Cảm biến đo độ rung đo nhiệt độ SKF CMSS 797T-1

Superior sensor, ring mode, side exit, acceleration and temperature

The CMSS 797T-1 is a higher precision accelerometer that also offers an in-built measurement of the temperature of the mounting point surface The sensor is most applicable in the following industries:

• Power Generation (Fossil, Nuclear, Hydro) – pumps and fans, where regulatory expectations may require a higher vibration precision

The surface temperature measurement is good for rolling element (anti-friction) bearing housings and small journal bearing housings Temperature measurements in large journal bearings should use established measurement locations.

Features

• Optimal for use with SKF on-line surveillance systems, protection
systems and all portable data collection instruments
• Measures both temperature and acceleration
• Rugged construction
• Hermetically sealed
• Case isolated
• Meets CE, EMC requirements
• ESD protection
• Reverse wiring protection
