SWITCHES FOR GAUGES
|
|
SWITCHES FOR GAUGES,
APPLICATIONS
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.
|
The contact 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.
Technical features
Nominal voltage: 250 V, as a maximum
Release or priming current: 0.7 A as a maximum
Load current: 0.36 A as a maximum
Switching power: 10 W as a maximum
Contacts: Ag 80 / Ni 20
Accuracy: 0.5% F.S.
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.
Technical features
Nominal voltage: 250 V, as a maximum
Release or priming current: 1.0 A as a maximum
Load current: 0.6 A as a maximum
Switching power: 30 W as a maximum
Contacts: Ag 80 / Ni 20
Accuracy: from 2 to 5% F.S.
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.
