The EnDaL curve is an extremely versatile and modifiable data logger with sensors to measure and record mechanical shocks, temperature and humidity over an extended period of time.
Additional sensors can be connected for combined measurement of air pressure, stack pressure, inclination and up to 4 digital signals. In addition, acceleration-time graphs are recorded for up to 20 peak acceleration events.
The frequencies and the power spectral density of these graphs can be analyzed using external programs. All data can be transfered to a PC via an RS-232 interface or an USB-RS-232 port. It is possible to add a special GPS receiver.
He records position coordinates of any event and the is included in the delivery.
