Description

The OS1553 Series has been superseded, please see the OS4000 Series as a possible substitute or consult OMEGA's Temperature Engineering department.

The OS1553-A is a self-contained fiber optic infrared transmitter designed to provide a linear 4 to 20mA output for monitoring, datalogging or controlling temperature.

The detector maybe remotely mounted up to 4' away from the fiber optic lens via the fiber optic cable, removing it from hazardous locations. Other problems that can be overcome by the OS1553-A fiber optic design include: taking measurements in high energy fields measuring very small objects or surfaces; and taking measurements in “dirty” atmospheres containing water vapor, dust or smoke.

Some important factors that will determine the fiber optic assembly needed for your infrared application are: the distance from the fiber optic lens to the surface being measured; the size of the object being measured; temperature range; ambient temperature around the fiber optic cable; the length of the cable; the method of heating the surface being measured; and the atmospheric conditions between the fiber optic lens and product.
