Duct temperature transmitters

The TDTH transmitter offers 8 selectable temperature ranges in one unit, adjustable via jumpers on the PCB:

• -20°C to +150°C
• -50°C to +50°C
• -20°C to +80°C
• -30°C to +60°C
• 0°C to +40°C
• 0°C to +50°C
• 0°C to +100°C
• 0°C to +150°C
  Other temperature ranges are available upon request.

The TDTH duct temperature transmitter is powered by 15-36 Vdc for the 4-20 mA output or 24 Vac/dc for the 0-10 Vdc output. It uses a PT1000 sensor (DIN EN 60751, class B) to ensure precise and reliable temperature measurements.

The sensing element is located at the end of the probe, allowing for accurate air temperature detection. The standard probe length is 200 mm, with additional options of 50, 100, 150, 250, and 300 mm available upon request. The probe is constructed from high-quality steel for durability.

Housed in a robust IP65-rated ABS plastic enclosure, the TDTH transmitter features 4 quick-locking screws for secure access. Wiring is connected via a terminal block inside the enclosure, and it includes a plastic cable entry gland with strain relief for added protection.

The TDTH transmitter is available with or without an LCD display. The LCD display provides real-time temperature readings in degrees Celsius, offering added convenience for users.

The TDTH duct temperature transmitter is supplied with a duct mounting flange, ensuring fast installation and effective sealing into the duct system.

The TDTH duct temperature transmitter is a reliable, flexible, and high-performing solution for air temperature monitoring in HVAC and industrial applications.
