Intelligent diagnosis and simulation

PDSIntelligent transmitters have integrated diagnostic functions that can monitor the process and itself at regular intervals. After exceeding the defined number of events, it can send relevant measurement values and respond simultaneously, starting from a simple 'numerical indicator'”It has become a 'numerical analyzer'.

ØConstant or variation simulation: pressure value, sensor temperature, electronic component temperature

The manifestation of advanced electronic technology on PDS

ØOverlimit monitoring is implemented by an event counter. When the pressure value exceeds the limit or an error signal is generated, its frequency, time, and amplitude will be recorded and reported as abnormal events.

ØYou can freely set 3 limit values for executing pre-set alarms and temperature monitoring. Use unrecoverable instantaneous actual values to record input pressure, sensor temperature, electronic unit temperature, as well as the minimum and maximum drift relative to the normal range. This can provide information about the operating status, process temperature, and ambient temperature of PDS.

ØThe simulation function is directly built into the transmitter, which can check the electronic part of the transmitter and the entire circuit based on defined values to obtain important information such as whether the electronic part of the transmitter is working properly? At what pressure does overpressure response occur? Is the regulating circuit functioning properly? Are all display functions working?

ØIf an error signal from the electronic unit or measuring element is detected on the transmitter, the faulty component can be easily replaced on site without the need for recalibration.

Friendly operating interface

Flexibility has always been a standard feature of PDS smart transmitters. You can adjust the zero point, range, and damping as needed at any time, without the need for a pressure source or standard equipment, allowing for arbitrary tuning. The large LCD screen and buttons make on-site calibration accurate and convenient, without affecting response characteristics and consistency errors. The zero and full values can be directly set through the local buttons. Physical units or percentages can also be freely selected. Whether it's local debugging or remote control through HART, PROFIBUS-PA, or PDM, everything you need can be done. The modular structure of PDS can provide similar benefits: due to the secure storage of sensor data in the measuring components, the circuit can be replaced without any problems in the event of a malfunction. This means that quick and simple on-site repairs can be carried out, and storage costs can be reduced.

On site calibration is easier

By using three buttons and a high contrast LCD display, all parameters can be quickly and easily inputted on-site. You can set the output signals for minimum, maximum, damping, and error events on site without opening the transmitter cover. This means that moisture will not enter the interior of the transmitter and ensures Exd explosion-proof protection. By pressing the button, you can adjust the range, characteristic curve, and electrical damping (up to 100s) within a range of 100:1. At the same time, various display units can also be selected on site. For liquid level measurement:mmH2OTheinH2OTheMmHgWait.

During system integration or loop testing, PDS's powerful simulation and online diagnostic functions can provide you with powerful assistance

HART communication makes operation easy

You can use the HART communication protocol and adjust all parameters using a PC or laptop, handheld communicator, or any HART compatible process control system. This means that the measured values and transmitter parameters are transparent at any point in the signal circuit. Using process equipment management software (PDM) based on well-known Windows operations can save a lot of time regardless of user experience.

PROFIBUS-PA Full Digital Communication

Users can use PROFIBUS-PA and Profile 3.0 for digital communication even in dangerous areas. The PROFIBUS-PA device can control three measurement tasks: flow rate (in meters)3/H, etc.), liquid level (unit:Cm, etc.)And pressure (unit: bar)）An additional electronic current limiter can prevent bus interruption in the event of a fault (fault current>3mA).

It can also establish connections between PDS and various FCS process control systems. In this case, the Process Equipment Manager (PDM) software can serve as a medium to facilitate easy installation and operation.

widely used

This transformer gas has intrinsic safety and explosion-proof functions, and can be used in explosive hazardous areas (Zone 1). The product has passed the Chinese NEPSI certification, and its measuring unit and individual components have CE testing certification, meeting the European Community CENELEC standards. Remote transmitters of different design types can be used for special applications, such as measuring high viscosity, high temperature and other media. The overload test standard for differential pressure transmitters is 63MPa, and the pressure transmitter is 6 times its range. Due to its high mechanical integrity, measuring elements with a rated overload of 42MPa can withstand a pressure of 100MPa, in other words, they will not actually be damaged at all.

Materials suitable for various applications

Even when measuring extremely corrosive substances, you can find a suitable solution in the PDS smart transmitter. For transmitters that are subjected to extremely corrosive media, the isolation diaphragm is made of stainless steel, Hastelloy, tantalum, Monel alloy, or gold. Special stainless steel can also be selected for the chamber, and the strength of PDS will be”Unbreakable.
