DWYER RHP-W系列掛墻式溫濕度露點變送器的詳細描述：
產(chǎn)品名稱: RHP-W系列掛墻式溫濕度露點變送器
產(chǎn)品型號: RHP-W系列
產(chǎn)品介紹：
The Series RHP-W Wall Mount Humidity/Temperature/Dew PointTransmitter is the most versatile room transmitter on the market.The stylish housing is well vented to provide air flow across thesensor to improve measurement accuracy. An optional LCD display canbe integral to the transmitter or a remote display can be orderedfor building balancing or LEED? validation. The LCD displayindicates the ambient temperature along with the humidity or dewpoint. The transmitter has internal dipswitches to select thetemperature engineering units and whether the transmitter outputshumidity or dew point.
The humidity and temperature sensors are field replaceable toreduce service cost and inventory. The humidity and the dew pointare measured using a capacitive polymer sensor that compleyrecovers from 100% saturation. The humidity and dew point can haveeither a current or voltage output, while the optional temperatureoutput can be a current, voltage, RTD or thermistor. For modelswith current or voltage for the temperature output, the temperaturerange is field selectable.
