FCI's first and most widely used level/interface switch monitor, the 8-66B BASIC insertion type level and interface switch provides 0.25 inch [6 mm] control of liquid level or product interface. Any type of external control system can be actuated from either the normally open or closed output contacts of the instrument's on-board DPDT relay.
The level/interface sensing element of the instrument and its modular control circuit are mounted in a rugged aluminum enclosure that is Factory Mutual, CSA, CENELEC and CE Mark approved for hazardous location service.
The wetted surfaces of the sensing element are 316 stainless steel with nickel-braze providing resistance to most liquid, gaseous and particulate media.
