If there is a pressure difference between the location of installation and the process, the measurement can be several tens of degrees dew point off. The exact effects of changes in pressure on the dew point can be simulated using the E+E hu- midity calculator. Please find further details on our website www.epluse.com.

• an excessive process temperature • protecting the sensor against soiling • the need to remove the probe without interrupting the process. To obtain a representative sample of the process gas and to avoid measuring errors, please note Manual EE355 Dew point transmitter... -
Page 9: Basic Sampling Cell
The sampling cell is specially developed for use in compressed air lines and has a quick-connec- tor suitable for standard compressed air connections DN7.2. This allows the cell to be fitted and removed without interrupting the process. The flow of gas can be adjusted using a bleed screw. Pressure range: 0...10 bar (0...145 psi) Order code: HA050102 G 1/2“ ISO Bleed screw Quick connector DN7.2 Pic. 5 Sampling cell with quick connector Manual EE355 Dew point transmitter... -

Dew point adjustment by the user is possible only at low dew points. The adjustment can only be carried out if the difference from ambient temperature to the reference dew point temperature is <-60 °C. Example: Ambient temperature = 20 °C Reference dew point temperature must be lower then -40°C. Manual EE355 Dew point transmitter... -

1) The accuracy statement includes the uncertainty of the factory calibration with an enhancement factor k=2 (2-times standard deviation). The accuracy was calculated in accordance with EA-4/02 and with regard to GUM (Guide to the Expression of Uncertainty in Measurement). 2) Field-attachable mating connector is included in the scope of supply.
