SIL - Safety Integrity Level

A SIL rating defines the measurement of performance required or level of risk reduction provided by a safety instrument function (SIF).  Many level switches can be used as part of a safety system, SIL rated vibrating switches can use self monitoring capabilities to give a high level of protection.

Vibrating Switches

Vibrating switches are used for point level measurement for liquids and granular or powdery solids.  Vibrating switches can be rod style or tuning forks and are used widely as an overfill protection device or a low level indicator.


Self-monitoring capabilities make this switch well suited to Safety Integrated Level (SIL) applications where customers need to meet the highest industry standards.

  • Unaffected by changing media
  • Self-monitoring options
  • SIL rated options
  • Used for solids and liquids
  • Suitable for turbulent, foaming and vibration
  • Available with alarm panels for complete system

Train level measurement, gauges and indicators

To solve a specific problem with access and the lack of height between a fuel tank and the trains body, AMS have modified the head of our approved level sensors to allow fitting in confined spaces. This development also removed the need for the transmitter to be located in a separate box on the side of the tank and allowed the sensor to be wired directly to the indicators, saving significant additional costs in materials and wiring time.

Train level measurement and control

Advances in the way instrumentation can be powered due to processing capabilities at reduced power levels, combined with the ever-continuing miniaturisation of electronics capability, has created the opportunity for rail companies to consider more modern electronic/digital technology as an alternative to the traditional methods for level measurement.
