Page 27: Removing The Immersion Tube
Immersion Tube SensoGate WA 133 Removing the Immersion Tube Conditions: First, separate the immersion tube from the process adaptation (see “Removing the Drive Unit” chapter). 1. Move the drive unit to PROCESS position until the two screws (Z) become visible. Loosen the two screws (Z) using a screwdriver (TX 25) until they contact the stop at the immersion tube (see illustration). -
Page 28: Installing The Immersion Tube
Immersion Tube SensoGate WA 133 Installing the Immersion Tube Conditions: The retractable fitting must be in PROCESS position (see “PROCESS Position” chapter). 1. Push the O-ring (D) (sensor gasket) onto the sensor (A) as shown. 2. Note: Make sure that there is no further O-ring in the immersion tube (T) (installed by mistake). -
