What should I Pay Attention to when Installing the Sensor?

Mar 10, 2020

With the development of the times, sensors are basically applied in various industries, and different types of sensors have different effects in different industries. So what should be paid attention to when installing sensors? Let Latch Type Hall Sensor Factory find it out.

First, the size of the mounting hole

If the size of the mounting hole is not appropriate, the threaded part of the high-temperature melt pressure sensor is easily worn during the installation process. This will not only affect the sealing performance of the device, but also make the sensor unable to fully function, and may even cause potential safety hazards. Only suitable mounting holes can avoid thread wear. Usually, the mounting holes are used to test the mounting holes for proper adjustment.

Second, keep the mounting holes clean

It is important to keep the mounting holes clean and prevent the molten material from clogging to ensure the normal operation of the equipment. "Before cleaning the extruder, all high temperature melt pressure sensors should be removed from the cylinder to avoid damage. When the sensor is removed, molten material may flow into the mounting holes and harden. If the residual melt is not removed In addition, the top of the high temperature melt pressure sensor may be damaged when the high temperature melt pressure sensor is installed again.

How to distinguish the authenticity of the sensor output signal?

China Hall Sensor has been applied to almost every industry in the contemporary era. These industries can record according to the signals sent by the sensors. So how do they distinguish the authenticity of the sensor output signals? Let's find out

1. Judging from the gap voltage

The output voltage signal of the vibration sensor includes direct current and alternating current. Direct current corresponds to the average distance between the sensor and the probe, also known as the gap voltage. Alternating current corresponds to a vibration signal. If the gap voltage is normal, then AC is usually normal.

2.Changes in Momentum and Gap Voltage

If the relationship between the vibration value and the gap voltage is consistent with the probe characteristics (7.87V / mm), that is, greater than ± 0.5V, then the vibration measuring instrument is likely to malfunction.

3. Judging from the change trend of axial vibration and tile vibration

Although the ratio of axial vibration and tile vibration is large and small, under normal circumstances, the axial vibration and tile vibration should change synchronously.

4. Judging by the output waveform of axial vibration

If electromagnetic interference, the output waveform has a large glitch, in addition to the power frequency component, there are a large number of 2x, 4x, 6x, 8x multipliers. Our company also has Hall Effect Sensor on sale, welcome to consult.
