More Information

Overview Manuals ORP Circuit Reference Stability Installation Choices Product Applications

Features:

  • True ORP configuration: code 12 selects a platinum measuring electrode
  • Extended integral lead: code 02 supplies 15 ft (4.57 m) of coaxial cable without a preamplifier
  • High-solids reference design: the TUpH junction and helical pathway resist coating and poisoning
396P-02-12-55 measures ORP from -1500 to +1500 mV using the platinum option in the rugged Rosemount 396P body.

Its longer 15 ft lead supports remote instrument placement while retaining the direct, non-preamplified sensor signal.

The same front and rear process threads let designers choose insertion, immersion, or flow-through mounting for the intended vessel or line.

Apter Power can review 396P-02-12-55 electrode identity, cable length, analyzer input, installation method, and documentation before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Platinum electrode: code 12 establishes the oxidation-reduction potential measurement.
  • Measurement span: the official ORP range is -1500 to +1500 mV.
  • Direct signal: code 02 contains no integral preamplifier.
  • Long lead: the sensor leaves the body on a 15 ft (4.57 m) coaxial cable.
  • Large-area junction: the TUpH interface limits the effect of surface coating.
  • Helical pathway: the extended reference path slows contaminant migration.
  • Polypropylene structure: the reinforced body supports chemically demanding aqueous processes.
  • Analyzer group: code 55 identifies the five listed Rosemount instrument families.
  • Dual process threads: 1 in. MNPT connections are provided at both ends.
  • Insertion duty: the front process connection supports line or vessel entry.
  • Submersion duty: the rear thread accepts the documented immersion assembly.
  • Flow-through duty: a compatible cell or tee can place the electrode in a controlled sample stream.
  • Dirty-process ORP measurement: the TUpH reference design addresses coating exposure.
  • High-solids vessels: the rugged body supports immersed oxidation-reduction monitoring.
  • Abrasive aqueous streams: the long reference path helps protect signal stability.
  • Flow-through analysis: the threaded sensor body can be installed in the documented cell or tee arrangement.
Description
396P-02-12-55 configures the Rosemount 396P platform for oxidation-reduction potential rather than pH. A platinum measuring electrode works with the TUpH reference system inside the reinforced polypropylene sensor body for demanding aqueous process service.

The electrical identity of 396P-02-12-55 comes from its code-02 lead: a 15 ft integral coaxial cable with no internal preamplifier. Code 55 associates the sensor with Rosemount 56, 1056, 1057, 1066, and 5081 instruments that support the corresponding ORP input.

Mechanical versatility remains a practical strength of 396P-02-12-55. Matching 1 in. MNPT threads on the front and rear support insertion, submersion, or flow-through layouts, while the large-area junction and long reference path address coating and high-solids exposure.

Technical notes
396P-02-12-55 is the platinum ORP configuration, not the GPLR pH version. Its code-02 cable is 15 ft long and contains no integral preamplifier; connect it only to the documented code-55 Rosemount instrument group with the channel configured for ORP, then establish the site reference and diagnostic baseline.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is 396P-02-12-55 intended for pH or ORP measurement?
It is the ORP configuration. Code 12 selects a platinum electrode, so the connected analyzer channel must be configured for oxidation-reduction potential rather than pH.
What does the code-02 cable mean for 396P-02-12-55?
It provides a 15 ft integral coaxial lead without a preamplifier. Protect the cable from moisture, sharp bends, and noisy power conductors, and follow the selected analyzer terminal diagram.
Which instruments can receive 396P-02-12-55?
Code 55 lists Rosemount 56, 1056, 1057, 1066, and 5081. The individual instrument must still provide the required ORP input and matching termination.
How should 396P-02-12-55 be placed in an open tank?
Use the rear 1 in. MNPT connection with the documented submersion hardware, keep the cable entry protected, and position the platinum surface where it remains wetted by representative process liquid.
What can cause an unstable reading from 396P-02-12-55?
Inspect coating on the platinum surface, reference-junction condition, cable moisture or damage, grounding, analyzer input selection, process mixing, and whether the electrode remains fully wetted.
What commissioning record is useful for 396P-02-12-55?
Store the complete order code, analyzer model and channel, installation point, cable route, process temperature, stabilized millivolt value, verification solution result, and the initial alarm limits.
