TempVue 20 Pt100 Digital Air Temperature Sensor Meets World Meteorological Organization Recommendations Digital ambient air-temperature sensor Overview The TempVue™20 provides even greater flexibility to customers wanting the next generation of air-temperature measurements. This sensor meets all relevant World Meteorological Organization (WMO) temperature recommendations, but with a digital output that ensures maximum flexibility to meet all application needs. Designed with the customer in mind, the TempVue 20 easily interfaces with Campbell Scientific or third-party data loggers and fits a wide range of aspirated and passive temperature shields. The sensor comes with a short cable attached and terminates into an M12 connector, providing exceptional convenience, environmental protection, and data integrity for use in a variety of applications. Benefits and Features Status information, measurement averaging options, and calibration information onboard Incredibly easy to install or remove for calibration checks Durable and protected for even the harshest environmental conditions Meets all relevant temperature WMO recommendations High measurement stability over both time and temperature Calibration certificate included Technical Description The TempVue 20 consists of a wire-wrapped, four-wire Pt100 Resistance Temperature Detector (RTD) element encapsulated in an epoxy-filled, stainless-steel housing. The thin yet robust housing, combined with the Pt100 sensing element, provide a truly WMO-compliant sensor to meet the 20-second step response time with an ambient wind speed of only 1 m/s (3.3 ft/s). The digital TempVue 20 also gives users much more measurement confidence than an analog sensor is able to provide, such as status information and the removal of any hassles regarding calibration inputs. The TempVue 20 has a maximum measurement uncertainty of only 0.3 Kelvin over the entire measurement range of -60° to +60°C, with only 0.1 Kelvin over the most common temperature range of -40° to +40°C.
