The LIQUID LEVEL DETECTOR BLLD207 offers an economic solution to applications requiring an isolated liquid level or soil moisture detection. Due to its total width of only 23.5mm and the 35mm DIN-Rail mounting arrangement the BLLD207 is ideal for field enclosures or as a “space saver” in larger control cabinets. Its transformer coupled input eliminates DC coating problems and low energy immunity to interference. A precision oscillator and amplifier drives the input transformer, when conduction occurs the detector relay trips. Front LED’s indicate power trip condition. Power choices vary from 12Vdc to 280Vac. Double surge protection is standard as with all series 200 modules to prevent failure due to spikes induced by DC switched inductive loads.
➢ Liquid level detection using conductive probes from BASI
➢ Soil moisture monitoring using watermark soil moisture sensor SMS009.
➢ Tank level control (pump ON / OFF) using 2 x conductive probes
➢ Rain detection using the BRD512 using the heater option and 3 μS sensitivity.
