How to choose a safety light curtain?

Time:2022-09-14 Views:


1. Where is the application?

 

Before buying a safety grating, we must first know where the safety grating that we need is used for? We want to make the safety light curtain achieve what kind of effect, etc. After our purpose is clear, we can inform the safety light curtain manufacturer to provide the most suitable light curtain for ourselves.

 

2. Resolution: according to the parts of the body that need to be protected

 

The resolution (R) of a safety light grid is the smallest dimension at which an object can darken the sensing area formed by at least one beam. Resolution depends on geometric properties such as diameter, center distance, etc. to be determined independently of the external and operating conditions of the grating.

 

3. The height of the protected area

 

It is very important to distinguish between "sensing zone height" and "protection zone height". The height of the sensing area of the safety light curtain is the distance from the upper edge of the first beam to the lower edge of the last beam. The protective field height of a safety light curtain refers to the effective protection area where the size of the object is greater than = the resolution of the safety light curtain and this may safely dim the light beam.

 

4. Safe distance

 

The safety distance of the safety light curtain should be such that the operator cannot reach the dangerous area until the movable dangerous machinery is completely stationary:

 

a. Grating response time

 

b. Machine overflow time

 

c. Resolution of the grating

 

d. The approach speed of the object to be detected

 

Of course, another important thing to note is the specific use of safety light curtains. As far as our company is concerned, there are ordinary safety light curtains and measuring light curtains. Ordinary safety light curtains are used to protect human hands, etc. The function of the light curtain is powerful, and it can perform various measurements, detection light curtains, vehicle separation testers, automatic counting and so on.
