Product Description

Product Description

Introducing the PDS813, a pinnacle of precision in pressure measurement tailored for the paper-making industry. This high-accuracy pressure transmitter boasts a unique process connection that is meticulously designed to enhance efficiency. Its pressure-sensing element is strategically positioned at the forefront, with a diaphragm that aligns seamlessly with the pipe's inner wall. This innovative design effectively eliminates the common issue of blockages caused by high-viscosity media, making it an ideal solution for paper-making and similar applications where blockages are prevalent. The PDS813 excels in converting detected pressure signals into a reliable 4-20mA direct current output, enhanced with superimposed HART communication, as well as supporting PROFIBUS-PA and FF communication signals. This versatile functionality empowers users with the ability to perform remote settings and monitoring, unlocking a new level of operational convenience and control through advanced communication devices.

Features

High stability
The PDS high-precision intelligent transmitter boasts an exceptional basic accuracy of 0.04%FS, which can be refined to an impressive 0.025%FS. Even after a decade of relentless use, it retains a staggering 99.9% accuracy. This remarkable consistency translates to significant maintenance cost savings. Encased in a robust metal shell with fully sealed measuring components, it gracefully withstands extreme chemical and mechanical stresses. Its formidable anti-electromagnetic interference capability, coupled with a sophisticated lightning protection feature, ensures unparalleled stability and reliability.

Intelligent diagnosis
Equipped with an integrated intelligent diagnosis feature, the PDS transmitter vigilantly monitors its operational process and internal status in real-time. Upon surpassing predefined event thresholds, it shifts to a fault alarm mode, emitting an alarm current of either 3.6 or 22.8mA. This crucial signal facilitates system interlocking or activates the SIS security framework. During malfunctions, an 'Err' message is instantly displayed on the LCD screen, alongside a detailed analysis pinpointing faulty components, simplifying maintenance, and streamlining repair and replacement procedures.
The diagnostic capabilities can be activated via HART, FF, PA and other communication protocols, with alarms articulated as warning or fault protection currents. It autonomously evaluates SENSOR, ROM, RAM, EEPROM, and software integrity. In cases of electronic unit or measurement element failure, direct on-site component replacement is possible, circumventing the need for recalibration.

Simulation
The versatile simulation function of the transmitter is adept at emulating process states to derive measurement data. It also serves as a vital tool for verifying circuit connection and output status. Simulation output parameters encompass pressure, sensor temperature, and electronic temperature. Modes available include fixed value simulation and linear function simulation. During simulation, transmitter output remains unaffected by field pressure changes, reverting to normal measurement mode after key operation or a power cycle of the transmitter.
