  Overview:
This series of dry-type transformers temperature controller is designed for the safe operation of dry-type transformers and development and production of intelligent instrument. The series temperature controller instrument used by the U.S. AD company dedicated microcontroller, embedded in the transformer winding temperature measurement using the hole to measure the thermal resistance of platinum winding temperature and digital display, providing over-temperature alarm winding, winding over-temperature trip and alarm sensor failure function, so you always know the temperature of dry-type transformers operating parameters, you can also start and stop automatically according to the set point temperature of the cooling fan on the winding, effectively improve the dry-type transformers to run the security, reliability and service life. This product also provides RS485 or RS232 communication, with standard bus interfaces and communication protocols can be easily connected with the monitoring system.

Temperature controller is the use of temperature and liquid incompressible liquid thermal expansion and contraction principle and automatic adjustment. When the temperature control fluid temperature increases the thrust produced by the thermal expansion of the media off small, to reduce the output temperature; when the temperature control fluid temperature decreases contraction under the action of the device in reset the media turn up the heat to raise the output temperature , so that the temperature be controlled to achieve and maintain the set temperature range.

Output voltage and current display, easy and intuitive 4. Can be a single point temperature or 50 segments 5 programmable temperature control curve. Built-in alarm buzzer sounds automatically when over-temperature 6. WIN-CT optional temperature control system of specialized software 7. Powerful communications capabilities, easy remote control of five steam temperature controller Working principle: vapor pressure bellows action acts on the spring, the spring will control the board by the control knob, the capillary suction on the air conditioner indoor air outlet, the indoor temperature of return air circulation reacts . When the room temperature set up to adjust temperature, capillary and bellows in the temperature of the gas expansion agent, the corrugated tube elongation and to overcome the spring will turn the switch contacts, when the compressor operation, the system cooling until room temperature When they dropped the set temperature, temperature of the gas contraction, shrinkage and the spring bellows with action will switch off position, so that the compressor motor circuit is cut off. Repeated this action, and thus to control the room temperature. Six, electronic temperature controller electronic temperature controller (resistance) is a method of using resistance to measure temperature, and generally use platinum, copper, tungsten, and semiconductor (thermistor) for temperature resistance, These resistors have their advantages and disadvantages. Most home air conditioners are thermistor type sensors.
Relen seven thermostat, temperature controller, the principle of a mechanical and electronic, and mechanical thermal expansion coefficient using two different metal sub-together, the temperature changes, he will change the curvature when bent to a of degree is on (or off) circuit, making the cooling (or heating) device work. The adoption of electronic thermocouple, platinum resistance temperature sensing devices such as, the temperature signal is transformed into electrical signals through the microcontroller, PLC, control relay circuit makes heating (or cooling) device work (or stop). There are mercury-type thermometer, the temperature to be connected with contacts and mercury (from the empty net HVAC experts companion)
