Tube resistance furnace installation considerations

A laboratory tube resistance furnace without special installation, indoor and uneven ground or table can be placed. But supporting the controller should avoid vibration, placement and should not be too close to the furnace to prevent overheating and affect the normal operation of the control section.
2 Insert the thermocouple from the even holes, even the gap between the hole and the thermocouple with asbestos rope packing to prevent heat loss.
3 reveal temperature controller enclosure, connect the power cable as standard, electric wire, thermocouple and safety switch wire, because the controller is shared with the Department of furnace line, so the phase and neutral is not reversed, pay attention to the thermocouple connections. "+ "" - "pole can not be reversed, otherwise the instrument will not indicate.
4 would XCT-101 rear connection panel temperature indicator "short" and "short" the connection between the mechanical zero adjustment, if the compensation wire and cold junction compensator, should the mechanical zero adjustment to the baseline temperature point, do not use compensating wires, put the mechanical zero adjustment to the scale zero. However, the indicated temperature is measured points and thermocouple cold junction temperature difference.
5 Check the wiring is correct, cover controller case, the temperature indicator pointer to the required temperature (ie rotating indicator panel lower corner screws) then connect the power, open the control power switch, then the green light is lit. Relays begin work, laboratory tube resistance furnace powered ammeter reading that is produced, the temperature indicator pointer is gradually rising, which means that the laboratory tube resistance furnace with temperature controller are working properly.
6. Laboratory tube resistance furnace heating with constant temperature respectively red, green represents warming, red light indicates thermostat.
