DataCheck™ Wireless Sensor Power & Control Doc #600200 Transmitter Specifications Spread Spectrum scheme: frequency hopping Operating Frequency Range: Multiple channels within the 902- 928 MHz ISM band Operating temperature: -40 ° F to 150° F Enclosure rating: IP- 67 Maximum Sensor Power: 6 VDC @ 13 mA Sensor Telemetry Duty Cycle: programmable 10 seconds to daily or event-driven using the master discrete input Battery type: 2 proprietary Lithium Thionyl Chloride D Cells (16.5 Ah, 10 year shelf-life) Agency Approvals: CSA approved (US/C) Class I Div. 1 Groups C&D, Exia Overlapping Systems: Each DataCheck™ system is assigned a unique ID code so that multiple systems can coexist within a small area. Battery powered for up to 5 years Intrinsically Safe (Exia) Innovative Sensor Solutions, Ltd. ' s DataCheck™ is a wireless telemetry system used to power and control a variety of low-voltage intrinsically-safe (IS) sensors and transmit their data from hazardous areas. DataCheck™ employs state-of-theart super high energy density lithium ion batteries and a patented sensor powering and control interface to provide long-term intermittent power and telemetry for a variety of low-power sensors. DataCheck™ systems consist of IS, battery operated sensors, transmitters, repeaters (if needed), and receivers. The proprietary 900 MHz frequency-hopping Spread Spectrum technology provides numerous advantages, including: Reliability: DataCheck™ transmitters are " fully supervised" to ensure that they are actually communicating with their assigned receivers. The battery condition of each transmitter is monitored, and " Low Battery" alarms are issued about 1 month before batteries must be replaced. Data is transmitted very redundantly over multiple channels to ensure ultrareliable communication even in the presence of noise and RF interference. Licensing: DataCheck™ products are FCC approved for unlicensed operation in the 900 MHz ISM band. Superior Range: Multiple Repeaters may be employed to extend range around obstructions or over much greater distances.
