VCP TDTH - Duct Temperature Transmitters

The duct temperature transmitter TDTH is used for sensing the air temperature in heating, ventilation and air conditioning systems (e.g. in supply air, extract air or mixed air ducts).

Duct temperature transmitters TDTH have 8 different temperature ranges in same unit, selectable via jumpers on pcb:

• -20C to +150C,
• -50C to +50C,
• -20 to +80C,
• -30C to +60C,
• 0 to +40C,
• 0 to +50C, 0 to +100C and
• 0 to +150C.

Other temperature ranges on request.
