Description

The OS1580 Series has been superseded, please see the OS4000 Series as a possible substitute or consult OMEGA's Temperature Engineering department.

The OS1581 Ultra High Speed Infrared Pyrometer with the DP1581 console was developed for temperature measurements of high speed rotating turbine blades used in power plants and in jet engine test stands. However, it is usable for any temperature measurement requiring time constants on the order of 3 µsec.

A flexible fiber optical cable from the detector terminates with a lens in a probe for remotely viewing the target area. Since there are no electronics in the probe, it is immune to electrical noise, radiation fields and, to a large extent, mechanical vibration.

The small size of the probe and flexibility of the fiber optical cable allow viewing of the target in inaccessible tight locations not possible with conventional line of sight optics.

A vacuum bushing allows measurements down to 10^-7 Torr.

Temperatures of targets as small as 0.004" can be measured over a 3:1 temperature section of the full system range with an optical cable up to 30' long.

The outputs are: average (T=3 µsec), average peak (T rise= 3 µsec, T decay= 2.4 msec), maximum peak (T rise= 3 µsec, T decay= 72 msec).

The monitor is mounted on a 19" rack panel that can be placed in an optional NEMA-4 enclosure.
