GUEMISA: specialists in sensors and industrial instrumentation
We select and supply sensors, measuring equipment and industrial instrumentation for engineering firms, machinery manufacturers, laboratories, maintenance companies, and industrial plants.
In addition to offering standard equipment, we provide technical advice to determine the measurement range, accuracy, output signal, mounting type and the most suitable working conditions for each application.
More than 40 years providing measurement solutions
GUEMISA's journey began in 1985, when two electronics specialists founded the company with the aim of supplying components and technical solutions to the Spanish market.
In its early years, the company focused on membrane keyboards, transformers, relays, and other electronic components. Over time, the company expanded its specialization to include... sensors, signal converters and measurement systems.
Currently, GUEMISA is a second-generation company that continues to combine experience, technical knowledge, and direct collaboration with specialized manufacturers.
Sensors and instrumentation for industrial applications
We work with equipment designed to measure and control numerous physical quantities and process variables:
- Pressure, temperature and level.
- Position, displacement and inclination.
- Force, weight, torque, and vibration.
- Humidity, water quality and meteorological variables.
- Speed, frequency, and other electrical or mechanical signals.
We also supply conditioners, isolators, converters, indicators, recorders, data acquisition equipment and industrial communication solutions.
This variety allows us to address applications in machinery manufacturing, automation, civil engineering, energy, automotive, environment, water, laboratories, industrial maintenance and other technical sectors.
Technical advice for selecting the right equipment
Each measurement application has different requirements. Therefore, before proposing equipment, we analyze aspects such as:
- The magnitude and range that needs to be measured.
- The required precision and resolution.
- The output signal and the available control system.
- Mechanical assembly and electrical connection.
- The materials in contact with the process.
- Temperature, humidity, vibrations, and other environmental conditions.
- Communication and integration requirements.
The goal is not to offer any sensor that approximately meets the requirements, but to find a technically suitable, reliable, and proportionate solution for each project.
Standard equipment and customized solutions
We represent manufacturers specializing in different measurement technologies and select their products based on the needs of each application.
When a standard device doesn't fully meet the project's needs, we explore potential modifications, special configurations, or custom developments. This may include changes to the device's range, output signal, wiring, encapsulation, mechanical connection, or communication capabilities.
A long-term technical collaboration
We understand our relationship with our clients as a technical collaboration. We provide support during product selection, quotation preparation, installation, and resolving any questions after delivery.
We work with companies throughout Spain and Portugal, catering to both one-off needs and recurring projects, serial manufacturing and special applications.
