Aplisens Smart Differential Pressure Transmitter APR-2000

Introduction – Aplisens Smart Differential Pressure Transmitter APR-2000

The Aplisens APR-2000 Smart Differential Pressure Transmitter is a high-accuracy device engineered for precise measurement of differential, level, and density pressures in gases, vapours, and liquids. Designed for modern process automation, it combines a 4…20 mA output with HART 5/7 communication for advanced integration and configuration. The transmitter is widely applied in process, chemical, and marine industries and is available in several certified safety versions.

The APR-2000 series includes an enhanced model — APR-2000ALW — which features a local digital display and HART communication interface. In Aplisens product codes, “ALW” identifies the version equipped with a display and full configuration capability via keypad and communicator, ensuring convenient on-site calibration.

Built with a fully welded silicon sensor, the transmitter guarantees long-term stability and tightness of the oil system. It carries a wide range of intrinsic safety, explosion-proof, and functional-safety approvals (SIL 2 / SIL 3). Reliable performance, local or remote configuration, and rugged housing make it ideal for demanding applications, including installations across the UAE and the wider MENA region, supplied by Dubai Sensor.

FAQ – Aplisens Smart Differential Pressure Transmitter APR-2000

Q1. What is the Aplisens APR-2000 used for?
The APR-2000 is designed to measure differential, level, and density pressures of gases, vapours, and liquids. It is ideal for hydrostatic level measurement in closed tanks and for monitoring filter loss or process pressure differences.

Q2. What is the difference between APR-2000 and APR-2000ALW?
Both models share the same core measuring technology. The APR-2000ALW version includes a local display and HART communication interface, allowing on-site configuration via keypad. The standard APR-2000 model does not include the display.

Q3. What does “ALW” mean in the model code?
“ALW” designates the version equipped with a local digital display and HART interface, offering local calibration and setup capability.

Q4. What certifications does the APR-2000 series have?
The transmitter is certified for intrinsic safety (ATEX, IECEx, FM, CSA, INMETRO, UKCA, KCS), explosion-proof (Ex d / XP), and functional safety (SIL2/SIL3). Marine certificates DNV and BV are also available.

Q5. What is the accuracy of the APR-2000 transmitter?
The device provides a ±0.1% of full-scale output (FSO) accuracy, ensuring precise differential and level measurement even in demanding industrial conditions.

Q6. What is the meaning of “Ex d” in the specification?
“Ex d” stands for Explosion-proof (Flameproof enclosure) protection. It prevents any internal ignition from spreading to the external explosive atmosphere, making it suitable for Zone 1 and Zone 2 hazardous areas.

Q7. Can the APR-2000 be configured remotely?
Yes. The transmitter can be configured using a HART communicator (e.g., Aplisens KAP-03) or RAPORT 2 software via a HART/USB converter. The ALW version also allows local configuration via display and keypad.
