The StorageWorks SAN Switch 2/8-EL by Compaq is the next generation entry-level SAN Switch featuring 2Gb transfer speed and the optional ability to trunk or aggregate the throughput of up to four ports. With eight ports users will be able to create up to two 8Gb trunked ISLs between two or more similar 2Gb switches. It also features the SFP (small form factor pluggable) connectors which allow for higher port density than was available using GBICs. The higher speed coupled with the optional Trunking feature will allow users to install these switches in pairs for use as high speed backbone devices for joining SAN islands with little to no performance degradation.

Field adjustable liquid level differential range: 1", 2", 3"& 5"
Large differential provides immunity to nuisance switch tripping due to severe wave action and turbulence, low cost, single point pump up/down level control
Glass filled Noryl or Celanese Fortron PPS engineering plastic, 316 SS, Hastelloy "C", C/EPOXY. 250 PSI, 200°F, 15 to 115 amp to 240 VAC/DC/SPDT power switch, & SPDT dry circuit contacts. The ULS-1 Series Ultrasonic Level Switches are low cost, compact, level sensors with no moving parts, these small units are ideal for a variety of point level sensing applications especially where dependability and economy are a must. It's small size, easy installation and suitable for application in liquid with mixed materials or slurries.
The enclosure is made in PC that can resist oil
And acid / corrosion. Several switches can be used at the same time won't be interrupted by each other. It can be hooked up relay and PLC for application.
