Technical data at a glance

10.1.1 Input
The Gammapilot M measures the pulse rate (number of counts per second). This rate is proportional
to the intensity of radiation at the detector. From this rate, the Gammapilot M calculates the desired
measured value:
• Level limt (0% = "radiation path free"; 100% = "radiation path covered")
• Level (in %)
• Position of interface layer (in %)
• Density (unit selectable)
• Concentration (unit selectable)
In order to compensate temperature influences on the density measurements a temperature sensor
PT 100 (4-wire connection) can be connected.
• Measuring range: -40 °C ... 200 °C
• Accuracy: ±1 K
10.1.2 Output
• PROFIBUS PA
• Pulses for cascading mode
Freely selectable, 1 ... 999 s
