Protection Monitors
Sensonics displacement monitoring sensor systems offer a range of both contact and non-contact techniques for accurate measurement of relative and differential expansion on critical machines and infrastructure. Our range of LVDT devices offer contact displacement monitoring measurements from a few mm's up to 600mm; designed for extreme environments they offer excellent linearity in combination with a high thermal stability.
Our range of non-contact eddy current proximity probes offer both displacement and vibration measurements through eddy currents set up in the surface of the target material - shaft, collar, etc. Compliant with the API670 standard, these displacement monitoring systems are supplied tuned to a fixed length consisting of probe (diameter determines range), extension cable (if required) and driver.
These sensors combined with our established displacement monitoring and protection equipment offer high integrity measurements with flexible alarm facilities, backed up with over 30 years field experience.

Sentry API670 Monitoring and Protection System
The Sensonics API670 compliant Sentry range of rack mounted equipment has been developed to provide a one-stop shop for all your measurement requirements. A range of units are available offering thrust, differential expansion, case expansion and valve position measurement regimes. The Sentry monitoring system is particularly suitable for large turbine generator sets where the displacement monitoring forms part of the essential Turbine Supervisory System. Intuitive commissioning software allows the user to calibrate the displacement monitoring system with ease.

Aegis Monitoring and Protection System
The Aegis system offers similar measurement capabilities to Sentry but in a lower cost rack mounted package. A range of units are available offering thrust, case expansion and valve position measurement regimes. The system utilises a shared display located in the instrument rack with single channel cards for each of the required measurement channels. The Aegis monitoring system is suitable for a range of rotating machinery including turbines, motors and pumps where individual channel displays are not required (closed equipment cabinets, unmanned sites, etc). Other measurement modules include vibration, temperature and speed in addition to the displacement monitoring options. This technology is also available as a single channel unit (MO9601) in a wall mounted enclosure for standalone applications.

DN2603 Thrust Monitoring and Protection unit
The DN2603 is a DIN rail mountable thrust monitor compatible with a range of eddy current proximity probes to suite most thrust monitoring applications. This compact single channel unit offers dual level alarms (positive and negative going) in combination with 4-20mA outputs for PLC or DCS connection. Both offset and slope can be adjusted in situ to enable correct calibration of the displacement monitoring system. Other measurement modules in the DN 26 range include vibration, temperature and speed.
