Metravi NCTM-1000 Non-contact Type Tachometer

A. Product Overview

The Metravi NCTM-1000 Non-contact Type Tachometer is a digital RPM measuring instrument used to measure the rotational speed of machines and rotating components without touching the object. It combines photoelectrical technique, microcomputer technology and laser measurement in one compact handheld instrument.

It supports two test modes: RPM mode for rotational speed measurement and count mode for revolution counting. The instrument has a 5 digit LCD display with backlight, built-in memory, Max, Min and last value recall, and a wide RPM test range of 2 RPM to 99,999 RPM. It also offers a count range of 1 to 99,999 counts and a detecting distance of 50 mm to 500 mm.

B. Working Principle

The Metravi NCTM-1000 works on a non-contact photoelectric and laser sensing principle. A reflective mark or reflective tape is placed on the rotating object. When the tachometer is aimed at the rotating surface, the laser detects each reflection from the mark.

The instrument counts these reflected pulses and converts them into RPM or revolution count. Since the measurement is done without direct contact, there is no mechanical loading on the rotating part and the measurement remains safer for high-speed or moving machinery.

C. Why It Is Used

The Metravi NCTM-1000 is used when the speed of a rotating object needs to be measured quickly, safely and accurately. It is especially useful where direct contact with the shaft, wheel, fan or motor is difficult, unsafe or impractical.

It is commonly used for checking motor RPM, fan speed, pulley speed, conveyor roller speed, pump rotation, machine spindle speed and general industrial maintenance. The non-contact design helps technicians take readings from a safe distance while the machine is running.

FAQ

1. What is the Metravi NCTM-1000 used for?
The Metravi NCTM-1000 is used to measure RPM and revolution count of rotating objects such as motors, fans, pulleys, shafts, rollers, pumps and industrial machines.

2. Is the Metravi NCTM-1000 a contact or non-contact tachometer?
It is a non-contact tachometer. It measures RPM using laser and photoelectric sensing without physically touching the rotating object.

3. What is the RPM range of the Metravi NCTM-1000?
The RPM test range is 2 RPM to 99,999 RPM, making it suitable for low-speed and high-speed rotating equipment.

4. What is the detecting distance of this tachometer?
The detecting distance is 50 mm to 500 mm, allowing the user to take readings from a safe working distance.

5. Does the Metravi NCTM-1000 have a digital display?
Yes, it has a 5 digit LCD display with backlight, which helps users read measurements clearly in different working conditions.

6. Can it measure both RPM and count?
Yes, the instrument has two modes: RPM mode for rotational speed and count mode for total revolution counting.

7. Is it suitable for motor RPM measurement?
Yes, it is suitable for motor RPM measurement, fan speed checking, pulley speed measurement and other rotating machine applications.

8. Does it store readings?
Yes, it has built-in memory recall for Max, Min and last value, which helps users review important readings during testing.

9. What type of users need this tachometer?
It is useful for maintenance engineers, technicians, motor repair shops, manufacturing plants, HVAC service teams, machine builders and industrial testing professionals.

10. Why choose a non-contact tachometer instead of a contact tachometer?
A non-contact tachometer is safer and easier to use on moving or high-speed parts because it does not need physical contact with the rotating object.
