Flange
Mount Transformer Coupled
Torque Sensor Model T250 Series
Mechanical
Interface
The Model T250 Series Rotary Transformer Torque Sensor,
utilizes flange-to-flange mounting configuration, which
further compliments the already unique miniature size, and
will reduce installation expense and complexity. The T250
Series is designed for use with a wide variety of
mechanical couplings, however special care must be taken
in proper coupling selection. Each application must be
evaluated on the basis of torque levels to be transmitted,
misalignment to be compensated for, torsional vibration
present, critical speed factors, and system dynamics. The
factory will be pleased to assist you with a list of
coupling manufacturers upon request.

Dimensions
and Specifications are subject to change without notice.
Please request certified drawings prior to the
design of mounting fixtures.
