NID-1100 Rotor Speed Simulator

NID-1100 Rotor Speed Simulator is a battery operated, handheld instrument which is used to electronically simulate outputs from various types of RPM sensors and transmitters in the range from 1.0 RPM to 60,000 RPM.

NID-1100 uses a menu-driven, 1.8″ TFT display (160×128 pixel, 18-bit colors) to establish appropriate settings. The key panel contains five sealed switches: Up Arrow, Down Arrow, E (Enter), Run/Stop and On/Off. The operating modes are: Manual and Automatic.

In Manual mode, the user can select the desired RPM value and the type of Output. Using Start/Stop key, the user can Start or Stop the output generation. During the generation of RPM output, the user can continually (On-line) increase or decrease the RPM value using Up or Down arrow.

In Automatic Mode, the user can select the nominal RPM, desired acceleration time (for RPM from zero to nominal), steady state time for nominal RPM and deceleration time (for RPM from nominal to zero), in range from 1.0 sec to 999.0 sec. Using Start/Stop key, the user can Start or Stop the programed output generation.

The user can select the Output signal from the following: RPM Tachometer Output (TTL Level), RPM Proximity Probe Output (powered by +24VDC), RPM Proximity Probe Output (powered by -24VDC), RPM OSO® Output.

Electric connection with DUT (Device Under Test) is established over the front mounted LEMO (ODU) Connector. Optical connection with DUT is established over the OSO (Optical Speed Output) front mounted LED.
