2 Description

The CM miniature infrared sensors are high performance noncontact infrared
temperature measurement systems. They measure the amount of energy
emitted from an object accurately and repeatedly and convert the energy into
temperature signal.

The following analog outputs are available by different model:

0 to 5 Volt
J thermocouple
K thermocouple

The LED on the back of CM shows the status of units.

3.2 Optical Diagram

The optical diagrams indicate the target spot diameter at any given distance
between the target object and the sensing head.
All target spot sizes indicated in the optical diagrams are based on 90%
energy.

Optical resolution 13:1 @ 150 mm (90% energy)

Figure 1：Optical diagram

Calculating the Target Spot Size

To calculate the target spot size from two known points within an
optical diagram the following formula can be used:

Sx = unknown diameter of target spot
Sn = smallest known diameter of target spot
Sf = greatest known diameter of target spot
Dx = distance to unknown target spot
Dn = distance to smaller known target spot
Df = distance to greater known target spot
