DI/DU系列真空计

The vacuum transducer is measuring total pressure in the range of 1 - 2000 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 piezoresistive ceramic sensor and compen sated for temperature drift.

Sensors of DI2000 and DU2000 transducers are equipped with a FPM o-ring sealing,

sensors of DI2001 and DU2001 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 DI2000 serves exclusively to provide total pressure measurements in the range 1 - 2000 mbar.

It may only be connected to components specifically provided for such purpose.

The DI2000 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.

The DI2000 vacuum transducer has an internal piezoresistive ceramic sensor.

Under the influence of pressure a thin diaphragm is bent, on it's back a resistor bridge is applied.

The bending forces the measurement-bridge to come out of tune, which is a measure for the applied pressure.
