330450 High-Temperature Acceleration Sensor (HTAS)
The 330450 HTAS segregates the sensing element from the signal conditioning electronics, with the two permanently connected via a hard-line cable. This allows the sensing head to be mounted on surfaces with temperatures as high as +400°C (+752°F), while the signal conditioning electronics can be installed in a cooler location.
Parameters are specified from +20 to +30°C (+68 to +86°F) and 100Hz unless otherwise indicated.
Note: Operation outside the specified limits may result in false readings or loss of machine monitoring.
