Technology of the OCT-400
Analog Transmitter
The OCT-400 analog transmitter mounts directly to the side of the MLI chamber, providing a continuous 4-20 mA output signal proportional to liquid level. Using simple and reliable reed switches surface mounted to a printed circuit board, the unit provides level accuracy of ±0.50" (13 mm). Activated by the field of the float magnets, the transmitter is totally 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, and an aluminum or stainless steel enclosure which provides signal/power field wiring terminations. |
