NQ-1000 Ultrasonic Level Switch
Brand: KOBOLD Instruments, IncThe KOBOLD ultrasonic level switch NQ-1000 is a small and compact level sensor for service in vessels and piping for monitoring liquids.
The instrument monitors almost all homogeneous liquids regardless of viscosity, density and conductance.
Service in technological plants, where hitherto float switches have been used, but also in plants where only very little installation space is available (Immersion length 35 mm).
Features- Very short sensor (only 35 mm from end of thread)
- Freedom from interference by means of low-frequency oscillations
- Compact Design
- 2- or 3-wire connection
- No moving parts
- Cab be installed in any position
- Insensitive to viscosity
- Indication of output state
- Selector switch, lower/upper limiter
- High temperature, 125° C
- Pressure up to 20 bar
- Protection IP 67
