Fig. 24: Influence of the process pressure to the switching point
1 Shifting of the switching point in mm (in)
2 Process pressure in bar (psig)
3 Switching point at reference conditions (notch)
4 Tuning fork
Repeatability 0.1 mm (0.004 in)
Hysteresis approx. 2 mm (0.08 in) with vertical installation
Switching delay approx. 500 ms (on/off)
Measuring frequency approx. 1200 Hz
Ambient conditions
Ambient temperature on the housing
-40 … +70 °C (-40 … +158 °F)
Storage and transport temperature -40 … +80 °C (-40 … +176 °F)
Process conditions
Measured variable
Limit level of liquids
Process pressure -1 … 64 bar/-100 … 6400 kPa (-14.5 … 928 psig)
The process pressure is dependent on the process
fitting, for example Clam p or flange (see the following
diagrams)
Process pressure - Clamp fittings
Ʋ Clamp connection up to 2" -1 … 16 bar/-100 … 1600 kPa (-14.5 … 232 psig)
max. 150 °C (302 °F)
Ʋ Clamp connection > 2" -1 … 0.5 bar/-100 … 50 kPa (-14.5 … 7.25 psig)
> 150 °C (> 302 °F)
Maximum allowable operating pressure 100 bar/10000 kPa (1450 psig) or 1.5 times process
pressure
The function of the instrument is ensured up to an
operating pressure of 100 bar/10000 kPa (1450 psig)
at a maximum process temperature of +50 °C (+122 °F)
(only with threaded versions).
