Temperature and Humidity / Atmospheric Pressure Transmitter / ENVIROsense
ETS60 (HVAC applications) / ETS68 (clean room applications) / ETS80 (outdoor weather/renewable energy applications)
Small high-precision temperature/relative humidity/atmospheric pressure (optional) transmitter
The ENVIROsense series is an environmental measurement transmitter that outputs temperature, relative humidity, and atmospheric pressure (optional) via RS485 Modbus-RTU. It is possible to additionally equip it with two analog outputs for temperature and relative humidity or dew point temperature as an option. There are three models available to suit different applications. ETS60: A cost-effective model for indoor HVAC applications (accuracy ±1.8%RH) ETS68: A high-precision model for clean room applications (accuracy ±1.2%RH) ETS80: A meteorological measurement model with a coating resistant to condensation, contaminants, and salt on the sensor (accuracy ±1.5%RH) With the installation of the protection hood HD9007A-1/2, it can also be used outdoors. All models can obtain the following humidity-related calculated physical quantities: Dew point temperature Water vapor partial pressure Wet bulb temperature Specific humidity Absolute humidity Frost point temperature Mixing ratio Saturation vapor pressure relative to water surface Specific enthalpy Saturation vapor pressure relative to ice surface
