Details

The pyrometer IS 140-PB is a digital, highly accurate pyrometers with Profibus-DP interface for non-contact temperature measurement on metals, ceramics, graphite etc.

The PB types are equipped with a Profibus-DP interface. They can easily be integrated in existing Profibus systems. As part of standard delivery, the GSD file (Profibus) offers a selection of 5 different module configurations for varying requirements. The project planning can be done with any project tool.

For optimal match of the instrument to the application, 3 different focusable optics with extremely small spot sizes are available.

The pyrometer parameters can be selected via the integrated key pad, the settings are indicated on the built-in LC-Display. In measuring mode the actual temperature is indicated.

A laser targeting light, a thrulens view finder or a color camera module (for standard versions only) for exact alignment of the pyrometer is available. The color camera module enables the optical alignment of the pyrometer to the measuring object via video screen or monitor.
