Meiyo Electric R-96 Low-Temperature Platinum Resistance Bulb
Updated: 5 days ago
Nichiboku's industrial Insights
Introduction
Temperature measurement in marine machinery requires the sensor configuration to match the monitored medium, operating range, installation arrangement and connected instrumentation.
The Meiyo Electric R-96 is a terminal-box-type Pt100 platinum resistance bulb for measuring and monitoring temperatures in ship-engine systems. Confirmed applications include cooling water, lubricating oil, fuel oil, seawater and bearing systems. The manufacturer also identifies outside-air temperature measurement in its product description.

Response Performance for Marine Temperature Measurement
Meiyo Electric identifies response speed as an important performance requirement for low-temperature measurement.
The manufacturer states that the R-96 incorporates a resistance element with low thermal capacity and a construction designed to improve heat conduction. It also indicates that double-protection-tube construction can maintain characteristics comparable to single-protection-tube types.
This response behavior is relevant when monitoring temperature changes in lubricating oil, cooling water, bearings and other machinery conditions.

Specification Boundary and Replacement Selection
The temperature ranges, lengths and tube diameters shown above are published options. The manufacturer’s online information does not confirm that every possible combination is available or appropriate for every installation.
The standard specification identifies a single protection tube, while the product description also discusses the performance of double-protection-tube construction. The exact construction must therefore be confirmed from the applicable drawing or manufacturer quotation.
The following details are not established by the general online specification:
Exact process connection or mounting arrangement
Available combinations of temperature range, length and diameter
Required insertion depth
Complete installation dimensions
Terminal-box cable entry
Permissible process pressure
Installation-specific environmental requirements
Another sensor should not be treated as interchangeable only because it uses a Pt100 element, Class B accuracy or three-terminal wiring. The complete construction, dimensions, electrical characteristics and operating conditions require verification.
The accompanying product images are illustrative external views. They are not manufacturer drawings and must not be used to determine dimensions, materials, connections or installation compatibility.

Service Life and Condition Assessment
The official R-96 product information does not state a fixed service-life value.
Continued suitability should be evaluated from calibration results, resistance stability, thermal cycling, vibration exposure, protection-tube condition, terminal integrity, wiring condition and maintenance history. Installation age alone does not establish remaining service life.
International Sourcing from Japan
Nichiboku supports marine operators, industrial end users, maintenance departments, EPC contractors and procurement teams requiring identified Meiyo Electric temperature sensors from Japan.
