Contact Campbell Scientific for details. The CS115 was a barometric pressure transducer with a measurement range of 600 to 1100 mb (below sea level—as in a mine—to approximately 12,000 feet); the overpressure limit was 1375 mb. The CS115 was manufactured by Druck, Inc. as their model RPT410F.
The CR500, CR510, CR10, CR10X, CR23X use the Period Average Instruction (P27) to measure the CS115. The CR7 and 21X use the Pulse Count Instruction (P3). The CR1000, CR3000, and CR5000 uses the PeriodAvg Instruction; the CR9000(X) uses the PulseCount Instruction.
