HOBOnet Water Level Sensor Interface

Eine drahtlose Sensorschnittstelle, die mit dem HOBOnet-System zur Fernüberwachung des Wasserstands arbeitet.

Die HOBOnet-Wasserstandssensorschnittstelle verfügt über einen vorkonfigurierten, leicht zu installierenden Funksensor, der genaue, zuverlässige Wasserstandsdaten direkt an eine HOBO RX3000- oder HOBO MicroRX-Station, die Kernkomponente des HOBOnet-Fernüberwachungssystems, überträgt.

Wichtige Informationen

Ein vollständiges System erfordert mindestens einen HOBOnet Wasserstandssensor, a Direktlesekabel, und eine HOBO RX3000 Fernüberwachungsstation und HOBOnet Drahtlos-Manager (oder ein HOBO MicroRX-Station mit einem integrierten HOBOnet Wireless Manager). HOBOnet Wireless Repeater (RXW-RPTR-xxx oder RXW-RPTR-B-xxx) können hinzugefügt werden, um die Reichweite zu erhöhen.

Water Level Sensor

See referenced below: * Water Level Accuracy: With accurate reference water level measurement, known water density, & a stable temp environment. System Water Level Accuracy equals the sum of the Barometric Water Level Accuracy plus the selected sensor end Water Level Accuracy.

** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.

***Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. Can be up to 0.5% of additional error due to rapid temperature changes. Measurement accuracy also depends on temperature response time.
