Introduction
Accurate pressure signals are essential for monitoring fluid systems, supporting process control and identifying abnormal operating conditions.
The Meiyo Electric SMP-MB Pressure Transmitter converts pressure variations into a standardized 4–20 mA DC electrical signal for integration with control panels, monitoring systems and industrial instrumentation.
Compact Wall-Mounted Pressure Measurement
The SMP-MB uses a stainless-steel diaphragm with a thin-film strain gauge. This construction supports a compact transmitter design while converting mechanical pressure changes into a proportional electrical output.
Its wall-mounted enclosure facilitates installation, inspection and maintenance in industrial environments. An intrinsically safe version is also available for applications requiring installation in hazardous locations, subject to confirmation of the exact model and certification.

The pressure range, process connection and electrical configuration must be confirmed from the complete model code. The appearance of the enclosure alone is insufficient for identifying a technically compatible replacement.
Industrial Applications: Meiyo Electric SMP-MB Pressure Transmitter
The SMP-MB pressure transmitter may be evaluated for pressure monitoring in:
Marine machinery and auxiliary systems
Power-generation equipment
Oil and gas installations
Petrochemical and process plants
Pumps and fluid-handling systems
Industrial automation and control systems
Hydraulic and lubrication equipment
Suitability depends on the process fluid, pressure range, temperature, vibration, installation environment and required electrical or hazardous-area classification.
Information Required for Technical Selection
A defined SMP-MB requirement should include:
Complete existing model code
Required pressure-measuring range
Normal and maximum process pressure
Process fluid
Operating temperature
Process connection and thread specification
Electrical supply and 4–20 mA input requirements
Required measurement performance
Installation and mounting arrangement
Hazardous-area requirements, when applicable
Existing nameplate, drawing or equipment photographs
Required quantity
For replacement applications, the original model code and nameplate information should be verified before requesting an equivalent unit.
