DELTA OHM (Italy) have recently launched a new series of temperature and humidity transmitters that are specifically designed for heavy industrial applications where chemical contaminants are present in the atmosphere and high ambient temperatures are encountered such as the chemical and paper industries and wood drying kilns.
The HD3817 absolute humidity transmitter series, available from W & B Instruments , measure absolute humidity over the range 0 to 130g/m3 and temperature over the range 0 to 200°C.
The Absolute Humidity sensor allows direct control of moisture levels. With a fast response time and a quick recovery time from saturation, the Absolute Humidity sensor is immune to most chemical contaminants unlike the capacitive film type sensor used in humidity control systems.
Other features of the HD3817 absolute humidity transmitter include:
- Voltage and current output models
- Stainless steel probe
- IP66 protection for the electronics housing
Probe and cable lengths are available in a number of standard lengths. Alternatively, units can also be ordered in no standard ranges and varying probe and cable lengths.
