C7046A,B,C,D

Air Temperature Sensors

APPLICATION

The C7046 series of Air Temperature Sensors function as

primary and/or secondary sensors in electronic control

systems.

FEATURES

• C7046A,C Sensors have probe lengths of 8 in.

(203 mm) and nominal sensor resistance of 3000 ohms

at 77°F (25°C).

• C7046B Sensor has probe length of 6 in. (152 mm) and

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).

C7046A,B,C,D AIR TEMPERATURE SENSORS OPERATION AND CHECKOUT Operation The C7046D Air Temperature Sensor consists of a platinum thin film sensor element mounted in a tubular probe. It can be applied at various locations throughout single zone and multizone duct systems. The positive temperature coefficient (PTC) characteristics of the platinum thin film element causes its resistance to increase as the sampled air temperature increases.
