2 Description of the BROSA force measuring pin
2.1 Structure and functionality
Type 0201 and 0203 BROSA force measuring pins are used to measure the force in double
shear connections in or on machines and devices of all kinds.
Fig. 1: Force measuring pin
The force measuring pin consists of a cylindrical measuring body (1), that absorbs the load to
be measured and exhibits the properties for torsional and axial securing (1a) as well as a
connection support (2) firmly connected to the measuring body in some cases, on which - if
not placed directly on the measuring body - the necessary elements for the electrical
connection (plug or cable, 3) are attached and which - if not placed in the measuring body -
contains the measurement electronics. The recess (1b) in the measuring body for technical
measurement reasons can be provided with a filling depending on the application or
optionally on request. Optionally, the measuring body can contain elements to lubricate the
bearing (1c). The Ex d Type 0203 force measuring pin is always equipped with a threaded
pin (4) for electrical potential equalisation (optional in the other types). The measuring body
and connection support, if applicable, are made of stainless steel.
The MOP force measuring pin contains integrated mechanical overload protection.
