 The Endevco Model 50 and 50M1 are small Piezoelectric
Accelerometers with integral amplifiers, developed specifically
for modal measurements or OEM vibration applications.
In addition to having minimum unit-to-unit phase deviations,
the built-in microcircuit has been configured to work
in a constant current mode with a supply voltage as low
as +12 VDC, as with a care battery. The units are designed
to be mounted with our adhesive or integral high strength
magnet (50M1). A dielectric layer on the base isolates
the case ground from the mounting surface to eliminate
the potential ground loops. These accelerometers are hermetically
sealed to provide long-term reliability even in harsh
environments, and their light weight (3.8 gm) effectively
minimizes mass loading effects. The inside of the protective
vinyl cap can be filled with RTV to further improve resistance
to moisture at the connection junction.
For your convenience, the Model 50 and 50M1 come with
a 3-meter pair of output wires attached, ready to be used
right out of the box. A matching low-cost, 10-channel
power supply (Model 4475) is also available. Other Endevco
ISOTRON® Signal Conditioners, such as Model 133, 2792B,
2793 or 4416B can also be used with this unit.
Features:
• Low-cost vibration sensor
• Light weight (3.8 gm)
• Milli-g's resolution
• Easily mounted
• Ideal for R&D; lab tests or full-scale modal testing
