SF Series Dew Point Transmitter |
|
|
With a Measurement range (dew
point) of -40 to +60°C, dew point temperature the SF Series of Dew Point
Transmitters from Michell Instruments can provide 4-20mA or voltage signal for
either dew point or absolute humidity with excellent accuracy and linearity.
The robust housing, together with an operating pressure of up to 20 barg, makes
the SF Series ideal for many dew point and moisture measurement applications.
Product Features
- Dew point or absolute humidity outputs
- Current or voltage output signals
- Excellent linearity and temperature compensation
- Small size
- Digital recalibration
- Flush fitting filter disc for minimal flow disturbance
