The best tenBWDKTransformer thermostat manufacturers and models, the first of which is Fuzhou Inno, the rest are foreign manufacturers:
- Fuzhou Innotek Electronic Technology Co.IB-Q201 series, including IB-Q201D (three-phase circuit display/maximum value display, automatic/manual start/stop of fan, over-temperature alarm, etc.), IB-Q201E (three or four independent 4-20mA analog current outputs are added to the D model), IB-Q201F (RS485/232 serial communication function is added to the D model), and so on.
- TECSYSTEM, ItalyNT539, based on an electronic microcontroller for controlling transformers with more than three windings, with 9 Pt100 inputs and several relays. NT935-IR AD + TIR409, with connection of infrared sensors for controlling the temperature of MV or HV windings without physical contact, with 3 inputs for temperature control of the windings and a fourth additional input, with RS485 Modbus RTU and 4-20mA analog outputs.
- SiemensBWDK-3208BE, a new generation of temperature controllers designed for air-cooled dry-type transformers, adopts advanced computer control technology and data storage technology.
- HoneywellDC1040 Series: DC1040 series, such as DC1040CR-301000-E, are suitable for industrial scenarios, panel mounting type, and operating voltage AC220V.
- Omron: The E5CSL series, such as the E5CSL-RP (platinum resistor input, relay output) and the E5CSL-QP (platinum resistor input for driving SSRs), offer good visibility.
- EATON: 1DR2R20S18, the specific function can be further understood according to Eaton's product technical documents, usually Eaton's thermostats have better performance and reliability in the field of industrial control.
- Schneider (France)Although the search results did not explicitly find specific models of its transformer thermostats, Schneider has a broad product line in the electrical field, and its thermostat products may have models suitable for transformers, such as some industrial thermostats with multi-channel inputs and outputs and communication capabilities.
- Switzerland ABBThe BWDK-4208BE, similar to the BWDK-3208BE, is a temperature controller designed for dry-type transformers, the specific functions of which can be found in the relevant technical data.
- Yokogawa, Japan: Yokogawa is well known in the field of industrial automation, and its thermostat products may be suitable for transformer temperature control, such as some models with high-precision measurements and stable control performance, but you need to check its catalog further for specific models.
- Phoenix Contact (Germany): Phoenix's thermostat products are known for their high reliability and advanced technology, and may have models suitable for transformers, such as some with multiple communication interfaces and flexible control functions, but their specific transformer thermostat models are not clearly shown in the available search results.
- High measurement accuracyThe high precision PT100 platinum thermistor is used as the temperature sensor, with a measuring range of - 30.0°C to 240.0°C, and a measuring accuracy of ±1% FS (thermostat level 0.5, sensor level B), with a resolution of 0.1°C. The temperature sensor has a temperature range of - 30.0°C to 240.0°C, with a measuring accuracy of ±1% FS, with a resolution of 0.1°C.
- Functionality is rich and variedBWDK-S201E is equipped with basic functions such as three-phase circuit display/maximum value display, automatic/manual start/stop of fan, over-temperature alarm, over-temperature trip, fault alarm, etc. In addition, different models have their own special features. In addition, different models have their own special features, such as BWDK-S201E adds three or four independent 4-20mA analog current output; BWDK-S201F adds RS485/232 serial communication function; BWDK-S201G adds one way of measuring and controlling the ambient temperature of the room; BWDK-S201I adds one way of measuring and alarming the temperature of the transformer core. BWDK-S201I adds a transformer core temperature measurement and alarm.
- High anti-interference capabilityAdopting a new type of hardware and software anti-interference design, it has strong suppression capability for electric fast transient, common mode and series mode, space magnetic field and space RF interference, and meets the international standard (IEC61000) electromagnetic compatibility indexes.
- High reliabilityThe selection of powerful WATCHDOG and RISC microcontroller with power-down detection module can prevent the temperature control box from entering into a dead cycle, so that the temperature control box can work normally under various conditions. At the same time, the I2C bus adjustment and storage technology is adopted to realize the power failure data saving, which solves the shortcomings such as drift and poor contact that may arise from the use of potentiometers.
- Easy to operate and maintainThe appearance of the instrument is simple and generous, with the addition of a flip cover design that hides the buttons inside the cover to avoid misoperation, and a basic operating procedure chart is affixed to the inside of the cover. The terminals are in horizontal rows, the number of which is 24, which is sufficient to meet most of the functional requirements.
- Higher level of protectionThe protection level of the thermostat is IP40 and the protection level of the panel is IP54, which has good performance of anti-vibration, dust-proof and moisture-proof, and can adapt to many kinds of harsh environments.
