Panel mount tachometer

Types of Panel Mount Tachometer

A panel mount tachometer is a device used to measure the speed of rotation of an axis or shaft. It is an instrument used in various fields ranging from automotive to industrial equipment. The panel mount tachometer is designed to be mounted on a panel or dashboard, allowing for easy visibility and access to the operator. There are different types of panel mount tachometers, including:

• Analog Tachometers

  These are the traditional tachometers that use a needle and a dial to display rotational speed. They are straightforward and reliable and don't need an external power supply.

• Digital Tachometers

  These display the speed of rotation in numerical form on a digital screen. They are more precise than analog tachometers and can often display additional information, such as average speed or max speed.

• Universal Tachometers

  These are designed to be used with various types of engines, including petrol and diesel. They are handy when working with unfamiliar engines or when multiple types of engines are used.

• Electrical Tachometers

  These use electrical signals to measure rotational speed. They are very accurate and can be used to monitor speed in real-time. Electrical panel mount tachometers are often used in industrial applications where speed control is critical.

• Contact Tachometers

  These panel mount tachometers must be in contact with the rotating shaft to measure speed. They are very accurate but can be tedious and unsafe when measuring speed on high-speed shafts.

• Laser Tachometers

  These are non-contact tachometers that use lasers to measure rotational speed. They are handy for measuring speed on small or delicate components where contact would cause damage.

• Wireless Tachometers

  These transmit the measured speed wirelessly to a display unit. They are useful for measuring speed in inaccessible locations or where multiple points need to be monitored simultaneously.

Specifications and Maintenance of Panel Mount Tachometer

Panel tachometers are devices used to measure the speed of rotating objects. They are typically used in vehicles to monitor engine speed, but they can also be found in industrial settings to track the speed of motors and other rotating equipment. The specifications of a panel tachometer can vary depending on the application, but here are some general specifications that buyers should be aware of:

• Measurement Range

  The measurement range refers to the minimum and maximum speeds that the tachometer can accurately measure. For example, a panel mount digital tachometer with a measurement range of 0-1000 RPM can measure speeds as low as 0 RPM and up to 1000 RPM.

• Accuracy

  Accuracy is the degree to which the tachometer can measure the actual speed of the rotating object. It is usually expressed as a percentage of the full-scale reading. For example, if a panel tachometer has an accuracy of ±2% FS, it can measure speeds within 2% of the actual value, regardless of the speed being measured.

• Resolution

  Resolution refers to the smallest change in speed that the tachometer can detect. It is usually expressed in the same units as the measurement range. For example, if a panel tachometer has a resolution of 1 RPM, it can detect changes in speed as small as 1 RPM.

• Display

  Panel tachometers may have analog or digital displays. Analog displays use a needle and dial to show the measured speed, while digital displays use numbers to show the speed. Some panel tachometers also have backlit displays for easy reading in low-light conditions.

• Power Supply

  Panel tachometers require an external power supply to operate. The power supply voltage and current requirements may vary depending on the tachometer model. They also come with different power supply options, including 12V, 24V, and 110V AC.

• Mounting

  Panel tachometers are mounted on control panels or dashboards using screws or brackets. The mounting method and dimensions may vary depending on the specific tachometer model. Some tachometers also come with removable bezels for easy mounting.

• Communication Interface

  Some panel tachometers may have communication interfaces, such as RS-232 or Ethernet, for data transfer and integration with other systems. This allows for real-time monitoring and data logging of speed measurements.

It is important to maintain panel mount tachometers to ensure accurate and reliable speed measurements. Here are some general maintenance requirements:

• Regular Cleaning

  Panel tachometers should be cleaned regularly to prevent dust, dirt, and debris buildup on the surface and the display. A soft cloth or brush and mild cleaning solution should be used. Harsh chemicals or abrasive materials should be avoided as they can damage the tachometer.

• Calibration

  Panel tachometers should be calibrated periodically to maintain accuracy. Calibration should be done using a reference tachometer or a calibration service. The calibration procedure and interval should be followed according to the manufacturer's instructions.

• Inspect for Damage

  The panel tachometer should be inspected regularly for any signs of damage, such as cracks, dents, or water intrusion. If damage is detected, the necessary repairs or replacements should be made to maintain the tachometer's performance.

• Replace Batteries

  Some panel tachometers may require batteries for backup power or memory retention. The batteries should be checked regularly and replaced when necessary or when they are low.

• Electrical Connections

  The electrical connections of the panel tachometer should be inspected regularly to ensure they are secure and free of corrosion. Loose or corroded connections can affect the tachometer's performance and accuracy. If necessary, the connections should be tightened, and corrosion should be cleaned using appropriate methods.

How to Choose Panel Mount Tachometer

Before buying a tachometer, it is important to understand the features and functions. Here is a guide on how to choose the right tachometer for different needs.

• Determine whether one needs an analog or digital tachometer: Digital tachometers display readings on LCD screens and are easier to read. They also provide extra information, such as average RPM and peak warning. On the other hand, analog panel mount tachometers have traditional dial displays that some people prefer.
• Consider the size: Panel mount tachometers come in different sizes. It is important to measure the mounting area in the dashboard or control panel and choose a size that fits properly and allows for secure installation.
• Consider the type of sensor: Different types of sensors are available to measure the RPM of the rotating object. Selecting a sensor compatible with the monitored system is important. Common sensors include inductive, optical, and contact sensors.
• Voltage and current requirements: Ensure the tachometer is compatible with the available electrical supply. Some models operate on 12V DC, while others require 24V DC or higher voltage.
• Environmental considerations: If the tachometer is to be used in harsh conditions, such as extreme temperatures, moisture, or exposure to dust or chemicals, selecting a model designed to withstand those environments is important.
• Additional features: Panel mount tachometers may include additional features that can be useful depending on specific needs. These features include data logging, alarm thresholds, peak hold, average RPM calculation, and backlighting for low-light conditions.

How to DIY and Replace Panel Mount Tachometer

It is very easy to replace a tachometer in a car. All that is needed is to follow the steps below

• Step 1

  Switch off the power supply of the vehicle or the power supply of the panel mount tachometer by removing the fuse.
