Models of square proximity switches

There are several reasons for the formation of zero drift of high-frequency pressure sensors: 1. There are bubbles or impurities in the adhesive layer of the strain gauge 2. The function of the strain gauge itself is unstable 3. There are virtual solder joints in the circuit 4. The stress release of elastomers is incomplete; In addition to the magnetic field, ...

1. Self-conditioning. At the beginning of use, please check whether the switch itself is defective and whether the appearance is defective. 2. When using the EL130 photoelectric switch to avoid obstructions, some goods such as colored goods. Less reflective goods. Goods with large gaps between small pieces ...

Torque sensor is a sensor widely used in the mechanical category, which can measure the torque of rotating objects, and torque sensors have a wide range of application scenarios, and several typical application scenarios will be introduced below. First of all, the short-term sensor is widely used in the automotive industry to measure the engine and transmission.

1. Test for NPN output sensor The NPN sensor output, also known as OC gate output, is based on the principle of open collector output of a transistor. The principle of NPN type OC gate output is whether the output of the NPN transistor and GND are short-circuited. When the control is active, the transistor is turned on, the output and the GND ...

1. It is necessary for the sensor to be properly installed Damage to high-temperature pressure sensors is usually caused by their installation in improperly machined holes. When a sensor is loaded into a hole that is too small or has a migraine, it may damage the sensor diaphragm and cause the instrument to not function properly. Can...

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 ...

There are two common types of sensor switches: NPN type and PNP type, so what are the differences and differences between them? For example, there is a switch VT in the NPN open collector output circuit, and the output OUT is through the switch ...

A device that converts the value of a force transducer into an associated electrical signal. Force is the direct cause of changes in the motion of materials. Force sensors can detect tension, tension, pressure, components, torque, internal stresses, and strains. The specific equipment is metal strain gauges, pressure sensors, etc., which have become electric ...

The displacement sensor has no sliding contacts, is not affected by non-metallic elements such as dust during operation, has low power consumption, and has a long service life, so it can be used in various bad conditions. Displacement sensors are mainly used to intelligently control the analog quantity of automation equipment production lines. The displacement sensor selects laser three...

The principle of NPN type OC gate output is whether the output of the NPN transistor and GND are short-circuited. When the transistor is turned on, the output and GND ( ...

1. Shielding skills Containers are made from metal materials. Wrapping circuits that require maintenance between them can effectively prevent the disturbance of electric or magnetic fields, which is called shielding. Shielding can be divided into electrostatic shielding, electromagnetic shielding and low-frequency magnetic shielding. 2. Electrostatic shielding ...

An encoder is a device that compiles or converts signals or data into signals that can be communicated, transmitted and stored – encoders can be divided into two categories: incremental and absolute. Incremental encoders are the most important way to convert bits ...

In the process of modernization, the SLP series of safety barriers is gradually forming a modular safety system, constantly innovating, and on the basis of innovation, more stringent requirements for quality. VISOLUX offers a wide range of beams ...

An important function of the photoelectric switch is to be able to handle changes in the intensity of light: the light beam is changed by using optical components in the transmission medium; Use a beam of light to reflect objects; Instantaneously returns the light emitted by the beam over a long distance. 　　The photoelectric switch (photoelectric sensor) is a photoelectric proximity on...

Auxiliary mechanical devices: commonly used are rack and pinion, chain belt, friction runner, rope reeling machinery, etc. Low-speed end device: installed behind the reduction gear, such as the shaft end of the winch wire rope drum or the shaft end of the next reduction gear ...

1. Conceptual sensor: It can sense the specified signal under test and correlate the signal into an electrical signal. Transmitter: Comply with the necessary algorithm rules to convert the measured electrical signal into a standardized industrial control signal. (1) Sensitive element refers to the sensor that can directly (or as a response) ...

Optical fiber sensor and photoelectric sensor are two typical sensors, which are widely used in production and measurement, so what is the difference between the two? Fiber optic sensor skills are developed on the basis of fiber optics, optical communications, and optoelectronic skills, and electromagnetic...

(1) Conductive plastic displacement sensor Conductive plastic displacement sensor uses a special process to coat the DAP (didipropylphthalate) resistance paste on the insulating body, heat and polymerize to form a resistive film, or press the DAP resistive powder thermoplastic into the groove of the insulating matrix to form a solid body as a resistor.

WirelessHART uses the 2.4 GHz band (which is no-nonsense and globally) as a transmission medium for a variety of radio skills, including WLAN, Bluetooth, and ZigBee. However, WirelessHART is more than just a variant of WLAN. ...
