The transducer is measuring relative pressure in the range ±1000 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. 

The transducer can be mounted to suitable flange connectors or by means of the G1/4 female thread.

The DI2001REL serves exclusively to provide relative pressure measurements in the range ±1000 mbar. 

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

The DI2001REL is classified in electromagnetic interference class A and therefore can cause radio interference in living quarters.

Measurement Principle 

The transducer has an internal piezoresistive ceramic sensor. 

Under the influence of pressure a thin diaphragm is bent, on its 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.
