XMTInstructions for the use of (Series) digital display regulators
First, an overview
XMTSeries digital display regulator has many characteristics, such as high precision, good reliability, easy installation, strong anti vibration, strong anti-interference ability and low price. A variety of optional dimensions, complete control, widely used in plastics, rubber, packaging, food machinery, metallurgy, chemical industry, aquaculture and etc.…A variety of industries, in the use of-200C°~1800CTemperature measurement and automatic control in a certain range, such as with the corresponding sensor, can also be used for pressure, flow, liquid level and other parameters display and control....

Three. Instrument dimensions and opening dimensions are shown in the following table (unit)mm）
< annex >
2 sets of mounting brackets, one manual, one certificate
(phase) foot 220 volts firewire,
(middle) 220 volt line on foot,
The high, the total, the low foot are the outputs, the OUT main outputs
4, 5, 6 feet for second output, AL1 alarm output
1, 2, 3 feet are connected to thermocouple or PT100 and other temperature sensor signals
1 is positive electrode, and 2 and 3 are negative electrode
The control method is divided into two modes of heating and cooling, cooling is divided into air cooling and water cooling, general industrial equipment with single loop heating mode, heating method of electric heating wire and steam heating, electric heating is relatively simple, is achieved by heat resistance, steam heating mode by adjusting the thermostat valve to control the amount of steam.
