Temperature Detectors for Moving Bearings Models 4102D, J & M Overview AMOT Model 4102D & J Temperature Valves and Model 4102M Miniature Temperature Valves are ideal for use on medium and high speed engines. The valves initiate a warning or shutdown upon a sudden temperature rise in critical machine parts caused by tight, worn or out-of-round bearings, tight packing glands, cracked or broken shafts, torsional vibration, power or compressor cylinder overload, lack of lubricant flow and many other sources. The 4102M valves provide the same low cost reliability for small bearings that have been field proven by their larger counterparts (Model 4102D & J) in larger stationary bearing applications. Model 4102D & J Temperature Detector Model 6702X Spare Fuse Rod Typical applications l Accurate and reliable in engines used for gas compression, power generation, pipeline, marine and general industrial service l Monitors bearings, shafts and other moving parts for unsafe high temperature levels l Responds to increased bearing temperatures caused by: - Tight, worn or out-of-round bearings - Cracked or broken shafts - Power or compressor cylinder overload - Lack of lubrication fluid - Tight packing glands - Torsional vibration - Mis-alignment - Other sources of temperature rise Model 4102M Temperature Detector Model 7334X Spare Fuse Rod Key features and benefits l Provides early warning of problems - avoids high cost bearing failures l Use with oil, air or gas l Instant response to excessive bearing temperatures l Compact design - easy, low cost installation l Minimal maintenance - low cost of ownership

Temperature Detectors - Model 4102 AMOT Model 4102 temperature detectors are a safety device suitable for monitoring bearing temperature. A thin film of eutectic alloy (less than 0.01 cubic mm in volume) secures a spring- loaded fuse rod. When the temperature increases, the sensing end melts the alloy and the fuse rod is instantly released moving outwards. Due to their small eutectic mass, the detectors are virtually as responsive as thermocouples. Model 4102 temperature detectors do not require the impractical wiring of electrical sensors. The trip temperature will be between 79°C and...

Temperature Detectors - Model 4102 Installation Factors • Control pressure source may be clean dry air/gas (for versatile, non-hazardous locations). • Maximum pressure to IN port of the vent valve is 60 psi. • Install the vent valve above the oil level in the sump to facilitate manual re-setting. • Each sensing device should be connected to control pressure lines and piped in series ending with the master safety control/alarm component. • Must NOT be installed with the fuse rod tip • Not recommended for installation where oil may leak along the unsealed fuse rod shaft. • See Fig. 1 or Fig....
