GNL-400 process trace hydrogen analyzer adopts imported high-performance electrochemical sensor with latest micro computer technology. It has such functions of LCD display, upper & lower alarm, signal output and relay contactor alarm output. And can be used to measure the hydrogen concentration in air, nitrogen, oxygen and argon.

 

2. Features:
1.Latest trace hydrogen tester 
2.Big LCD screen, concise menu 
3.Connecting to the printer to print the hydrogen concentration in a certain terminal
4.Automatic data storage in a certain interval time, and browsing data at any time
5.It can achieve two-way communication by connected to a computer via the standard RS232 interface
6.Setting upper and lower alarm values arbitrarily during the measurement range. 
7.Calibrating by standard gas
8.0-10mA or 4-20mA electrical current output

Basic PLC Ladder Programming Examples 23

Basic PLC Ladder Programming Examples 23 Basic PLC Ladder Programming Training Examples for Beginners.    Hi friends, here we are starting unique a series of Free Training on PLC Ladder Programming & tutorials. These PLC Ladder Programs are important to learn basics of Ladder programs. Example 7: Sequential control If we serially connect the normally closed contact of Y2 in example 5 to the circuit of Y1 as an AND condition for Y1 (as the diagram in the left hand side), the circuit can not only make Y1 as the condition for Y2, but also allow the stop of Y1 after Y2 is enabled. Therefore, we can make Y1 and Y2 execute exactly the sequential control Example 8: Oscillating circuit The ladder diagram above is a very simple one. When the program starts to scan the normally closed contact Y1, Y1 will be closed because coil Y1 is Off. When the program then scan to coil Y1 and make it On, the output will be 1. When the program scans to the normally closed contact Y1 again in the n...

Augmented and mixed reality: what is it, and where is it going?

XR is a term that has become more prominent in the last few years. It encapsulates virtual, augmented, and mixed reality topics. The definition of each of these has become saturated in the past decade, with companies using their own definitions for each to describe their products. The new IDTechEx Report, “Augmented, Mixed and Virtual Reality 2020-2030” , distils this range of terms and products, compares the technologies used in them, and produces a forecast for the market next decade. This premium article discusses AR (augmented reality) and MR (mixed reality) in more detail. The report discusses 83 different companies and 175 products in VR (virtual reality), AR (augmented reality) and MR (mixed reality) markets. This promotional article specifically discusses the findings from this report of the augmented and mixed reality markets. Augmented Reality (AR) and Mixed Reality (MR) are two technologies which have become more prominent in the past ten years. AR is the use...
