4.4 Piping for the Detector with Pressure
Compensation
The ZR22G----P Detector with Pressure Compensation may be used in System 2 and
System 3. However, it cannot use piping for high temperature probe adapter or blow back piping.
Use this detector whenever the furnace pressure exceeds 5 kPa (see Note). Even if the furnace
pressure is high, the detector can measure by adjusting pressure of the detector to the furnace
pressure using instrument air. The inside pressure of the probe will be kept the same as the
furnace pressure by feeding instrument air at higher pressure than that in the furnace.
NOTE
Sample gas pressure should not vary rapidly and widely.

Valve operation
1. For safety, stop the furnace that the detector is to be installed in. If furnace internal pressure
is high, this is especially dangerous.
2. Before starting instrument air ow, completely shut the stop valve in front of the reference
gas outlet.
3. Check that the reference gas outlet is not blocked by a ange gasket or the like.
4. Set the instrument air pressure higher than furnace internal pressure.
5. Completely open the stop valve in front of the reference gas outlet and, after turning on
instrument air ow, start furnace operation. As furnace internal pressure rises, conrm
that instrument air continues to ow and adjust the valve or increase supply pressure if
necessary.
6. After furnace internal pressure stabilizes, adjust ow.
7. If furnace operation is stopped, stop instrument air ow and completely shut the stop valve
in front of the reference gas outlet. You may leave reference gas owing if you wish.
