Technical Explanation SENSOR TECHNOLOGIES Technical Explanation What is a pressure transmitter? In silicon-on-sapphire technology, the substrate of the thin film measuring cell is synthetic sapphire. This has excellent mechanical and temperature-stable properties, and prevents undesired parasitic effects, thereby having a positive effect on accuracy and stability. When combined with a titanium membrane, the result is a unique coaction between the temperature coefficients of sapphire and titanium. This is because, unlike silicon and high-grade steel, they are more closely matched and so only require...

Standard Signals Output signals 4-20 mA, 0-5 V and 0-10 V in particular are established in the industry. Unamplified millivolt (mV) output signals are available for some variants. Also offered are transmitters with digital USB output or customer-specific output signals (such as 1-5 V). Output Configuration v The output configuration for a 4-20 mA signal is a 2 wire connection. For 0-5 V and 0-10 V signals, the configuration is either 3 wire or 4 wire connection depending on the model variant. All mV outputs are 4 wire. Load / Apparent Ohmic Resistance for Pressure Transmitters bearing on the...

Ex Certification ATEX & IECEX Our Ex Certification ESI technology has an extensive range of intrinsically safe pressure transmitters, all ATEX and IECEx approved for explosion protection for flammable gases (zone 0), dusts (zone 20) and mining areas (group M1) II 1 G Ex ia IIC T4 Ga

Putting safety first in explosive environments….. to occur during normal operations or will exist for only a brief period of time. Our range of Ex certified pressure transmitters have both ATEX and IECEx approval. ATEX is an EU Directive (2014/34/EU) that ensures products are safe to use in explosive environments. The IECEx scheme certifies worldwide conformity to international standards and provides assurance that equipment for use in explosive atmospheres are manufactured and operated according to the highest International Standards of safety. The most common protection method for process instrumentation...

DNV GL APPROVAL FOR MARINE APPLICATIONS ESI marine products have DNV GL classification for ships, high speed & light craft and DNV GL offshore standards. It is becoming increasingly important that the components and equipment used in the marine industry are tested and certified as suitable for use in harsh environments. ESI Technology have recognised the demand, and have classified a range of products from vacuum to 5000 bar, which cover most eventualities in the Marine workspace. DNV GL approval confirms that ESI Technology pressure sensors are compliant to their manufacturing rules, and have...
