Transmetteur de pression Danfoss 084G2111 Série EMP

Product Overview

The Danfoss 084G2111 (084G2111) is a high-performance pressure transmitter engineered for stable and reliable monitoring in demanding industrial process control loops. As part of the EMP series, this transmitter excels in providing precise feedback for hydraulic systems, water treatment infrastructure, and general industrial machinery, playing a vital role in maintaining system integrity and reducing costly unplanned downtime. The device provides a stable 4-20 mA output, ensuring compatibility with modern PLC and DCS architectures.

Technical Configuration

This transmitter features a ruggedized architecture designed for longevity in industrial environments. It utilizes a reliable piezoresistive sensing element that delivers a typical accuracy of 0.5 percent of the full scale. The unit is housed in an IP65-rated enclosure, providing protection against particulate ingress and low-pressure water streams. Electrical interfacing is managed via a standard Pg 13.5 terminal block, which ensures secure, vibration-resistant connections for long-term operational stability. The pressure connection is configured as a G1/2 male/female combination, facilitating versatile integration into standardized EN 228-1 fluid piping systems.

Technical Specifications

FAQs

Is the 084G2111 suitable for high-vibration machinery?

Yes, the EMP series is designed to withstand typical industrial vibration profiles. However, for applications with extreme mechanical shock or high-frequency vibration, ensure the transmitter is mounted using vibration-dampening fittings.

What is the function of the low clipping level at 3.6 mA?

The 3.6 mA low clipping level serves as an under-range diagnostic indicator. If the transmitter output falls to this value, it indicates that the sensed pressure has dropped below the lower operational limit or that a short-circuit fault exists in the sensing element.

Does this transmitter require external calibration?

The 084G2111 is factory-calibrated for high precision. Regular field calibration is generally not required unless the application demands strict adherence to specific regulatory standards or if the device has been subjected to significant mechanical stress.

Can this unit be used in steam applications?

The media temperature range is limited to 70 deg C. If used in steam applications, you must use a cooling coil or capillary tube to ensure the media temperature at the transmitter diaphragm does not exceed this threshold.

Installation Guidelines and Safety Measures

• Electrical Connections: When wiring the terminal block, ensure the P(+) and N(-) polarities are strictly observed to avoid internal damage to the transmitter electronics. Use PG 13.5 cable glands and ensure they are tightened sufficiently to maintain the IP65 seal against humidity.
• Pressure Port Compatibility: The device features a dual G1/2 male/female connection (EN 228-1). Ensure the mating thread is clean and free of debris. Use an appropriate sealing washer or liquid thread sealant compatible with the process media to prevent leaks under the maximum overload pressure of 32 bar.
• Operational Environment: Avoid mounting the transmitter in areas where the ambient temperature exceeds 70 deg C, as this will lead to premature electronic failure and signal drift. Ensure the installation location provides adequate clearance for field maintenance and wiring access.
