PARTICULATE MEASUREMENT MONITORS envea The VIEW Ex Series monitors are used to quantify particulate loadings in mg/ m3 and/or detect process upsets in bagfilters or cyclones FEATURES AND BENEFITS ■ Category 1 certified for Ex (ATEX and IECEx) Gas Zones 0, 1 & 2 and Dust Zones 20, 21 & 22 ■ Intrinsically safe dust sensor with separate advanced control unit and isolating spur (fail-safe system) ■ Unique ElectroDynamic® dust measurement principle provides robust operation ■ High-temperature and high-pressure sensor versions available (VIEW Ex 820) ■ Automatic electronic zero and drift checks -improves measurement reliability and ensures that the instrument is working correctly ■ Sufficient dynamic range is provided for "on-line" and "off-line" bag-cleaning cycles for predictive filter failure and faulty bag location detection.

Elevating standards. For life. VIEW 800/820 PARTICULATE MEASUREMENT MONITORS Ex 800 / Ex 820 Sensor Specifications and Options A The probe does not generate heat, therefore, the surface temperature is dependent upon the stack temperature, which is maximal 250°C for the VIEW Ex 800 and maximal 400°C or 450°C, respectively, for the VIEW Ex 820. B Note that the barg values given for Tamb (ambient temperature) are maximum values (Pmax). C The probe does not generate heat, therefore, the surface temperature is dependent upon the stack temperature, which is maximal 250°C for the VIEW Ex 800 and maximal...
