NEW 2-COLOR IR THERMOMETER: 80 MICROSECOND RESPONSE TIME

Response speed of two-color infrared thermometers is no longer limited to the millisecond domain.

Metis-Head-rtop

Franklin Lakes NJ, USA — ??Process Sensors Corp???s newly released, self contained, Metis HQ11/HQ22 non-contact infrared temperature sensor easily captures 12,500 measurements per second with an unprecedented 80 microsecond response time.

With a temperature span of 350 ??C to 2500 ??C, the two new models in the HQ11/HQ22 Series are ideal for applications in high-speed ferrous and non-ferrous metals processing, ceramics and semiconductors, as well as demanding research and development environments where short duration phenomena need to be monitored.

Target spot sizes of 0.5 mm to 23 mm diameter are offered in the same two models, utilizing either standard focusable optics or focusable lens fiber optics.

As with all Metis two-color models, the HQ11 and HQ22 can also be used as single wavelength pyrometers. In the switchable single wavelength mode, operators have the choice of obtaining output signals from shorter or longer wavelengths, or both via analog and serial communication ports.

Operators also have a choice from three methods of optical alignment and focusing onto a target: through lens sighting, laser aiming, or an integral color video camera for monitoring the target area in harsh or difficult to access locations.

A peak picker function can be programmed to capture and hold the highest temperature measurement when targets are sporadically obscured by dust, steam or surface scale.

Switchable, analog 0-20 mA/4-20 mA outputs connect with process control or data acquisition equipment. A fast digital RS485, 921 kBd maximum communications interface is also included.

The free of charge PSCWin software allows simple set up of thermometer parameters and facilitates the recording of data in graphical, text or tabular format.
