TEMPERATURE/HUMIDITY TRANSDUCERS TEMPERATURE/HUMIDITY CONVERTERS R220 Series Temperature/Humidity Transducers R320 Series Temperature/Humidity Transducers HN-GR Series Temperature/Humidity Converters R220 SERIES TEMPERATURE/ HUMIDITY TRANSDUCERS These transducers are dry and wet bulbs type temperature/humidity sensors with ventilating function, which can measure temperature/humidity at calm condition. Resistance thermometer Measuring range Measuring condition : Wind speed less than 3m/sec. R320 SERIES TEMPERATURE/ HUMIDITY TRANSDUCERS These transducers are dry and wet bulbs type temperature/humidity sensors. Since the units are designed to measure temperature and humidity at places where the wind velocity exceeds 3m/sec. continuously, the ventilating Resistance thermometer Measuring range Measuring condition : Places where the wind velocity exceeds 3m/sec. HN-GR SERIES TEMPERATURE / HUMIDITY CONVERTERS These converters indicate simultaneously both temperature and humidity by combining with the temperature/humidity transducers, R220 series or R320 series, and output analog Input signal : Dry bulb temperature and wet bulb temperature Input range Output signal Conversion Accuracy

TEMPERATURE/HUMIDITY TRANSDUCERS & CONVERTERS HUMIDITY TRANSDUCERS MODELS R220 (Standard type) R221 (Automatic water-feeding type) These compact and lightweight transducers are dry and wet bulbs type temperature/humidity sensors with ventilating The units employ two platinum resistance thermometers as temperature detecting elements for dry and wet bulbs, and consist of a ventilating unit, detecting elements, and a water tank for wet bulb, and others. Since the water tank is detachable and a terminal board is exposed when tilting the units forward under the wallmount condition, the wiring, check...

HN-GR SERIES TEMPERATURE/ HUMIDITY CONVERTERS These converters indicate simultaneously both temperature and humidity by connecting with the temperature/humidity transducers, R220 series or R320 series, and output analog signals of 4 to 20mA. 6 kinds of humidity unit such as absolute humidity and relative humidity are selectable to display and output. The humidity and temperature outputs are isolated and arbitary scalble on both outputs. Also, communication interface is available as an potion. MODEL HN-GR3F1 Communication interface N : Not provided R : RS232C A : RS422A S : RS485
