Information

With the continuous increase of elevator ownership, elevator safety problems caused by elevator failures have attracted great attention of the society. G-TEK provides customized products and solutions according to elevator industry standards. Elevator light curtain is a kind of elevator door safety protection device based on photoelectric induction principle which is suitable for all elevators to protect passengers entering and leaving the elevator; Poximity sensor and level switch sensor participate in real-time monitoring of elevator operation in order to ensure the safety and reliability of the system.

What kind of sensor is the Hall sensor used in elevators?

Elevators generally use a large number of sensors for safety protection, movement limits, program start, and other functions. The application of the sensor is also different. One of the elevator leveling controls used in the Hall switch is what it is, today we will take you to understand the principle and classification of Hall sensors.

Elevator Leveling Control Sensor Solutions:

In the case of elevator failure, how the elevator stops moving is very important, if the elevator's sensing device is not sensitive enough, failing the sensing device makes the elevator not stop moving in time, which will cause danger to passengers. The leveling device mainly consists of the device that detects the position of the car. At present, Hall sensors and photoelectric switches are widely used in medium and high-speed elevators to realize the precise leveling of the elevator.

Do you know what U-type photoelectric sensors are used in elevators?

Elevator is one of the essential facilities in modern buildings, and its safety is directly related to the life and property safety of passengers and objects. In order to ensure the safety of the elevator, the elevator is equipped with various safety devices. U-type sensor belongs to one kind of photoelectric sensor, its transmitter and receiver are located at the left and right ends. A one-piece design makes installation more convenient. It is mainly used in the leveling control system of the elevator.

Proximity sensors principle of operation and product classification

Proximity sensors are also known as non-contact detection switches. Typically 2-8 sensors are installed in an elevator. This type of non-contact detection does not wear and tear and does not damage the object to be detected. Compact size, fast response speed, so popular in the market. Today we get to know the working principle and product classification of proximity sensors.

Elevator Door Anti-trap Sensor Solution：

In recent years, a number of incidents have occurred around the world in which passengers blocked elevator doors for a long period of time with thin objects such as wooden boards, iron plates, and tiles. The elevator started the forced closing function, resulting in serious damage to the floor door, and door machine system of the accident. Condemnation of such uncivilized use of elevator behavior at the same time, as elevator manufacturers and suppliers, must also be on the elevator door anti-clamping protection device and forced closing protection function re-improvement. So how should we pick the elevator door anti-pinch sensor?

How to choose the right proximity sensor?

Proximity sensors play an integral role in the automation of industrial production. Today we will discuss how to choose the right proximity sensor, what are the elements of picking a proximity sensor, and how to check and inspect proximity sensors.

_{Practical applications of elevator light curtains}

_{An elevator light curtain is a kind of light-type elevator door safety protection device, applicable to passenger elevators and freight elevators, to protect the safety of passengers. One side of the light curtain has several infrared transmitter tubes installed at equal intervals, and the other side correspondingly has the same number of infrared receiver tubes in the same arrangement, forming a dense infrared protection light curtain. When any of the lights are blocked, the control system immediately outputs a signal to open the door, to achieve the purpose of safety protection, and to avoid the occurrence of elevator clip accidents.}

Elevator Motor Speed Sensor Solutions:

The rotational speed is an important parameter reflecting the operating state of rotating machinery, which is the result of the joint action of rotating machinery power moment, inertia moment, and load moment. Through the measurement of the instantaneous value of the rotational speed, you can quantitatively understand the rotating machinery's internal power generating device's instantaneous working state, understand the load application process, to ensure the normal operation of the equipment, analyze the transient performance of the machinery, mechanical fault diagnosis to provide a basis. There are four main methods for measuring rotational speed, namely, mechanical, electromagnetic, photoelectric, and laser.

Troubleshooting solutions for elevator light curtains

An elevator light curtain is a kind of elevator door safety protection device made by using the principle of photoelectric induction, which is applicable to all elevators and protects the safety of passengers entering and leaving the elevator. So in the daily maintenance of the elevator, the elevator light curtain equipment repair and maintenance is very important. Is the elevator light curtain bad how to repair it? This article lists a few common elevator light curtain failure solutions for your reference.

Various safety sensors in elevators

The device that makes the elevator run in balance is the sensor. There are many kinds of sensors applied in elevators, and each elevator uses 2-8 sensors, such as displacement sensors, load cells, light curtain sensors, leveling sensors, speed encoders, and so on.

Elevator door switch in place sensor solution:

The elevator door system is composed of a door motor control device, car door motor, door drive and linkage device, door, door knife and door lock, door closing protection device, in-place switch, and deceleration switch. In order to ensure the safe, reliable, and smooth operation of the elevator, it is very important to regularly maintain the protective devices in the elevator doors and the switches in place.

Differences between limit switches, travel switches and proximity switches

Are travel switches, limit switches, and proximity switches just a name? Is there a small difference between the three of them, and will this small difference affect our selection? Do you understand? Next, we will switch from the role of the trigger mode and product applications to analyze the role of travel switches, limit switches, proximity switches, and the difference between the three.
