5.9.2 Piston/Spring exit
Pack the exit orifice of the furnace wall with high-temperature ceramic fiber (e.g. Kaowool™)
insulation to keep outside connections cool. Install plate and spring, tighten collar at desired
location. Install split washers and pipe cap.
WARNING!
Excessive temperature at the transition
Exceeding 175 °C [350 °F] at the transition could damage the sensor
▶
Ensure transition does not exceed 175 °C [350 °F] and is a minimum
150 mm [6 in] from the furnace entry connection.
5.10 Cable connections
The cable gland must be sealed to ensure that the required protection class is reached.
Requirements for meeting ingress protection
■
Only use cable glands within their indicated clamping range (cable diameter suitable for
the cable gland).
■
Ensure proper clamping range is met when using very soft cables.
■
Only use circular cross-section cables (if necessary, slightly oval in cross-section).
■
Do not twist the cable.
■
Repeated opening/closing is possible; however only if necessary, as it might have a
detrimental effect on the protection class.
■
For cables with a pronounced cold-flow behaviour the screw connection must be fully
tightened.
