How Does A Treadmill Speed Sensor Work

The most common exercise equipment are jogging treadmills and stationary bikes. Knowing the best time to buy a treadmill is really beneficial. Moreover, the functionality of a treadmill, speed and  how accurate are treadmills really matter. How does a treadmill speed sensor work? The front roller’s revolutions per minute are recorded by the treadmill’s speed sensor, and the computer converts this reading to miles per hour. 

The speed sensor is connected to a circuit board that communicates with the treadmill control panel on the majority of models. The display screen may display an error code when issues with the sensor arise. This most frequently implies a bad or loose sensor. 

A voltage metre can be used to test the internal circuits for continuity to find issues with the speed sensor. The speed sensor can then be fixed from there.

Symptom Of Faulty Optical Speed Sensor:

  • Motor makes strange noises.
  • Running belt fluctuates in speed and has problems maintaining it (irrespective of whether there is a person on the machine).
  • After a while, the motor fails.
  • Motor briefly runs before cutting out nearly immediately.

System Performance:

The system uses a magnetic speed sensor to track the running belt speed and enables precise recalibration of the console display (kph/mph) between various models. This reduces expenses by allowing the same electronics to be used by several treadmills.

However, because the magnetic sensor responds slowly, speed variations may result (a perceptible lag while the system makes automatic adjustments to maintain a set speed). This is also the reason why it can take up to 10 seconds for an E1 speed sensor malfunction to manifest.

The optical sensor operates significantly more quickly. It enables the system to offer a very consistent belt speed by allowing it to react to speed variations very fast. Additionally, it enables the system to shut down quickly in the event of a problem because it allows the system to notice a problem far earlier than the magnetic sensor.

As a result, the producer may exchange electronics between several models and provide a very responsive control system by using the two speed sensors.

Treadmill Speed

Fixing the Treadmill Speed Sensor:

Step 1

Remove the treadmill’s power plug. The bolts holding the motor cover to the front of the treadmill can be removed using an Allen wrench. To access these bolts, it might be necessary to remove the hub covers on either side of the treadmill, depending on the type. The motor cover should be removed and stored.

Step 2

Follow the white and black wire leads down to the circuit board, starting at the motor. Remove the terminal posts on the circuit board’s black and white connectors. Find the bolts holding the mounting bracket for the treadmill motor in place. To loosen and remove the bolts, use an Allen wrench or socket and ratchet.

Step 3

To slack the drive belt, lift the motor end away from the front roller pulley. Extend the belt away from the motor pulley. To access the speed sensor on the motor’s underside, position the motor upright. 

Verify the sensor’s stability in the bracket that attaches it to the motor. Use a screwdriver to tighten the screws and secure the bracket if the sensor is not sturdy.

Step 4

Follow the sensor’s wire lead down to the circuit board. From the circuit board, remove the connector. Using a voltage metre, check the speed sensor wiring circuit for continuity. The speed sensor has to be changed if the metre indicates continuity.

Step 5

Attach the speed sensor to the bracket at the motor’s bottom by screwing it in place and tightening the screws. The circuit board must be connected to the wire lead. Reconnect the motor to the mounting bracket, install the drive belt on the motor pulley, and tighten the bolts holding it in place.

Step 6

The circuit board should be connected to the motor’s black and white leads. Attach the hub covers to the treadmill frame’s sides. Put the motor cover on. Connect the treadmill’s power line to a wall socket. To reset the treadmill, adhere to the directions in the owner’s manual.

What You Will Need:

  • Allen wrench
  • Socket and ratchet
  • Voltage meter
  • Screwdriver

Tips:

To ensure the speed sensor area’s appropriate and long-lasting operation, always take precautions to keep it clean and clear of dust and dirt particles.

Warnings:

To prevent electrocution, shock, or burn injuries, make sure there is no power flowing through the machine before attempting to repair any internal components.

Conclusion

What is a speed sensor? How does a treadmill speed sensor work? These worth knowing questions are explained in this article. The location of the speed sensor on an electronic treadmill is probably near the motor assembly at the front roller, where it counts each rotation to determine speed and distance. 

That sensor will provide erroneous information and result in inconsistent, variable speed if it starts to malfunction. The sensor either has to be replaced or it can be modified. 

Without a lot of additional equipment or specialised knowledge, a home treadmill can be repaired and diagnosed. All the steps of fixing the speed sensor are explained above. 

FAQ’S

What does a treadmill speed sensor do?

The front roller’s revolutions per minute are recorded by the treadmill’s speed sensor, and the computer converts this reading to miles per hour. The speed sensor is connected to a circuit board that communicates with the treadmill control panel on the majority of models.

Are all treadmills equipped with speed sensors?

magnetic speed sensor for a treadmill. suitable with all home fitness product brands. This sensor is a replacement for all 2-pin sensors, regardless of shape.

Why does my treadmill speed up all of a sudden?

Variable Speed. Spend some time watching the treadmill to check for belt hitching. This is frequently a clue that your belt needs replacing. If a machine shuts down, there can be an issue with the motor or a circuit might be broken.

How frequently should a treadmill be lubricated?

Three months in a row. If you use the gadget regularly, you should lubricate it every 130 miles, or every three months. Check your treadmill more frequently if you use it more frequently to see whether maintenance is required. Waiting until you hear squeaking or another sound that would suggest unwelcome friction is not a good idea.

Are the treadmill’s speeds reliable?

Overall precision. The computation procedure ensures that it is frequently extremely accurate. The reading is unaffected by the user’s weight, the intensity of the workout, or the treadmill’s incline. It’s crucial to remember, though, that treadmills might not always offer an accurate distance measurement.
