Displacement measurement in severe environments.
Reliable displacement measurements in severe environments?
RDP has the answers.
Transducer specialist RDP Electronics offers a comprehensive
range of displacement sensors specifically designed to operate
in harsh environments.
The PY and LIN series are used in applications involving high and
low temperatures, excessive pressures and even nuclear radiation.
The LIN range of contacting displacement sensors uses a linear
differential inductance principle (LVDT) for measurement ranges
from 10mm up to 50mm. The range includes options for maximum
operating temperatures of either 220°C or 600°C. The design of
the LIN transducer has also proved successful at pressures of
3000psi, minimum temperatures down to ­220°C and in nuclear
radiation doses up to 100,000 MegaRads.
The compact PY range has been designed for non-contact
proximity measurements in similarly harsh conditions.
PY sensors use a variable reluctance principle to measure
the distance of a metallic target from the sensor over ranges
of 1.5mm to 6mm.
