Summary
|
|
Bimetallic indication thermal resistance (thermocouple) is an integration temperature measurement instrument with on site indication and remote transmission display function.It can be used directly to measure the temperature of gasses、liquids and substances. The indication value can be read distinctly on site.And the signals can be transmitted to the control room.The transmitted signals include Pt 100,K type and E type thermal resistance signals,also the (4~20)mA standard signal after transmission. It plays a role as an instrument with two functions |
