1. Application The Ex-MX2 is a contactless temperature measuring device designed for industrial use in potentially explosive areas of Zones 2 and 1 in accordance with Directive 1999/92/ EC (ATEX 137). 2. Safety instructions These operating instructions contain information and safety regulations that must be followed to ensure safe and reliable operation of the unit under the described conditions.
During use, always make sure that the leather pouch is completely closed and undamaged. - Only accessories approved by ecom instruments GmbH may be used. - Avoid using the unit in aggressive acidic or alkaline solutions. - Ensure that the unit is not taken into Zone 0 areas. 4.1 Special conditions for use in Zone 0 areas Temperature measurement with the Ex-MX2 is only allowed within Zone 0 only if the following conditions are met: 1.
60:1 at the focus point (1.15 m) and Measuring spot size (distance / Ø): 35:1 in the far field (> 10 m) Accuracy (25 °C): ± 0.75% of the measured value or ± 0.75K, whichever is the larger value (± 2K for measurement objects below -5°C) Ambient derating (at 25 °C ± 25K): <0.05K/K or <0.05%/K, whichever is the larger value Reproducibility: ± 0.5% of the measured value or ± 0.5K, whichever is the larger value Spectral sensitivity: 8 ...
8. Functional description / operating information Please take the time to carefully read through these operating instructions to ensure that you are familiar with and can use all the functions on your Ex-MX2. For your own safety and information please read through the information on the following pages. 8.1 Operation All objects with a temperature above absolute zero radiate infrared energy which spreads in all directions at the speed of light.
8.3 Display screen Continuous measurement Laser Maximum setting reached Measured temperature Bar display of the last 10 measured values Battery condition Emissivity MIN/MAX display of the last measurement 8.4 Settings System settings can be fixed and activated with the switch panel.
.4.1 Emissivity Most organic materials and lacquered and oxidised surfaces have an emissivity of 0.95. The emissivity is preset to 0.95 in the Ex-MX2 for this reason, but can be changed with the rocker switch. The determination of the temperatures of shiny or highly polished metal surfaces produces inaccurate measured values. To compensate for this, the surface to be measured can be covered with adhesive tape or painted matt black.
8.5.2 Optical diagram Ø mm measuring spot Distance m 25 0 19 1.15 29 1.50 58 2.50 72 3.00 8.5.3 Field of view Ensure that the measuring object is larger than the size of the measuring spot of the device. The smaller the measuring object the closer you must approach the object. If the measurement accuracy is crucially important, the measuring object should be at least twice as large as the size of the measuring spot. 9.
