Transmetteur de pression industriel EMP 2 Danfoss 084G2113

Product Overview

The 084G2113 (084G2113) is a heavy-duty EMP 2 series pressure transmitter specifically engineered by Danfoss for marine and industrial applications where reliability under extreme conditions is paramount. Delivering a precision 4 - 20 mA output signal across a 0 - 40 bar pressure range, this unit is built to withstand high-vibration environments such as engine rooms, hydraulic power units, and water processing plants. With a typical accuracy of 0.5% FS and a rapid response time of 4 ms, the 084G2113 provides the high-fidelity data required for real-time control loops and safety monitoring. Its robust "Sealed Gauge" reference ensures consistent performance by eliminating the influence of atmospheric pressure fluctuations, making it a critical asset for high-pressure system stability.

Technical Configuration

The EMP 2 platform (Specification Key: EMP 2-2631-F6CD24-2) is designed for maximum field durability. It features a unique electrical interface consisting of a terminal block housed within a Pg 13.5 cable entry, providing a more secure and vibration-resistant connection than standard plug-in types. The pressure interface is highly versatile, utilizing a G 1/2 male connection with an internal G 1/4 female thread, compliant with EN 228-1 standards. Internally, the transmitter is laser-calibrated for a compensated temperature range of 0 to 70 deg C, minimizing thermal drift. Safety and reliability are further enhanced by a high overload pressure rating of 80 bar and clipping levels (3.6 mA to 22.4 mA) that allow for advanced diagnostic detection of sensor faults or short circuits.

Technical FAQs

What is the benefit of the terminal block connection over a standard plug?

The terminal block in the 084G2113 allows for a direct, hard-wired connection that is less prone to loosening in high-vibration marine environments compared to DIN plugs. The Pg 13.5 cable gland provides a superior mechanical grip and environmental seal for the signal cable.

How do the clipping levels (3.6 / 22.4 mA) assist in system diagnostics?

These levels define the sensor's output boundaries. If the PLC detects a signal below 3.6 mA or above 22.4 mA, it can immediately identify a hardware fault (such as a broken wire or sensor failure) rather than interpreting the data as a valid pressure reading, preventing incorrect automated responses.

Does this unit require a specific mounting orientation?

While the EMP 2 is designed to be orientation-independent, it is best practice to mount it with the pressure port facing downwards in gas applications to prevent condensate accumulation, or horizontally in liquid systems to avoid air entrapment at the sensing diaphragm.

Engineering & Installation Guide

• Wiring Precision: When connecting to the internal terminal block, use ferrules on all stranded wire ends. Observe the polarity: connect the positive supply to terminal "P" and the common/signal return to terminal "N." Ensure the Pg 13.5 gland is tightened firmly to maintain the IP65 rating and protect the internal electronics from salt mist or humidity.

• Overpressure Protection: Although the unit features an 80 bar overload rating, systems prone to severe hydraulic water hammer should utilize a damping snubber. The dual-thread G 1/2 male / G 1/4 female connection allows for flexible mounting of such protection accessories directly to the transmitter.

• Thermal Considerations: Ensure the medium temperature does not exceed the 70 deg C limit. In high-temperature steam or oil applications, use a pigtail syphon or a capillary stand-off to ensure the temperature at the sensor interface remains within the compensated range of 0 to 70 deg C for maximum accuracy.
