Absolute Humidity/Temperature Transmitter / HD3817T Series
Senseka (formerly Delta Ohm)
● The HD3817T is an absolute humidity and temperature transmitter with a 4-20mA output, while the HD38V17T has a DC0-10V output. ● Absolute humidity is the ratio of the amount of water vapor to the volume of air, expressed in units of g/m³. ● The maximum operating temperature of the sensor is up to 200℃. This feature makes it suitable for harsh industrial applications where conventional capacitive sensors cannot be used. ● Fast response time and quick recovery time from saturation are also characteristics of this sensor. ● The maximum measurement range is absolute humidity from 0 to 130g/m³ and temperature from 0 to 200℃. ▲ Maximum operating temperature of the sensor is 200℃, allowing for high-temperature measurements. ▲ Fast response time and recovery time from saturation. ▲ 4-20mA output or 0-10V output. ▲ Probe stem lengths of 127mm/227mm and cable lengths of 2m/5m.
