Transmetteur de pression industriel EMP 2 10 bar Danfoss 084G2110

Product Overview

The 084G2110 (084G2110) is a high-performance EMP 2 series industrial pressure transmitter engineered by Danfoss for demanding marine and land-based applications. Designed to monitor gauge (relative) pressure from 0 to 10 bar (0 to 145.04 psi), this transmitter converts mechanical pressure into a stable 4-20 mA current signal. The 084G2110 is built to withstand extreme industrial conditions, featuring a massive 60 bar overload pressure rating and a robust IP65-rated terminal block enclosure. Its high accuracy (0.5% typical) and fast 4 ms response time make it an ideal choice for hydraulic control systems, water processing, and engine room monitoring where reliability and signal integrity are non-negotiable.

Technical Configuration

The 084G2110 utilizes a ruggedized sensor architecture designed for longevity and precision:

• EMP 2 Series Specialization: Engineered for heavy-duty environments, including marine applications, with a design that excels in high-vibration and high-pressure-spike scenarios.

• Gauge Pressure Reference: Measures pressure relative to atmospheric pressure, ensuring accurate readings for open-loop fluid and gas systems.

• Clipping Level Safety: Features advanced signal management with low (3.6 mA) and high (22.4 mA) clipping levels, allowing control systems to easily differentiate between standard operation and sensor faults.

• Versatile Mechanical Interface: Equipped with a G 1/4 external and 1/2 inch internal pressure connection according to EN 228-1, facilitating easy installation into various piping manifolds.

Technical FAQs

How does the high overload pressure rating benefit the system?

The 084G2110 features a 60 bar overload rating, which is six times its maximum operating range. This provides an exceptional safety margin against "water hammer" or hydraulic spikes that would typically destroy standard transmitters, significantly reducing long-term maintenance costs.

What is the significance of the signal clipping levels?

The low clipping (3.6 mA) and high clipping (22.4 mA) levels allow your PLC or DCS to detect hardware failures. A signal falling below 3.6 mA usually indicates a wire break or sensor failure, while a signal above 22.4 mA indicates a short circuit or extreme overpressure, enabling immediate safety shutdowns.

Can this transmitter be used with seawater or corrosive media?

While the EMP 2 series is robust, the compatibility depends on the wetted parts material. For 084G2110, the pressure connection is G-type threaded. In seawater applications, ensure the use of a chemical seal or verify that the internal diaphragm material is rated for the specific corrosive agent.

Engineering & Installation Guide

• Wiring for Signal Integrity: The transmitter uses a 2-wire 4-20 mA loop (P = Positive supply, N = Common/Negative). Use twisted-pair shielded cable for all connections to prevent electromagnetic interference (EMI) from high-power equipment like VFDs or motors from distorting the 0.5% accuracy.

• Terminal Block Sealing: To maintain the IP65 rating, the Pg 13.5 cable gland must be tightened securely around the cable jacket. Ensure the terminal block cover is properly seated with its gasket before tightening the housing screws to prevent moisture ingress in humid or wash-down environments.

• Pressure Snubbing: Although the unit has a 60 bar overload rating, installing a pressure snubber is recommended if the transmitter is placed near a high-speed solenoid valve or a positive displacement pump. This helps dissipate the kinetic energy of fluid pulses, extending the life of the sensing element.
