This is a technical specifications document for pressure transducers required by the Natural Resources Conservation Service (NRCS) for use in the automated snowpack telemetry (SNOTEL) network operated by the Alaska Data Collection Office (AKDCO). The NRCS seeks GE TERPS digital pressure sensors (Part# DPS813F-TB-A1-CC-H0-PE) to provide data readings for precipitation and snow water equivalent (SWE) measurements within the SNOTEL system. The specified transducers must feature a 0-2 Bar range, 25mm stainless steel silicon exposed element, RS-485 digital output, polyurethane cable with water-tight connection (15 feet length), operating temperature range of -40 to +85°C with full thermal calibration, and a 1/4" NPT female pressure connection. These sensors require high accuracy and thermal stability to maintain standardized data quality across the SNOTEL network.
