The unique SPSR (Self Powered Sensor) with internal rechargeable batteries provides the required power to any one of (4) Monarch Sensors (see below). The TTL compatible output is switch selectable as either positive going 0-5V pulses or negative going 5-0V pulses provided on a BNC connector. The internal rechargeable batteries provide 40 hours of operation between charges. For continuous operation, the SPSR can be powered by 115/230Vac. 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.
For convenience the SPSR 115/230 includes our most popular sensor, the ROS-P. The SPSR-IM is the interface module only and can be paired with any of the following (4) sensors (ordered separately) to best suit your particular application:
