The 1-890 is a versatile multi-purpose vibration switch. It features a built-in accelerometer and solid state electronics. The 1-890 is available in a variety of ranges and enclosures. The 1-895 is a 1-890 mounted in an explosion proof enclosure.
The 1-890 constantly monitors the vibration levels on critical machinery and pro-vides timely feedback in the event of machine breakdown. There is a 30 second monitor start up delay that is initiated by the application of power or the grounding of the start input. The delay does not begin until the start input is released. The current vibration level is displayed on a 3digit LCD and output on a proportional 4-20 mA current loop. The alarm levels are set by two front panel push-buttons
and the display. Two alarm indicators are present and indicate when an alarm level is exceeded.
The corresponding output is also enabled. The alarms are latched and must be reset at the 1-890 or via a remote alarm reset input.
