Level Transmitter Attains European Type Approval on Steam Drums
Jan 28 2009
The Eclipse 705 combines two major advantages against the traditionally used transmitters; high reliability â repeatability and an efficient process seal. The Eclipse uses the technology of Guided Wave Radar. This measuring principle measures independently of the process parameters such as density, conductivity, dielectrics, pH, etc. High pressure and temperature changes inside a boiler have an important impact on the accuracy and reliability of the traditional transmitters such as differential pressure, displacer and RF capacitance. The process seal of the 7MS probe is specifically designed for use on saturated steam. The dynamics of the seal take the sudden and aggressive changes of process pressure and temperature into account.
The Eclipse 705 with 7MS probe resists a process pressure of 155 bar at an equivalent temperature of +345Â°C in saturated steam applications. For non-steam applications, Eclipse can be used on process conditions from â196Â°C up to +430Â°C / full vacuum up to 430 bar. The Eclipse 705 transmitter can be configured for both measuring level and liquid-liquid interface in level units or volume units.
The Eclipse 705 is also available with a SIL2 version. The additional diagnostic tools allows the user to integrate this transmitter with high demanding safety instrument loops. With a SFF (Safe Failure Fraction) of 91%, Eclipse is the only TDR transmitter on the market that scores as high on safety level. The Eclipse 705 (with enhanced SIL electronics) is suitable for SIL2 loops as 1oo1 device (hardware fault tolerance 0 â FMEDA analyzed by Exida per IEC 61508).
The Eclipse 705 disposes of FieldbusÂ®, AMSÂ® ,HartÂ®, FDTÂ®/PACTwareÂ® communication.
