The AEMC CA1720 Series portable contact/noncontact tachometer measures rotational speed, linear speed, frequency, period, duty cycle, and count, has an infrared beam for noncontact measurements, and a digital display. This contact/noncontact portable tachometer is used for measuring the speed of motors, conveyor belts, and other moving and rotational systems. It can measure rotational speed, linear speed, frequency, period, duty cycle, and count for versatility. Its optical sensor is an infrared beam that works at a distance from 1 to 50cm for operator safety. It has a digital display to present test results and units of measurement, and the display incorporates an analog bar graph for readability. This tachometer can store up to 4,000 measurements and has functions and automatic routines for data acquisition and storage. It is rated to IP 51 level of protection against dust and dripping water, and it comes with an FRB F connector, a 9V battery, 15 reflective strips, a hard case, and instructions. The AEMC model CA1727 tachometer also comes with a USB cable and software for data analysis. This tachometer is suitable for measuring rotational speed and other measurements in mechanical or industrial engineering environments.

Specifications

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D 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.
