K7L

Сверхминиатюрный усилитель датчика утечки жидкости

Доступна монтажная колодка с безвинтовыми клеммами типа «Push-in plus» (P2RF-08-PU) для удобного подключения проводов. K7L обнаруживает утечку широкого спектра жидкостей, от воды до жидких химикатов с низкой электропроводностью.

Рабочий диапазон: до 50 MΩ.
Четыре диапазона измерения.
Способ обнаружения: измерение проводимости.
Два индикаторных светодиода: зеленый — индикация включения питания, красный — индикация срабатывания реле.
Соответствует Директиве по ЭМС и Директиве по низковольтному напряжению, имеет сертификаты UL/CSA.
