Danfoss EMP 2 Precision Pressure Transmitter 084G2109 4-20mA

Product Specification

Original Danfoss Precision Pressure Transmitter EMP 2 (Model: 084G2109)

Product Introduction

The Original Danfoss EMP 2 is a high-precision pressure transmitter designed for monitoring and control in marine and industrial applications, delivering reliable pressure measurements even under harsh environmental conditions. Part of Danfoss’ flexible pressure transmitter lineup, it offers absolute or gauge (relative) pressure versions with zero and span adjustment, and a 4–20 mA output signal. Certified with all necessary marine approvals, it is suitable for demanding scenarios such as offshore platforms, industrial machinery, and hydraulic systems. Special versions with an integrated pulse-snubber are available to handle severe medium influences like cavitation, liquid hammer, or pressure peaks, making it versatile for media including water, fuel, oil, lubricants, refrigerants, natural gas, and more. With robust construction and compliance with industry standards (e.g., EN 60770, EN 61000), it ensures stability and accuracy in diverse operating conditions.

Features

High Precision Measurement: Boasts excellent accuracy, with low zero and full-scale thermal drift (<0.06% of full scale/°C) and minimal voltage dependence (<0.1% of full scale/10V), ensuring reliable data in varying environments.

Wide Operating Range:

Temperature range: -10 to 70°C (operating); -50 to 85°C (transportation/storage).

Measuring range: 0 - 400 bar, with flexibility for vacuum (below zero bar) applications.

Flexible Pressure Connections: Standard connections include G ¼, G ½A, and G 3/8 A (for pressure gauges), facilitating easy integration into different systems.

Adjustable Settings: Features zero adjustment (-5 to 20% of range) and span adjustment (5% of range), with combined zero and full-range adjustment for precise calibration.

Explosion Protection: Suitable for Normal ATEX Zone 2, ensuring safety in hazardous areas with potentially explosive atmospheres.

Marine Compliance: Holds all relevant marine approvals, meeting classification society requirements (e.g., withstanding 4g acceleration up to 100 Hz), making it ideal for maritime applications.

Robust Construction: Enclosure with IP67 rating (porcelain-enameled die-cast lattice) provides protection against dust and water ingress. Resistant to vibration (4g acceleration at 3-300 Hz) and shock (500g for 1 ms), ensuring durability in harsh conditions.

Pulse-Snubber Option: Special versions with integrated pulse-snubber handle cavitation, liquid hammer, and pressure peaks, with a response time <35 ms for such variants.

Broad Media Compatibility: Compatible with diverse media including water, fuel, oil, lubricants, refrigerants, chlorine, and natural gas, adapting to industrial and marine fluid systems.

Electrical Reliability: Operates on 12–32 VDC power supply, with load resistance up to 410 Ω (24 VDC) for standard settings. Complies with EN 61000-6-2/3 for noise immunity, resisting high-frequency interference, electrostatic discharge, and voltage transients.

Compact Design: Lightweight (approximately 1 kg) with a cable diameter of 5–14 mm, facilitating easy installation in space-constrained environments.
