The two-wire system of the pressure sensor is relatively simple, one wire is connected to the positive pole of the power supply, and the other wire is the signal line through the instrument.

How to use the emergency stop button 1. When there is an emergency on the scene, press and lock the red mushroom head button switch or round button switch; 2. Use the safety lock to lock the emergency stop button cover. The role of the emergency stop button 1. Make the machine in any case, immediately ...

Depending on how the actuator acts, there are three most common types of emergency stop switches. Pull Release: Push in the actuator to stop and release by pulling the actuator backwards. Torsional Release: Push the actuator in by torsional actuator to stop and release. Key Release: Perform ...

1. For example, if an emergency stop switch is installed on some machines, then when the machine fails or is in danger, we can cut off the power supply and stop the operation of the equipment through the installed emergency stop switch, so as to protect the safety of people and equipment. The emergency stop switch is usually manually controlled ...

1. Action time The time from closed to open of normally closed contact is much shorter than the time of normally open contact from natural state to closed, which is particularly important when emergency stop is required in the event of danger.

1. High precision, fast response speed, wide range of linear features, good repeatability of use, high signal-to-noise ratio of detection signal, due to the mass production of optical fiber, low price, can be widely used. 2. The optical fiber is made of dielectric material quartz, which transmits optical signals, so it is safe ...

There are two measuring principles for fiber optic sensors. (1) The principle of physical optical fiber sensor, which uses the sensitivity of optical fiber to environmental changes to convert the input physical quantity into a modulated optical signal. Its working principle is based on the optical modulation effect of optical fibers, i.e. the optical fiber ...

According to the modulation form of the light measured object, it can be divided into: intensity modulation type, polarization state type, phase type and frequency type; According to whether the light interferes or not, it can be divided into: interference type and non-interference type; Depending on whether it is possible to continuously monitor the measured as the distance increases, it can be divided into ...

Insulated from dirt, magnetic, sound, pressure, temperature, acceleration, gyroscope, displacement, liquid level, torque, photoacoustics, current, fiber optic sensors can be used for displacement, vibration, rotation, pressure, bending, strain, velocity, acceleration, current, magnetic field, voltage, humidity, temperature, sound field, current...

There are three basic components of a fiber optic sensor network, one of which is called a single-point sensor. An optical fiber only plays the role of transmission here, and the other is called a multi-point sensor, where an optical fiber strings many sensors together, so that many sensors can share a light source to achieve networking.

1. Fiber optic gyroscope Fiber optic gyroscopes can be divided into interference type, resonant type and Brillouin type according to the principle, which is the representative of the three generations of fiber optic gyroscopes. The first generation of interferometric fiber optic gyroscopes, which is now mature and suitable for mass production and commercialization; The second generation of resonant fiber optic gyroscopes, ...

peculiarity 1. Because the prism is used in the reflector, its detection performance is higher and more reliable than that of the general reflective light-controlled sensor 2. Compared with the detached photosensor, the circuit connection is simpler and easier. 3. The design of the child and mother buckle is embedded, and the safety ...

High sensitivity Lightweight and flexible, easy to install and buried Electrical insulation and chemical stability. Optical fiber itself is a highly insulating and chemically stable substance, which is suitable for harsh environments such as high-voltage isolation and flammable and explosive in power systems and chemical systems Good security ...

1. Fully automatic calibration When the workpiece enters the sensitive area of the probe, hold down the "SET" button for 3 seconds, the sensitivity value will be set and displayed in green 2. Two-point calibration When the workpiece is not in the sensitive area, hold down the "SET" key for three seconds, there is a ...

1. There is no display on the digital display after connecting the power supply (1) Check whether the power cord is broken and whether the plug contact is good. (2) Whether the power fuse of the digital display meter is blown. (3) Whether the power supply voltage meets the requirements. 2. The digital display table does not count (1) Passing ...

General Notes: 1. Avoid pulling, squeezing or twisting the optical fiber cable, do not pull when trying to unwrap the entangled optical fiber cable, you need to be patient and careful to untie it at this time. 2. Avoid sharp bending radius (>50mm) of optical fiber cable. 3. When the conduit is removed from the fiber optic signal demodulator ...

1. High sensitivity, 2. The geometry has multi-faceted adaptability, and can be made into optical fiber sensors of any shape; 3. It can manufacture devices that can sense various different physical information (sound, magnetism, temperature, rotation, etc.). 4. It can be used for high voltage, electrical noise ...

1. Prevent the debris from being deposited in the catheter and the sensor from coming into contact with corrosive or overheated media. 2. When measuring gas pressure, the pressure intake should be opened at the top of the process pipeline, and the sensor should also be installed in the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process pipeline. ...

1. It is directly used for the determination of various pressures: air pressure, water pressure, hydraulic pressure (including water pressure), various blood pressure measurements of people in life, etc.; 2.
