Probes of 1000 mm (40”) normally have sufficient length for any 

installation.  Customers requiring probes longer than 1500 mm (59”) are 
supplied with a flow guide tube that uses the flue velocity to pull flue 
gas through a filter at the sensing tip and exhaust it near the flue wall. 

The probe can be configured in a variety of ways to suit the 

analytical environment. Figure 2-1 shows the most common 
configurable items of the probe. Not indicated is the actual 
thermocouple sensing element, however, see Table 2-1. You can choose: 

1.  Probe insertion length (from process end of mounting thread to 

probe sensing tip).  See Figure 2-2. 

2.   Mounting thread (process connection), BST or NPT (for size of 

thread refer to specifications).  

3.   Lagging extension length, if required. 

Table 2-1 indicates typical probe options.
