Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 
The devices are pressure and temperature operated switches, with a solid-state switch mechanism, an LCD (Liquid Crystal Display), a flameproof enclosure and may contain solid-state analog outputs. The metal enclosure consists of a base and a cover with a glass window, as well as two conduit entries and a sensor port. The cover is secured to the base by a threaded joint. The window is cemented into the cover and additionally secured by a retaining ring that threads into the cover. The sensors engage the base of the enclosure by a threaded joint. The devices are provided with terminal blocks for field installation.

The 1XSWLL Model is the only model to have “d”, “ia”, “tb” and “nA” approvals.
