Keller titanium pressure transmitters and pressure sensors

Keller offers titanium versions of its products for use in heavily corrosive media. The company has developed an implantable sensor made of titanium, offering a host of advantages for applications under special conditions.

If a sensor is made of steel, it can only be exposed to temperatures up to a maximum of 60°C. At higher temperatures, the heat-induced expansion of the oil causes so much deformation of the steel diaphragm that it no longer returns to its original position. By contrast, the titanium diaphragm shows no deformation up to 120°C, which also makes stability errors less likely than in products with steel diaphragms. This is because the modulus of elasticity is only half as high.

At Keller, titanium is used to manufacture high-quality transmitters that meet demanding stability requirements. Components made of titanium will not corrode even in salt water or chlorinated water, making it suitable for process measurement technology applications involving wastewater that may be contaminated with unknown corrosive substances. Titanium housing also makes it possible to carry out hydrostatic level measurements effectively in brackish water or even iron chloride.
