1. According to the measurement object and measurement environment In order to carry out a detailed measurement operation, it is necessary to consider the principle of the sensor first, which needs to analyze many factors before confirmation. Because, even if the same physical quantity is measured, there are sensors with multiple principles to choose from.

Temperature sensor 1. The sensor should be firmly grounded, and the wire side of the sensor should not be short-circuited. 2. The thermistor of the moving magnet water thermometer sensor will increase with the temperature and the resistance value will decrease. Fuel level sensor ...

First, press the [Acknowledge] button to enter the first-level menu, press the [Up] or [Down] button to find the menu you want to set, and press the [Acknowledge] button to enter the set value, which will be displayed at this moment. Long press the [Up] or [Down] button, when the value starts flashing, continue to press to adjust the ...

The first point is that photoelectric sensors and fiber optic sensors work differently First of all, from the principle of operation of the two, first of all, the photoelectric sensor is operated according to the principle of the photoelectric effect, that is to say, when the light hits the photoelectric sensor made of semiconductors, the light will be announced.

1. Inspection distance Detect the stop, start and orientation of elevators and lifting equipment; Detect the orientation of the vehicle to avoid collision between two objects; Detect the setting orientation of the operating machinery and the limit orientation of the moving machine or components; Detect the abort azimuth of the rotary body, the opening or closing of the valve; Detection of cylinders or hydraulic ...

1. Whether the temperature of the measured target needs to be recorded, alarmed and automatically controlled, and whether it needs to be measured and transmitted at a distance; 2. The size and accuracy requirements of the temperature measurement scale; 3. Whether the size of the temperature measuring element is appropriate; 4. In the measured ...

1. What are the basic requirements of ultrasonic level gauge? When transducers emit ultrasonic pulses, they all have a definite opening angle. From the lower edge of the transducer to the surface of the measured medium, there should be no obstructions in the area radiated by the emitted ultrasonic beam.

Proximity sensor is a general term for sensors that replace touch detection systems such as limit switches and aim at detecting objects without touching them. It converts the moving and possessive messages of the detected target into electrical signals. ...

1. Traditional communication protocol flooding. The message is sent to a nearby node in the form of a broadcast, and the node that receives the information continues to broadcast in the same way until the audio reaches its destination. Pros: Simple and easy to do, no maintenance required. Cons: A certain node may ...

The first step in selecting a pressure sensor is to determine the pressure to be measured. Exciter sensors are divided into mechanical pressure and pneumatic pressure (hydraulic). The mechanical pressure unit is generally N.KN.KGF, etc. The pneumatic and hydraulic units are generally KPA, MPa, PSI, etc. This article describes the selection of mechanical pressures. ...

Conceptual understanding of sensors The sensor is a kind of detection device, which can sense the measured audio, and can convert the perceived audio into an electrical signal or other required audio output according to the inevitable discipline, so as to satisfy the transmission, disposal, storage, display, recording and control of the audio.

1. After the wireless sensor device is installed, it appears to be beating or the number is inaccurate Reason: There is electromagnetic interference on the site, or the signal line and the power line go to the same trunking. Solution: The product function selected by the customer does not meet the on-site working conditions, and it needs to be installed or replaced.

(1) Fork photoelectric sensor Placing a light emitter and a sticker face to face on either side of a slot is a fork photonics. The luminaire can announce infrared or visible light, and the luminaire can receive light in an unobstructed environment. But when the object to be detected passes through the slot, the light is blocked ...

There are two types of accelerometers: one is the angular accelerometer, which is improved from the gyroscope. The other is a linear accelerometer. It can also be divided into single-axis, dual-axis and three-axis accelerometers according to the measurement axis. ...

Capacitive sensors can detect any object without touch. In contrast to inductive sensors, which can only detect metals, capacitive sensors are also capable of detecting non-metallic materials. principle 1. The first thing to be measured is ...

Vortex flowmeter series instrument because of the use of the environment is special or harsh in the field work sometimes present such and such problems, resulting in production will be affected, vortex flowmeter and orifice flowmeter and V-cone flowmeter are different, as far as the orifice flowmeter is concerned, it is the standard orifice plate and multi-parameter ...

Temperature sensor definition A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core part of the temperature measurement appearance, and there are many varieties. The temperature sensor is very accurate in measuring the ambient temperature, and is widely used in agriculture, industry, ...

(1) Large-scale In order to obtain accurate information, many sensor nodes are usually arranged in the monitoring area, perhaps in the tens of thousands, or even more. The large-scale nature of the sensor network contains two implications: on the one hand, the sensor nodes are distributed in a large geographic area, such as in the original ...

The pressure sensor usually refers to the component-level product of non-standard mV signal output, which is the core component of the pressure transmitter. Due to the weak signal, the demand increases at longer intervals.

Capacitive ifm sensors have many applications in everyday life. It is capable of inspecting non-metallic materials as well as non-touch methods to detect objects. The editor below explains how the sensor works. Capacitive ifm sensors ...

Easy-to-install sensor with long-service life electronic GMR unit – flush unit This sensor can be conveniently installed in a C-slot Fixed at the end of the housing for stable elastic stress relief Multiple articulations ...
