Then, variopol (VP8) cable connection option, for quick cable-to-sensor release, eliminates cable twisting.

Ordering Information
Rosemount 398R/398RVP sensors offered in 21 inch and 36 inch titanium tube sensor lengths. Then sensors can use with a ball valve (sold separately) for hot tap applications. However, Rosemount 398 sensors come standard with 15 ft. of integral or 9.5 in. cable for use with a sensor head junction box (sold separately). Therefore, Rosemount 398RVP sensors are SMART preamplifier optional and are used with quick disconnect VP8 interconnecting cables (sold separately).

Features and Applications
Rosemount 396R and 396RVP Sensors are specifically designed for improved life in harsh, dirty applications where a separate sample stream is difficultto provide and greaterinsertion depths are required. These sensors are designed for use with a 1-1/4 in. or 1-1/2 in. ball valve for hot tap installation.

Wiring for Rosemount 396R
Make electrical connections as shown on Figures 3-1 through 3-15 using the following guidelines.
For wiring Rosemount 396RVP, see Section 4.
1. Pay particular attention to the analyzer or transmitter model number when following details on the wiring diagrams to ensure.
2. Use Rosemount custom cable Part Number 9200273 for interconnect.
3. The maximum distance from the sensor to the transmitter is 15 ft without an integral preamplifier.
4. Signal cable should run in a dedicated conduit and should keep away from AC power lines.

Recommended pH Sensor Standardization
For maximum accuracy,the sensor can standard on-line or with a process grab sample after a buffer calibration has perform.

Standardization accounts for the sensor junction potential and other interferences.
Standardization will not change the sensor’s slope but will simply adjust the transmitters reading to match that of the known process pH.
1. While obtaining a process solution sample (the sample is closing to the sensor), record the pH value is showing on the transmitter display.
2. Measure and record the pH of the process solution sample with a another temperature compensated, calibrated pH instrument. For best results, standardization should be performed at the process temperature.
3. Adjust the transmitter value to the standardized value.

It’s RUGGED THREADED POLYPROPYLENE BODY for maximum
chemical resistance and completely sealed to eliminate process intrusion. EPDM to eliminate process intrusion.

The 396P and 396PVP sensor is housed in a molded polypropylene body with EPDM seals, making it virtually indestructible and chemically resistant. Complete encapsulation eliminates leakage or high humidity problems traditionally found in other pH/ORP designs.

Firstly, this trending data allows technicians to predict frequency of maintenance. Additional SMART features include factory calibration, resetting SMART sensor calibration data with user menus.

Then, the TUpHTM large area reference junction for minimum maintenance requirements: The reference junction provides an electrical connection between the reference electrode and the sample. And helps maintain a stable reference potential, regardless of the change in sample pH.

What’s more, the TUpH reference electrode junction, and the entire plastic tip surrounding the glass pH electrode. Because it resists plugging (a common cause of pH signal drift).

The Model 396P and 396PVP sensors are available in two configurations.

First, the standard shrouded tip, in which the pH glass completely recess within the reference junction for abrasive or rough applications.

Second, the optional slott tip with a partially exposed pH glass for viscous or low flow applications.

Importantly, the Model 396P and 396PVP sensors feature a titanium solution ground, constructe in an annular design around the pH/ORP electrode. However, the solution ground provides advanced sensor diagnostics for preventative maintenance.
