Transmetteur de pression Danfoss 084G2211 série EMP

Product Overview

The Danfoss 084G2211 (084G2211) is a high-precision pressure transmitter tailored for demanding industrial monitoring applications. As part of the EMP series, this transmitter is designed to provide stable, reliable pressure feedback in hydraulic power units, water distribution systems, and general process control loops. By delivering a consistent 4-20 mA output, the 084G2211 ensures seamless integration with PLC and DCS architectures, playing a vital role in maintaining system precision and reducing unplanned downtime in essential industrial machinery.

Technical Configuration

This transmitter utilizes a sophisticated piezoresistive sensing element that provides a typical accuracy of 0.5 percent of the full scale. The unit is housed in a robust IP65-rated enclosure, ensuring internal electronics remain shielded from particulate ingress and low-pressure liquid splashes. The pressure connection is configured as a G 3/8 male port conforming to the EN 837 standard, facilitating secure mounting in industrial-grade pressure gauges and piping systems. Electrical interfacing is performed through a Pg 13.5 terminal block, providing a secure and vibration-resistant connection point for long-term operational stability.

Technical Specifications

FAQs

Is the 084G2211 suitable for use in vibrating environments?

The EMP series is designed to handle standard industrial vibration levels. For applications with high-frequency mechanical shock, it is recommended to install the transmitter using flexible capillary lines to isolate the sensor from the vibration source.

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

The 3.6 mA threshold acts as a diagnostic indicator. If the transmitter output drops to this level, it signals to the control system that the measured pressure is below the calibrated range or that a circuit fault is present, allowing for immediate corrective action.

Does the transmitter require periodic recalibration?

The 084G2211 is factory-calibrated for high repeatability. While not strictly required for most applications, an annual verification against a calibrated reference gauge is recommended if the system is subject to high-precision regulatory requirements.

Can this unit withstand high temperature media?

The media temperature is rated up to 70 deg C. In applications involving steam or hot oil, use a cooling tower or capillary tube to ensure the temperature at the sensing element remains within this threshold to avoid signal drift.

Installation Guidelines and Safety Measures

• Electrical Connections: Observe the P(+) and N(-) polarities during wiring at the terminal block. Ensure the Pg 13.5 cable gland is tightened to the recommended torque to maintain the IP65 seal and prevent wire strain.
• Pressure Port Installation: The G 3/8 male connection (EN 837) requires a clean, flat-sealing surface. Use a compatible washer or thread sealant to prevent leaks under the maximum overload pressure of 32 bar. Avoid applying torque to the sensor housing itself during mounting; always use the wrench flat on the fitting.
• Operational Limits: To prevent electronic degradation and premature failure, do not mount the transmitter in locations where ambient temperatures exceed 70 deg C. Provide adequate clearance around the terminal block to allow for future maintenance and signal diagnostics.
