Dimensional Drawings - Mounting Details

Sensor inserts

DIN housing with G1/2A male nipple connection
and sensor insert

Note {8}
Housing shaft

DIN housing: 11.5 mm

ø80 housing: 6.5 mm

Calculation of insert length:
When ordering an insert the length must be calculated from the
formula:

Insert length = Sensor length + total body length + housing shaft
(Total body length can be calculated from the dimensional drawings on
pages 6 and 7)

Example.
Insert for a G1/2A male nipple sensor in a DIN housing, 100 mm
sensor tube, normal response sensor tip:

Housing shaft = 11.5 mm
Total body length = 27.5 + 12.5 = 40 mm (see page 6)
Sensor length = 100 mm

This insert must be ordered with a 151.5 mm sensor tube.
