    Product Description Operation principle The Rosemount 2130 level switch consists of a tuned fork with a driver and receiver element, and integral interface electronics. The 2130 level switch is based on the principle that the resonant frequency of a tuned fork changes when it is immersed in a liquid. The frequency change is detected and used to switch an electronic output.

  • Page 19: 6Appendix A: Specifications

    Based on general field failure data and manufactures component data, a useful life period of approximately 18 years is expected for the Rosemount 2130 level switch at an ambient temperature of 55 °C. This decreases by a factor of two for every increase of 10 °C, and increases by a factor of two for every decrease of 10 °C.

  • Page 20: Useful Lifetime

    It is the responsibility of the end-user to maintain and operate the Rosemount 2130 level switch according to the manufacturer's instructions. Furthermore, regular inspection should show that all components are clean and free from damage.
