LBBDCH
Temperature range: 50°C to 500°C
Extended area black body is defined by the large emitting surface area precise temperature control with good uniformity. Tempsens make Blackbodies are state of the art, highly accurate and stable with different standard sizes and temperature ranges. The LBBDCH Series Extended Area black bodies are low temperature infrared reference sources operating either in absolute or differential mode.
Description
The LBBDCH Series Extended Area black bodies are low temperature infrared reference sources operating either in absolute or differential mode. This Black body series featuring the very high stability, they are particularly well adapted for t h e characterization and performance validation of a very wide range of IR Sensors, such as high resolution cameras for Thermography and long range thermal imagers. Essentially the black body emits a known amount of energy for an infinite number of wavelengths. This enables to draw the expected black body radiation curve for a given temperature. Temperature is accurately controlled by High accurate PID self tuning controller.
Key Features
- Wide Temperature Range: LBBDCH offer a temperature range from 0°C to 115°C for absolute temperature and -25°C to 90°C for differential temperature range.
- Large Emissive Area: LBBDCH has the large emitting surface area precise temperature control with good uniformity. It is available in the customize sizes.
- High Emissivity: The LBBDCH Exceptionally high emissivity of 0.95 ±0.02. Extremely quick to reach various temperatures, i.e. heats up from room temp to +50°C in 15 minutes.
- Accuracy and Performance: The LBBDCH is high stable unit that also provides excellent calibration accuracy with stability.
- Computer Interface: The communication port (USB) enables communication with selected LBBDCH calibrator.
User Interface
The Temperature Control window opens in either the Absolute or Differential working modes.
Absolute Mode : In absolute mode there will be temperature indication for Emitter plate and target but no temperature difference will be shown. We can control only emitter temperature.
Differential Mode : In differential mode we can change temperature difference between emitter and target needed. We have to put delta T value as set point. Controller will automativally change emitter temperature to achieve desired delta T value.
