SENSOR NO.

DESCRIPTION OF SENSOR

 

 

Series DT-420

The smallest silicon diode Temperature Sensor

available. Installs on flat surfaces. Same silicon

 

chip as Series CY-7 and DT-471.

 

 

Series DT-450

Silicon Diode Miniature Temperature Sensor. Same

silicon chip as CY-7 designed to install in recesses

 

as small as 1.6 mm dia. by 3.2 mm deep.

 

 

Series CY-7

Silicon Diode Temperature Sensor. Repeatable,

interchangeable, accurate, wide range, customized

 

for cryogenics.

 

 

Series DT-471

An economical version of the CY-7 for applications

where temperature measurements below 10 K are

 

not required.
