Gems Sensors & Controls has a strong reputation for collaborating with in-house engineering teams, bringing a detailed understanding of the design and operational factors involved with each application.
Often, the choice of sensor is dictated by the media to be measured, such as its specific gravity, viscosity or corrosiveness. Sometimes, design constraints relate to the best way to integrate the sensor, including its position, mounting and size within a restricted space.
