Fail Safe Mechanical Speed Sensor
95004
The Fail-Safe rotary speed control is a fluid/magnet actuated mechanical switch. It incorporates the consistent and dependable forces of gravitation and magnetism to achieve its mechanical switching action. Because the unit requires no electrical power to operate, it can be used in remote areas where access to power supply is inconvenient or unavailable.
