nominal sensor resistance of 22,800 ohms at 77°F (25°C).
• C7046D Sensor has probe length of 8 in. (203 mm) and
nominal sensor resistance of 1097 ohms at 77°F (25°C).
• Carbon type, negative temperature coefficient
(NTC) thermistor sensing element in the C7046A,B,C
and platinum thin film, positive temperature coefficient
(PTC) element in C7046D precisely measures
temperature changes.
• No settings or calibration required.
• Solid state components not affected by dust or dirt.
• Fast reacting.
• Rugged stainless steel insertion probe.
• Mounts on duct or plenum surface with mounting
flange or in a 2 in. by 4 in. (51 by 102 mm) junction box.
• C7046B can be used as a replacement for C7100B
Averaging Temperature Sensor where duct or plenum
cross section is less than 13 in. (330 mm).
