GENERAL DESCRIPTION
NQ is a compact, ultrasonic level switch which activates when immersed in liquid. Its short intrusion length (1.42”) makes it the right choice for applications in which container size is limited.
The NQ may be installed either as two or three wire controller. Voltages ranging from 24 to 240 VAC/VDC, 50/60 Hz may be controlled in the two wire configuration. Glass fibre reinforced nylon and 316 SS construction (in a NEMA 4X housing, of course!) make the NQ a tough performer in industrial applications. Extended probe lengths are available.
