The laminar flow status is monitored with the help of one of the measurands and an associated value range. On delivery, the EE680 monitors the standardized air velocity using the factory preset values according to Tab. 4. Via the EE-PCS, the standardized air velocity vn or the temperature can be selected for monitoring together with the according range upper and lower limit (refer to Fig. - Page 15 The vn measurement response time t can be changed in the range between 1.5 and 40 s. The factory setting is 1.5 s. User Manual EE680 Air Velocity and Temperature Sensor for Laminar Flow...
