Glass Tubing for Sensors
Accurate sensors depend on glass tubing with high geometrical tolerances, as well as precise light transmittance, electrical insulation, and a matched CTE to metals and alloys for effective bonding.
UV light sensors
SCHOTT offers glass tubing with very high UV light transmittance, making them ideal for UV sensors. Each section of the electro-magnetic spectrum demands specialty glass tubing, with the ability to be sealed to tungsten and Kovar alloy a key requirement.
The highly sensitive detection of light performed by UV-transmitting photomultipliers depends on glasses with exceptionally high UV light transmission, such as SCHOTT 8337B. This unique glass offers further processing at low temperatures, as well as a stable glass-to-metal bond.
Electroanalytical sensors such as pH electrodes require protective glass tubing with high electrical resistance to offer a strong seal with the pH-sensitive membrane. Glass tubing also provides stable environmental protection for gas sensors.
Liquid level sensors
In tanks and boiler systems, the levels of the liquid inside are measured with sensors using glass with outstanding thermal resistance and mechanical strength. This provides highly accurate measurement of extremely high pressures.
The right glass tubing for the task
SCHOTT’s portfolio of glass tubing for sensors covers a vast range of applications and requirements, with our experts able to quickly assess your needs and recommend the ideal glass type, dimensions, tolerances, and processing options.
