Liquid Level Detector - LLD207

Liquid Level Detector - LLD207

The LLD207 is ideal for liquid level detection, and features:

• Relay contact output.
• Provide AC sensor excitation to one or two sensors.
• Inputs are transformer coupled to eliminates DC coating problems.
• Immunity to interference.
• Green LED on front indicates unit is powered.
• Trip status is indicated by red LED.
• Ultra pure water option.
• Wide range of power choices from 12Vdc to 280Vac.

Common applications include:

• Liquid level detection using conductive probes such as PR105-1
• Soil moisture monitoring using watermark soil moisture sensor SMS009.
• Tank level control (pump ON / OFF) using 2 x PR105-1 probes or 1 x PR105-3.
• Rain detection using the RD512 using the heater option and 3 �S sensitivity.
