Part number: 4.3151.10.020
Special characters are a defined and optimised, dynamic behaviour as well as:
 High level of measuring accuracy and resolution
 High damping ratio at a small delay distance
 Low starting threshold
 Very low power consumption
 No wear of the potentiometer due to mechanical stress
 Overvoltage and reverse polarity protection

The measuring value is available at the output as analogue signal. The output signal can be transmitted to display instruments, recording instruments, data loggers as well as to process control systems. For winter operation the instrument (4.3151.00.x1x) is equipped with an electronically regulated heating.
