The vacuum transducer is measuring total pressure in the range of 0.1 - 200 mbar.
It can be connected to display and control units or to customer related power supply and evaluation units.
The output signal has a linear dependence on pressure over the whole range.
DI series transducers have a 4 - 20 mA signal output, DU series transducers have a 2 - 10 V output.
The transducer is equipped with a capacitive ceramic sensor and compensated for temperature drift.
Sensors of DI200 and DU200 transducers are equipped with a FPM o-ring sealing,
sensors of DI201 and DU201 transducers use EPDM as sealing material.
The transducer can be mounted to suitable flange connectors or by means of the G1/4 female thread.
The DI200 serves exclusively to provide total pressure measurements in the range 0.1 - 200 mbar.
It may only be connected to cmponents specifically provided for such purpose.
The DI200 is classified in electromagnetic interference class A and therefore can cause radio interference in living quarters.
The transducer can be connected to suitable Leybold display units. For DU series transducers display units of the DISPLAY and CENTER series are available.
Measurement Principle
The DI200 vacuum transducer has an internal capacitive ceramic sensor. Under the influence of pressure a thin diaphragm is bent, on the back of which a capacitor is applied. The bending results in a change of capacity, which is a measure for the applied pressure.
