EGE Elektronik Sensor Air Flow Sensors Productseries LNZ 450 WR1-K

Description

The EGE Elektronik LNZ 450 WR1-K is the authoritative choice for facilities that require airflow monitoring without a dedicated DC power supply. The “WR1” designation signifies a wide-range alternating current (AC) power capability, allowing the sensor to operate on standard industrial mains (typically 115V AC or 230V AC). Furthermore, the Relay output provides a potential-free contact, allowing it to switch AC or DC loads directly, such as alarm sirens, motor starters, or heavy-duty contactors.
