Air pressure sensor principle and precautions
The air pressure sensor is a control sensor that can be operated according to the barometric pressure end sensing. Inside the air pressure sensor, an air intake tube is provided that can promise air ingress, and once the power is applied, air can be transferred to the inside of the sensor, and when air enters, squeeze sensing occurs ...

Load cells with low power consumption and low cost – we are all in good hands
Types of load cells:
Electrical strain gauge load cells:
One widely used principle is the color of a resistive strain gauge (resistance strain gauge), where the resistance is changed to an electrical output, which is then passed through an instrument to measure the mass.
Capacitive load cells: low power consumption and low cost. The principle of ...

The wiring method of the photoelectric switch
P+F photoelectric proximity switch is called a photoelectric switch made of the photoelectric effect. The light-emitting device and the photoelectric device are installed in the same detection head in a certain direction. When a reflective surface (the object to be detected) is close to each other, the photoelectric device receives the reflected light and outputs it in the signal, so that it can be "...

Introduction of differential pressure sensors
A differential pressure sensor is a sensor used to measure the difference between two pressures, and is generally used to measure the pressure difference between the front and back ends of a certain equipment or component.
It is mainly used to measure the exhaust pressure difference between the front and rear channels of the exhaust particle trap (DPF) of the car engine.
In order to achieve a platoon ...

Factors influencing the measurement accuracy of ultrasonic sensors
Measurement accuracy generally refers to the affirmative accuracy of the measurement value of the analog output. Depending on the echo transmission moment, the measurement accuracy of the ultrasonic sensor relies on several physical parameters. These parameters are generally related to air and internal errors.
Environment...

Precautions for pressure sensors – a blessing
1. Avoid scum deposited in the catheter and contact the transmitter with corrosive or overheated media.
2. When measuring the gas pressure, the pressure port should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process.

The key factor influencing sensor performance – the company
Because the metal material is used as the elastomer of the load cell load cell, when the fine particles between the external force and the micro-strain disappear, the micro-strain disappears, but whether it can be fully recovered to the original non-stress state will be changed according to the metal data of the elastomer.

Photoelectric sensor sensing mode – Doublebless
The pass-through beam device consists of an acceptor located within the line of sight of the transmitter. In this mode, an object is detected when the beam is blocked from the transmitter to the receiver.
The retroreflective device places the transmitter and receiver in the same direction, and uses the reflector to ...

Sensor installation points – a blessing
Device points (device bolts)
The sensor of the device is fastened with high-strength bolts of the specified grade. (8.8, 10.9, etc.).
For sensors that require a gasket for the device, a washer must be placed on the bolt before it can be installed.

Illustrate the dynamic characteristics and linearity of our sensors
The dynamic characteristics of a sensor refer to the characteristics of the output of the sensor when the input changes. In practice, the dynamic characteristics of the sensor are often indicated by its echo to some normative input signals, because the echo of the sensor to the normative input signal is easy to obtain by experimental methods, ...

The new WIS2 wireless sensing system is available
The use of robots that can exchange things requires high-speed movement and fast rotation. Conventional solutions for energy chains or slip rings lack the necessary flexibility with regard to this automation technology. Our wireless sensing system (WIS) enables non-contact in places where a fixed connection is not possible.

The role and classification of safety barriers
In electrical intrinsic safety explosion-proof, we generally divide the workplace into explosion-proof areas and non-explosion-proof areas. There is the transmission of electrical energy between the explosion-proof area and the non-explosion-proof area, for example, the switches, buttons, sensors, etc. in the explosion-proof area are connected to the PLC placed in the electrical cabinet in the non-explosion-proof area through wires.

Features of the isolated safety barrier
The isolated barrier can be adapted for PCL applications. If the working environment of the field equipment is relatively bad, resulting in the signal sensing line of the PLC breaking the skin and connecting with other lines of different voltages or shorting to the equipment at the same time, there will be strong electricity into the pIc input port, which will cause the whole module to be burned, resulting in ...

How to distinguish between good and bad angle sensors
The use of angle sensors in practical manipulation is relatively common, and may be useful for the needs of different occupations and different fields. No matter how good the instrument is, there is a quality of the instrument itself, and in order to reduce the presentation of errors in the measurement process, users need to choose a good quality ...
