Bamo Pressure Measurement for Gauges is actuated instantaneously; the hysteresis is short, about 0.5%. They may not be use when there are vibrations on the process or with aggressive ambient conditions. They must be used in a dry (not filled) pressure gauge case.
Bamo Pressure Measurement for Gauges Application:
A pressure gauge with one or two contacts is an easy solution to have at the same time a permanent reading of process pressure with a survey of limit pressure over ranges. The pressure indication is done on a 100 mm or a 160 mm dial pressure gauge (up to 4 contacts). The contact is actuated as the pressure index come over.
Magnet Switches
They are suitable for most of applications, even with weak vibrations. The switch actuates with the help of a spring for a quick release. They must be used in a dry (not filled) pressure gauge case.
Inductive Switches
These switches do not have electrical contact, as per standard DIN 19234. They have a greater life than the magnet switches and a better accuracy. They can be used with silicone filled cases. The output signal reflects the location of the pressure index inside the magnetic field of the switch.
