Description
Global Water® WL400 Water Level Sensor, 50 ft. Cable, 0 to 30 ft. Sensor Range, AIC050Features:
- High accuracy and reliability
- Pressure transducer and cable completely submersible
- Easy installation due to compact, rugged design
- Low maintenance requirements
- Compatible with most monitoring equipment — adaptable to dataloggers, telemetry, displays, etc.
- 4-20 mA output — signal can run up to 3,000 ft. from the sensor to the logging device
- Vented cable provides automatic barometric compensation
- Wet-wet water level sensor eliminates vent tube concerns
- Dynamic temperature compensation system enables high accuracy measurements over a wide temperature range
- Submersible solid-state pressure transducer is encapsulated in a 13/16 in. stainless steel housing and is not affected by foam, wind, or rain
- Unique, highly flexible silicon diaphragm to interface between water and sensing element protects electronics from moisture and privdes exceptional linearity and very low hysteresis which is common is sensors with metal foil diaphragms
- Monitors levels in groundwater wells, rivers, streams, tanks, lift stations, and open channels — even in severe environments
- CE certified
- Multiple level ranges from 3 ft. maximum to 500 ft. maximum are available with standard or custom length cabling (call for information)
