Product Preview :
The DZB-30 VER:2.0 ash hopper heater temperature feedback board, an electric heating element , is constructed by inserting a metal resistance wire into a metal tube. The interstices are densely packed with crystalline magnesium oxide, a material with excellent thermal conductivity and insulation properties.
The DZB-30 VER:2.0 ash hopper heater can be bent into any desired shape and can be installed in air ducts to heat air, immersed in water or other liquids to heat water or other liquids, or placed directly in solid metal to heat metal.
Specifications (to be confirmed with supplier):
- Input: Temperature sensor signal (usually RTD or thermocouple type, depending on ESP design)
- Output: Conditioned feedback signal to ESP controller (typically 4–20 mA or voltage feedback)
- Board Version: VER:2.0 (updated revision of DZB-30 series)
- Operating Voltage: Low-voltage DC (commonly 24 VDC or 12 VDC, depending on ESP cabinet design)
- Mounting: PCB with edge connectors or screw terminals
- Protection: Over-temperature alarm and feedback loop to shut down HV supply if unsafe
- Dimensions: Approx. 120 × 80 mm (typical for ESP feedback boards; must confirm exact)
- Weight: ~0.2–0.3 kg (bare PCB with components)
Application:
- Used in Electrostatic Precipitators (ESP) for:
- Power plants (coal, biomass)
- Cement plants
- Steel mills
- Pulp & paper industry
- Ensures temperature monitoring of HV rectifier/transformer oil or cabinet environment to prevent overheating.
