1.0 INTRODUCTION
The SPSR-IM Self Powered Sensor Interface Module
is a self-contained, rechargeable battery powered
device for developing a TTL compatible one pulse
per revolution output for triggering external
equipment such as vibration analyzers, spectrum
analyzers, stroboscopes, data acquisition equipment,
tachometers, balancers, waveform analyzers and
magnetic tape recorders.
The SPSR-115/230 is comprised of the SPSR-IM Interface Module, which
provides power to a sensor and couples the sensor to a BNC output; an input
sensor with a visible red LED light source (ROS-P); and a battery recharger.
Optional sensors such as an optical laser
sensor (ROLS-P-not shown), infrared
sensor (IRS-P), or an amplified magnetic
sensor (MT-190P) may also be combined
with the SPSR-IM Interface Module when
appropriate. (See separate instructions for these configurations.)
2.0 FUNCTIONS AND OPERATION
2.1
SPSR Interface Module
The SPSR Interface Module (SPSR-IM) provides power to the input sensor,
receives and optionally inverts the return pulse signal, and provides a
switch selectable positive going 0 to 5 V dc or negative going 5 to 0 V dc
pulse train trigger output on a BNC connector. Connections and operation
are common to all SPSR models. Fully charged internal NiMH batteries
will typically provide greater than 40 hours of continuous operation. In
addition, the SPSR system can be operated continuously on external
power by use of the recharger/power supply provided.
