Transmetteur de pression robuste série EMP 2 Danfoss 084G2107

Product Overview

The 084G2107 (084G2107) is a high-performance pressure transmitter from the renowned EMP 2 series, specifically engineered for demanding industrial and marine applications. Designed to monitor gauge (relative) pressure in systems ranging from 0 to 6 bar, this unit is a critical component for engine cooling systems, hydraulic power units, and water treatment automation. The 084G2107 is built to withstand harsh environmental conditions, offering a typical accuracy of 0.5% FS and long-term stability that minimizes maintenance cycles. Its robust terminal block connection and IP65-rated housing ensure reliable signal transmission even in high-vibration or high-moisture environments.

Technical Configuration

The 084G2107 features the EMP 2 series' signature heavy-duty design, utilizing a G 1/2 pressure connection (standard EN 228-1) with an internal G 1/4 interface for maximum mounting flexibility. Unlike flush-diaphragm models, this transmitter uses a standard pressure port optimized for clean or filtered liquids and gases. The electrical interface is managed via a Pg 13.5 terminal block, allowing for secure field wiring of the 4-20 mA output loop. To ensure precision across varying climates, the device includes an internal compensated temperature range of 0 to 70 deg C, which effectively filters out thermal-induced signal drift.

Technical Specifications

Technical FAQs

What are the wiring designations for the terminal block?

The 084G2107 uses a standard two-wire current loop configuration. Connect the positive DC supply to the P terminal (+ supply) and the return/common to the N terminal (- common).

How does the 18 bar overload pressure rating benefit my system?

The 18 bar rating provides a safety margin three times higher than the operating range (6 bar). This protects the internal sensing element from permanent damage or calibration shifts caused by sudden hydraulic surges or pressure spikes during system start-up.

Can this transmitter be used in seawater or corrosive chemical applications?

The EMP 2 series is generally built for durability; however, always verify that the wetted parts (G 1/2 stainless steel or alloy) are compatible with your specific medium. For highly corrosive acids, a chemical seal or isolated barrier may be required.

Engineering & Installation Guide

• Terminal Block Wiring: Use the Pg 13.5 cable gland to ensure a watertight seal. When stripping wires for the terminal block, ensure no stray strands are protruding, as the compact spacing within the EMP 2 housing can lead to short circuits under high-vibration conditions.

• Vibration Dampening: In marine engine or pump room installations, mount the transmitter on a bracket that is mechanically isolated from the primary vibration source. While the unit is rated for industrial use, constant high-frequency resonance can cause micro-fatigue in the internal electronics over several years of service.

• Venting and Pressure Reference: Since this is a Gauge (Relative) pressure transmitter, ensure the internal reference port (located near the electrical entry) is not blocked by paint, grease, or heavy insulation. Proper venting is required for the sensor to accurately compare process pressure against current atmospheric pressure.
