Reuter-Stokes measurement equipment selection

Configure Reuter-Stokes sensing assemblies for turbines, downhole tools and radiation monitoring around your specification, interfaces and project scope.

Flame Tracker RS-FS-9001/9004/9006

UV flame detectors for gas turbines use a SiC photodiode. Define the installed detector code, cable arrangement and cooling configuration when specifying a replacement or project assembly.

RS-FS-9001, RS-FS-9004, RS-FS-9006
4–20 mA output signal
Check connector and mechanical interface
Cooling arrangement follows the selected version

Flame Tracker Dry 325

Remote electronics remove the need for water cooling. The hot and cool ends have different temperature limits, so define both components and their connecting arrangement in the project specification.

RS-FS-9009-03 and RS-FS-9010-03
Hot end up to +325°C
Cool end up to +140°C
Electronics separated from the hot location

Helium-3, Boron-10 and B10Plus+

Detector families support neutron and radiation measurement projects. The programme includes Helium-3 proportional counters, Boron-10 designs and hybrid B10Plus+ detectors.

Select the family for the measurement task
B10Plus+ combines ³He and ¹⁰B
Specify dimensions and electrical terminations

LPRM, TIP and nuclear instrumentation

BWR, PWR and SMR instrumentation covers flux detectors, probes, cables and mechanical equipment. Define the required channel and project specification before selecting the assembly.

BWR products include LPRM, TIP, SRM, IRM and WRNM
Drive mechanisms, gear boxes and motors
Detector housings and cable assemblies
Match the measurement channel specification

MWD, LWD and wireline detectors

Downhole gamma and neutron detectors integrate into drilling measurement and logging tools. State the tool platform, assembly boundaries, envelope dimensions and electrical interface.

Gamma sensors use NaI scintillators
Helium-3 based neutron detector designs
MWD, LWD and wireline applications
Agree the assembly scope against drawings

Orientation modules and fluxgates

Digital and analogue orientation modules form part of the downhole programme. Identify the module code, interface version and its position in the tool assembly when defining the scope.

Reuter-Stokes scope and current ownership

Reuter-Stokes makes sensing products for flame detection, radiation measurement, nuclear instrumentation and downhole tools. The brand became part of Crane when the acquisition from Baker Hughes closed on 1 January 2026.

Older installed equipment and archived documents may carry an earlier corporate name. Preserve the actual product identity when preparing a specification.

Separate the industrial plant, measuring instrument and replaceable assembly in your enquiry. The turbine or downhole tool name gives the application context; the Reuter-Stokes detector marking identifies the item to be configured.

In a mixed manufacturer bill of materials, highlight the relevant lines and retain their drawing references. This gives the project team a consistent basis for reviewing the equipment scope.

Prepare identification and installation references

Send the complete code, including hyphens, suffixes and revision information. Two photographs are useful: an overview of the installed assembly and a readable close-up of its marking.

Add both cable ends for a cable assembly, and show the connector and mechanical interface for an individual detector. Identify whether a packaging label belongs to that same item.

When a label is partly damaged, transcribe the legible characters and mark the gaps. Attach the relevant equipment list or drawing page with its position reference. List quantities, cables and mounting accessories as separate lines.

Keeping each code intact makes it easier to compare a proposed assembly with the installed configuration and with the project bill of materials.

Define the flame sensing assembly

Start with the installed detector model and the equipment that contains it. State whether the enquiry covers the detector alone or an assembly with cable and accessories. Preserve the distinction between Flame Tracker and Dry 325, because their physical arrangement and cooling approach differ.

For a configuration change, include the project connection diagram and required component list.

Describe the hot end, cool end and connecting route separately for Dry 325. Photographs of the mount and existing cable marking are useful for replacement enquiries. Provide the interface and installation requirements from your specification.

The proposed equipment scope can then be compared line by line, while the equipment owner retains responsibility for evaluating any change to the approved installation design.

Specify the measurement channel and its components

For radiation or nuclear instrumentation, identify the system, measurement channel and required assembly. Separate the detector, cable, housing and mechanical drive when they occupy different bill of materials lines. Include the existing assembly code and drawing position.

A new project should provide its agreed connection requirements and equipment boundaries.

Select Helium-3, Boron-10 or B10Plus+ around the measurement task and project data. A similar enclosure alone does not define the electrical configuration. A previous specification, current marking and accessory list are useful for a repeat order.

Keep LPRM, TIP and related nuclear instrumentation enquiries tied to the plant documentation so the proposed scope remains traceable through procurement and technical review.

Set the downhole assembly boundaries

For MWD, LWD or wireline projects, identify the tool manufacturer, platform and sensor position, followed by the complete existing component code. State whether you require a sensing element, an electronic module or a finished housed assembly.

Attach drawing dimensions and the electrical interface description used by your tool platform.

Keep gamma and neutron channels on separate lines. An orientation module should also have its own identification and scope. For a new configuration, include the interfacing component list and requested acceptance documentation. For a repeat order, state whether the tool design remains the same.

This lets the engineering and purchasing teams compare the proposed package with the actual integration work required.

From enquiry to equipment scope

SpareX reviews a single assembly or a project equipment list. First we match codes, quantities and package boundaries against the supplied references, then clarify open technical questions. You can send the available photographs and documents while marking the priority items.

The quotation preparation schedule is agreed after reviewing that information.

Retain your specification line numbers when listing detectors, cables and mounting accessories. State the receiving destination, packing requirements and the responsibilities expected for the export shipment.

Separate equipment selection from installation or commissioning services when these are different project packages. Check quantities and units for every line, particularly where individual sensors and complete assemblies appear in the same enquiry.

Receiving checks and configuration records

Agree which component codes and accessories belong in the final equipment list. Keep one approved specification with quantities and assembly boundaries. At receipt, compare the product and packaging markings, check package contents and record visible condition.

Photograph a discrepancy before the item is passed to the installation team.

For a cable assembly, compare both ends and the specified length marking with the agreed line. A package with multiple modules should be checked item by item.

Receiving checks form part of your procurement record; the equipment owner still applies its own technical acceptance and installation procedures. Retain the documents against the component identification so a future enquiry can refer to a traceable configuration.

Attach a useful enquiry package

A useful starting package contains the complete identification, quantity, marking photographs and equipment name. For an assembly, add a drawing with position references or an equipment list page. Show a removed component in full and include separate views of its connection points.

Describe the purpose: a repeat order, a damaged component replacement, a maintenance package or a new equipment project.

Keep your line order and identify components that must be considered together. The form can carry the code and task, with detailed references attached as files. Check that small label characters remain readable.

Include a response contact so the project team can clarify the technical information that determines the proposed equipment scope.
