High temperature survival
Submersible
Stainless steel
Infinite resolution
The PY non-contact displacement transducer measures the distance between its front face and a target made
from a ferritic material. A ferritic material is one which is attracted by a magnet.
This sensor is appropriate for high temperature, high pressure and high nuclear radiation position
measurement applications. Many applications in turbines, in nuclear power stations and in research labs are
appropriate for this sensor.
There are two types of PY transducer, a single coil version (which must be used in pairs) and a double coil
version which can be used alone.
As the output of the PY is not linear, linearisation may be necessary depending on the application. Our 615
amplifier is designed for this.
The single coil displacement transducer
version must be used in pairs for example
one on each side of a rotation shaft.
