STATIONARY PYROMETERS

Pyrometer CellaTemp^® PA 20CellaTemp^® PA 20 is a digital pyrometer for detecting temperatures ranging from 250 to 2500 °C. The wide-range temperature sensor provides versatility for a variety of applications. The target can be focused either by through-the-lens sighting or with an laser spot light for target marking. The pyrometer features a rear panel display and keypad. Parameters such as emissivity, measuring range or smoothing constant can be adjusted directly at the instrument. The LED display will show parameter adjustments made using the keypad. In the normal operating mode the display indicates the current temperature reading.

Features:

• Range: 250  to 2500 °C
• Digital input / output
• Focusable, interchangeable optics allow for precise distance adjustment 
• Precision lenses with broadband antireflection coating
• LED display is easy to read from a distance
• Test current can be applied to perform diagnostics
• Signal processing: two analogue outputs and USB / RS485 interface

• Range of models
