Step 2 -Install The Remote Sensor - Bacharach Neutronics 5100E Operation Manual

2.1.2 Step 2 –Install the Remote Sensor
The Model 5100E is supplied with a Model ZR-500E oxygen sensor, and sensor flow-through head for
connection to a sampled process gas stream, and a sensor interface cable. The Model 5100E can also be
supplied with a Neutronics Inc. process Sampling system, built-to-application. NOTE: For instructions on
the installation of a Neutronics Inc. Process Sampling System, please refer to the sampling system
equipment manual.
2.1.2.1 Flow-through Head
Surface-mount the flow through head horizontally (as shown in figure 9) or vertically on a stationary panel.
The sensor flow-through head is 1.25" diameter stainless steel, and is machined to accommodate two # 6-
32 machine-type mounting screws (1-inch on center). Be careful not to over tighten the mounting screws.
Allow sufficient space to screw the Model ZR-500E oxygen sensor into the top threaded port of the flow
through head, and for the sample lines and sample inlet and exhaust fittings.

2.1.2.2 Sample Inlet Port
Pneumatic connection to the measured process for sample extraction is made at either of the two
interchangeable 1/8" FNPT fitting around the side of the flow-through head. For connecting the flow-
through head to the measured process, use 1/8" or 1/4" rigid tubing, and 1/8" MNPT fittings of a material
compatible with process gas composition. Ensure that no grease, particulate, or solvent is present in the
tubing during installation. Use thread-tape to seal connections, and prevent gauling. Fix all sample tubing
and connectors.
A fixed calibration port may be implemented in the process sampling line by installing a 1/8" or 1/4" 3-way
manual ball valve into the sampling line as in figure-9. Use 1/8" or 1/4" rigid tubing and 1/8" MNPT fittings
of a material compatible with process gas composition. Ensure that no grease, particulate, or solvent is
present in the tubing during installation. Use thread-tape only to seal connections, and prevent galling. Fix
all sample tubing and connectors.
