The Shimpo DT-205LR-S12 portable contact/noncontact tachometer
has a 12-inch wheel, measures rotational speed, linear speed, and
total length, and has a laser beam for noncontact measurements.
This portable contact/noncontact tachometer has a 12-inch wheel
and is used for measuring the speed of motors, conveyor belts,
and other moving and rotational systems. It measures rotational
speed, linear speed, and total length for flexibility of use. Its
optical sensor is a laser beam that works at a distance from 1
inch to 20 feet for user safety. The five-digit LCD screen
presents test results and the unit of measurement. It stores up
to 13 readings, including the maximum, minimum, and last test
result values for ease of data recall. A die-cast aluminum body
provides durability in harsh environments, and the device can be
tripod-mounted and locked to take continuous measurements. The
tachometer conforms to NIST standards for compliance with
regulations, and the CE mark indicates compliance with applicable
EU directives. It comes with a 12-inch wheel, a contact adapter,
two cone adapters, a funnel adapter, a 3.5-inch extension shaft,
a carrying case, reflective tape, and an NIST certificate. This
tachometer is suitable for measuring rotational speed and other
measurements in mechanical or industrial engineering
environments. The laser in the DT-205LR is Class II and has less
than <1 mW of output.

is depth, the horizontal distance from front to back.
Tachometers measure the rate of rotation or surface speed of
motors, conveyor belts, and other moving systems. Contact
tachometers take measurements through direct contact with the
moving surface, and can measure both rpm and surface speed.
Typically, contact tachometers come with a range of attachments
that can be used to measure speed on different kinds of rotary
systems, which may include tips used for measuring shafts with a
central hole or flat end surfaces, and rotary wheels for
measuring conveyor belts. Noncontact tachometers take
measurements from a distance using a beam of infrared light, and
provide highly accurate measurements. Contact tachometers are an
excellent choice for dirty and dusty environments; noncontact
tachometers only calculate rpm but are considered safer because
they do not require the operator to be in close contact with the
moving surface. Contact/noncontact tachometers, also known as
dual, or combination tachometers, can be used to take contact and
noncontact measurements. Some tachometers can also take other
types of measurements, such as count or frequency, while others
can output data to a computer for analysis. Tachometers are used
in applications such as automobile maintenance, mechanical
engineering, and maintenance of industrial equipment.
Shimpo Instruments manufactures force, torque, and speed
evaluation instruments. The company, founded in 1974 and
headquartered in Itasca, IL, meets International Organization for
Standardization (ISO) standard 9001. The laser in the DT-205LR is
Class II and has less than <1 mW of output.
