Installation | 3-7
Follow the steps below to install the probe heater:
1. Remove and discard the plug from the probe heater port as shown in
Figure 3-3. This port is plugged during shipment and should remain
plugged if no probe heater is installed.
2. Screw the probe heater into the 3/8” NPT probe heater port.
3. Route the wires from the probe heater to the sensor board.
4. Remove the sensor terminal box cover and connect the wires from the
probe heater to Terminals “M” and “N” on the sensor board - polarity
is not required.
Exhaust tube Installation
If installing an exhaust tube, you must connect it to the sensor before
mounting the sensor to the process.
Enclosed in the envelope with the probe heater is a stainless steel exhaust
tube that allows you to extend the aspirator exhaust. The exhaust tube can
be identified by having a thread on only one end of it.
To install the exhaust tube, thread the exhaust tube into the exhaust port
on the rear of the sensor as shown in Figure 3-3.
sensor Mounting
•
The sensor ambient temperature range is -20 °C to 70 °C.
•
When installing a probe heater or exhaust tube along with the sensor,
attach it to the back of the sensor before mounting the sensor to the
process.
•
If your sensor has a lift-off lid, allow at least 10” (25.4 cm) above the
sensor so you can remove the lid and access sensor components.
Do not open a Z-purge, hinged-sensor enclosure door until you first
verify that the area has been classified as nonhazardous.
