ZR22R - Oxygen Probe Protectors and Support

Oxygen Probe Protectors and Supports Explained 

Probe Protector (ZR22R)

The probe protector (ZR22R) is a stainless-steel tube attached to a flange that provides full-length protection for the ZR22 oxygen probe. The probe protector should be used on the ZR22 oxygen probe when there is a high particulate load (coal-fired) and a flow rate of 10 m/sec (33 ft/sec) or greater.

• Material: 316/316L stainless steel, schedule 10 pipe
• Flange: 4” ANSI class, 150# FF flange
• Four holes are countersunk for installation to the process flange.
• Available Lengths: 0.4 meters to 3 meters

Probe Protector (ZR22R) Installation

The probe protector (ZR22R) flange has four recessed holes and four regular holes, which allow the probe protector to be integrally mounted to the flange process and the ZR22 oxygen probe flange without degrading structural integrity.

 

1. Install the probe protector (ZR22R) with the long end toward the process gas flow. Install the bolts into the recessed holes of the ZR22R flange. 

2. Insert the probe protector mounting bolts into the recessed holes of the probe protector flange and through the process flange. Torque as necessary to achieve a good seal.

3. Install the ZR22 oxygen probe into the probe protector and the process flange.

4. Insert the ZR22 mounting bolts into the ZR22 oxygen probe flange and torque as required to achieve a good seal between the probe flange and the probe protector flange.

Probe Support (ZR22V)

The probe support (ZR22V) provides additional structural support for probes over three meters in length. The probe support is suitable for applications without particulates, such as natural gas-fired units.

• Material: 316/316L stainless steel, schedule 10 pipe; 1.5 m insertion length
• Flange: 4” ANSI class, 150# FF fange
• Four holes are countersunk for installation to the process flange

Probe Support (ZR22V) Installation

1. Install the probe support (ZR22V) into the process flange opening.

2. Install the probe support mounting bolts into the recessed holes of the probe support and torque as necessary to achieve a good seal.

3. Install the ZR22 oxygen probe into the probe protector and the process flange.

4. Insert the ZR22 mounting bolts into the ZR22 oxygen probe flange and torque as required to achieve a good seal between the probe flange and the probe protector flange.
