are required which can withstand high pressure.
Sensors are available to a pressure level of up to 80 MPa (800 bar). Standard type
sensors are used for a range of approx. 500 kPa – 1 MPa (5 – 10 bar). 15.1.6 Inductive proximity sensors with large switching distance
The potential switching distance is determined primarily by the size of the resonant
circuit coil. Large switching distances therefore require larger coils.
Proximity sensors with large switching distances are for instance of advantage in
cases where alternating distances occur between the object to be detected and the
proximity sensor, e.g. as a result of position tolerances or different object sizes. Example Inductive proximity sensors in plastic housings of 80 mm, 90 mm or 100 mm dia.
with switching distances of 50 mm, 70 mm or 100 mm. Switching distances of
45 mm and 90 mm can be achieved with metal housings of 100 mm and 200 mm dia.
