7+(1(;7*(1(5$7,212)0$*1(7,&/(9(/,1',&$7,21 OCT REED CHAIN TRANSMITTER DESCRIPTION Model OES with epoxy coated aluminum enclosure The OCT analog transmitter mounts directly to the side of the Atlas, Aurora® or Gemini chamber, providing a continuous 4–20 mA output signal proportional to liquid level. Using simple and reliable reed switches that are surface mounted to a printed circuit board, the unit offers an accuracy of ±0.50” (13 mm). Activated by the field of the float magnets, the transmitter is completely non-invasive and designed for years of maintenance free service. Each unit is manufactured with a stainless steel outer tube which encases the reed switch assembly, resistance chain, and an aluminum or stainless steel enclosure which houses the electronic module and field wiring terminations.
