SELF-POWERED SENSORS

SPSR-115/230

SPSR Series and Smart Laser Sensor

The unique SPSR Series of Self-Powered Sensors provide a TTL compatible pulse output
from any of three input sensors (see page 9 for details):

• A visible optical red LED light source (ROS-P)

• An infrared light source (IRS-P)

• An amplified magnetic sensor (MT-190P)

See Page 9 for detailed sensor specifications

The TTL compatible pulse output is switch selectable as either positive going 0-5V pulses or
negative going 5-0V pulses provided on a BNC connector. Internal rechargeable batteries
provide 40 hours of operation between charges. For continuous operation, all SPSR
configurations can be powered by 115Vac, 230Vac or 9-15Vdc.

Common Applications:

• Vibration Studies

• Fans/Blades

• Engines/Motors

• Balancers

• Tach Input

• Data Acquisition

Self-powered sensors are a critical element for providing one pulse per revolution for
vibration analyzers, spectrum analyzers, stroboscopes, data acquisition equipment,
tachometers, balancers, waveform analyzers and magnetic tape recorders.
