An introduction to the work of ifm controllers

1. It is necessary to insist on parallel between the front end surface of the photoelectric sensor and the surface of the workpiece or object to be detected, so that the conversion efficiency of the photoelectric sensor is high. 2. When installing and welding, the root of the pin of the photoelectric sensor and the pad ...

The mass flow manipulator is a new type of flow measurement and monitoring instrument, as well as an instrument that can conveniently monitor the flow of different gases in pipelines without temperature and pressure compensation. Its operating principle is to send the flow signal measured by the heating bridge of the sensor to the amplifier for amplification.

First, the application environment of the weighing system Sensors operating in high-temperature environments should use high-temperature resistant sensors, and especially harsh occasions must also be equipped with heat-insulation, water-cooled or air-cooled devices. For use in alpine areas, load cells with heating devices should be considered. ...

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.

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. ...

Because the load cell has the advantages of high measurement accuracy, good temperature characteristics, and stable operation, it is widely used in the dynamic and static measurement of various structures and the primary appearance of various electronic scales. The load cell can be selected with two different input and output wiring methods: one is ...

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 ...

Whether it is a linear displacement sensor or a rope displacement sensor, it often encounters a variety of problems when it is used, including quality problems, application problems, environmental problems, etc., but the use of problems is common, and improper use simply makes the sensor damaged. So what we're using ...

IFM sensor is a sensor with optoelectronic devices as the conversion element, which can be used to detect non-electric amounts that directly cause changes in light quantity, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc.; It can also be used to detect other non-electric charges that can be converted into changes in the amount of light, such as part diameter, surface ...

1. Proximity switch selection Different types of proximity switches should be selected for different raw material detectors and different detection intervals to have a high-performance price ratio in the system, for which the following principles should be followed in the selection: 1. When the detector body is metal material, the high-frequency oscillation type should be selected.

1. The exhaust temperature of the refrigeration unit is high, the coolant level of the refrigeration unit is too low, the oil cooler is dirty, the oil filter core is blocked, the temperature control valve is faulty, the oil-off solenoid valve is not energized or the coil is damaged, the oil-cut solenoid valve diaphragm is broken or aging, the fan motor is faulty, the cooling fan is damaged, and the exhaust pipe is not ...

1. If the electronic ruler has been used for a long time, and the seal is now aging, it is mixed with a lot of impurities, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers constantly beat. At this time it can be said that the electronics of the linear displacement sensor ...

Zero drift is an important indicator that affects the function of the pressure sensor, so when the problem occurs, we should pay attention to it, so what is zero drift? Zero drift refers to when the input signal of the expansion circuit is zero, due to the influence of temperature changes, power supply voltage instability and other factors, so that ...

1. Start with the bus east and west As a first step, the engineer should take the approach of first interfacing the sensor, which is through a bus stuff to constrain the ignorance. A bus thing connects to a personal computer (PC) and then to the sensor for I2C, SPI or other ...

Thanks to a uniquely adjustable sensor, it can be flexibly adapted even in wet environments ●After touching the sensor, the ergonomic plan is selected for work ● Open delay can prevent unintentional opening ...

Diagnose sensor faults based on mathematical models? When there is a problem, the first time is to diagnose it, see where the problem is, so that it is easy to deal with, from different angles, we use more than one method when diagnosing the problem, if this is classified, it can be divided into two ...

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 ...

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.

Decentralized processing of signals, good readability of different process parameters and freely selectable scale factors Clear, easy-to-read display It can be equipped in different formats via IO-Link or the setting menu Beyond or without reaching ...

1. The appearance is installed outdoors, and it is recommended to install a sunshade to prolong the service life of the appearance. 2. Wire and cable protection pipes should be sealed to avoid water accumulation. 3. Although the appearance itself is equipped with lightning protection equipment, when the appearance is used in the multi-lightning area, it is advocated to distinguish the inlet and outlet lines on the surface.
