Stock Code:
SKU: product options
The Gefran 40TB double indicator / Alarm unit provides combined measurement of pressure and temperature in one unit. It is used on extruder lines and in food processing plants.
The 40TB is a temperature and pressure double Indicator/ Alarm unit. Its operator interface is comprehensive and efficient, with two 4- digit displays for the two process variables and engineering units indications. It is also equipped with a red LED bargraph, which can be associated to process variables and to peak values.
Features:
- Inputs configurable from faceplate
