: Stay secure with an overload limit for differential pressure set at an impressive 42MPa.Pressure of 105MPa: Depend on a solid pressure handling capacity of up to 105MPa for demanding environments.Effect of the static pressure: Maintain stability with a negligible effect of static pressure at 0.03%FS / 16MPa, ensuring precision even under significant static pressures.Temperature range: Operate confidently within an extensive ambient temperature range of -40oC to 80oC, with specific considerations for explosion-proof temperatures outlined in the grade specifications.Process temperature: Adapt to a wide process temperature range, stretching from -90oC to an impressive 700oC, suitable for various industrial applications.LCD temperature: The LCD functions optimally between -35oC and 80oC, providing consistent readability and operation.Long-term drift: Trust in long-term stability, with a drift as minimal as ±0.1%FS over a decade, assuring high accuracy over time.Temperature Effect: Experience minimal temperature effects with (0.06 * r + 0.01)% over a 28oC range, from -40oC to 80oC, maintaining precision in varying conditions.Explosion-proof grade: NEPSI: Safeguard operations with Type Ex iaIICT4 Ga, suitable for ambient temperatures from -40oC to 60oC, ensuring secure functionality.NEPSI: Intrinsic Ex iaIICT6 Ga: This grade provides robust protection for temperatures ranging from -40oC to 40oC, delivering peace of mind in sensitive environments.NEPSI: Explosive type Ex dIICT6 Gb: Accommodate a range of ambient temperatures from -40oC to 60oC with this explosion-proof grade.NEPSI: Dust explosion Ex tD A21 IP67 T85oC: Achieve superior dust explosion protection with NEPSI certification, ensuring safety and compliance.NEPSI: 'n' explosion-proof Ex nACT6 Gc: Experience reliable protection for ambient temperatures between -40oC and +60oC, reinforcing operational safety.ATEX: Ben Ex II 1 G Ex iaIICT4 Ga: Elevate safety standards with ATEX certification, empowering operations with intrinsic safety under the Ex iaIICT4 Ga designation.ATEX: Burst Ex II 1 / 2 G Ex dbIICT6-T 4 Ga / Gb: This burst-proof ATEX certification secures environments for versatile applications, adhering to the Ex dbIICT6-T 4 Ga / Gb standards.IECEx: Intrinsic safety Ex iaIICT4 Ga: Equip your facility with IECEx certification, ensuring intrinsic safety with Ex iaIICT4 Ga compliance.IECEx: Burst Ex dbIICT6-T 4 Ga / Gb: Embrace the reliability of IECEx burst certification, safeguarding environments with Ex dbIICT6-T 4 Ga / Gb specifications.Company ProfileCold Valley Intelligent Technology (Shanghai) Co., Ltd. stands proudly as a distinguished member enterprise of the reputable Hanshan (Cold Mountain) Intelligent Technology Co.(hereinafter known as Hanshan Intelligent Technology Co., Ltd. group), firmly established its foundational roots amidst the dynamic landscape of Shanghai in 2013.Our founding team comprises seasoned experts from top-tier international automation companies, boasting over 20 years of profound expertise in automation, engineering, and a decade dedicated to consulting and executing sophisticated digital solutions.
