1. product introduction



YGM409 was a kind of product that could show the temperature and humidity according to the use conditions of the clean factory. The product was installed with a steel drawn board and a sound and light alarm function. It could be installed to the wall with a double 86 type dark box. The product could display 2 factors including temperature, humidity and dew point at the same time.





2. technical data



The display range was from -999 to 9999 (the display resolution is 0.1 degrees centigrade; the range can be set by pressing the button within the display range)

The measurement precision: 0.2%FS

Signal input: current input: 4 to 20mA, pressure input: 0 to 10V

Signal output: current output: 4 to 20mA (three wire system); The electric load was no more than 500

The power output mode was 0 to 10V (three line system) and the electric load was more than 10K. (Note: when the user chooses the type, please pay attention to it. First of all, the power of both ways should be the same. Either of them was 4 to 20mA, or both of them were 0 to 10V. Second, the power of these two ways must be the same. For example, the power of both ways should be from 4 to 20mA, then the power of both of them should also be from 0 to 10V.)
