Versa-Switch - Model VS5100 -Premium Flow/Level/Temperature Switch
Simple field adjustable thermal differential switch for mass flow, level, and/or temperature of liquids or gasses with time delay adjustable from 0 to 300 sec. Wide operating temperature range -100°F to +850°F (-70°C to +458°C). User configurable operating power 110VAC, 220VAC, or 24VDC. Removable, plug in electronics. Can be configured with 2 independent outputs, such as level or mass flow with temperature or two mass flow rates. Level response time of .1 to 1 second on wetting, media dependent Flow response time of .5 to 10 seconds, media dependent Can be used for either gas or liquid applications including interface detection. Self heating sensor design improves repeatability. No separate heater to fail or slow response time. Two Year Workmanship Warranty
