Combining new technology with a familiar device, the Opti-Float® level detector is a revolutionary innovation in discrete level detectors. It’s made of safe, recyclable materials, is mercury and lead free and is built to last for years of service. The design of the Opti-Float® level detector is amazingly simple. Using fiber optic cable, it transmits a beam of light from an LED in a remote transceiver down to the float, where the beam makes and breaks depending on the tilt of the float. When the transceiver detects the presence or absence of light, it activates a relay in the transceiver, which can then operate other devices. Since the float does not have any electrical parts or wires, it cannot under any condition produce arcs or sparks and cannot cause an explosion, therefor making it inherently safe. For the first time, floats can be used without the admission of electricity into an explosive area. |
