This makes the system suitable for a range of moisture measurement applications in hazardous areas where explosion-proof certification is needed, in addition to the existing intrinsically safe options.
The ES20 system was designed to offer several standard configurations suited to typical industrial and gas process applications, such as monitoring moisture in compressed air or natural gas. These standard configurations enable short lead times and fast delivery of orders.
Sample conditioning is vital when monitoring moisture levels in gas, not only to ensure that the pressure and temperature of the sample gas is consistent, but also to prolong the life of the sensor by removing contaminants such as dust or molecules of oil. The ES20 Compact Sampling System offers a choice of particulate or coalescing filters with a maximum pressure of 20 barg. Three mounting options are also offered to suit various indoor or outdoor locations: the system can be either mounted on a base plate, within a GRP enclosure or with a stainless steel enclosure, to provide IP66/NEMA 4X protection.
The ES20 modular systems are compatible with other Michell products, and are designed around the Michell Easidew range. These dew-point transmitters provide accuracy of ±2°Cdp, with a wide measurement capability of -100 to +20°C dew point, and are available with Michell’s unique sensor exchange programme. With the sensor exchange programme, customers are able to order a freshly calibrated sensor to fit in to their system and, when this arrives, replace their old sensor and return it to Michell. This enables them to keep their sensor calibration up to date, with minimal shut-down.
