Industrial sensors and measuring instrumentation

Specialists in industrial measurement, control and monitoring

GUEMISA is a company specializing in industrial sensors and instrumentation for the measurement, control, and monitoring of processes, machinery, test benches, and industrial facilities. We supply solutions for measuring pressure, temperature, level, position, displacement, inclination, speed, force, weight, torque, humidity, water quality, and other physical quantities.

Our catalog includes sensors, transmitters, encoders, inclinometers, load cells, torque sensors, data acquisition equipment, indicators, converters, and signal conditioners. We work with specialized manufacturers and select each piece of equipment based on measurement range, accuracy, output signal, mounting, and actual operating conditions.

In addition to supply, we offer technical consulting, equivalent product searches, equipment configuration, custom solutions, and calibration management. We serve machinery manufacturers, engineering firms, integrators, laboratories, and industrial companies in Spain and Portugal.
