Page 4: Function
1. Function The DT7200 family of pressure transmitters can be used for the measuring of pressure in explosive areas. The transmitter has a two-line system; that is, it creates the 4-20 mA signal proportionate with the input pressure in the external power supply circuit. The process medium to be measured can be either gas or liquid. -
Page 5: Operating Principle
3. Operating principle The output of the pressure sensor is a voltage in proportion with the input pressure. This voltage gets amplified by a high-impedance symmetrical amplifier. The amplified signal goes to a voltage-current transformer. This is the place where the 4 mA output current is set as „zero” pressure, and the 20 mA output current is set as the effect of the pressure that corresponds with the end-position of the scale. -

Mounting of the device The transmitter is delivered with a probe-connection in accordance with the customer order. It can be screwed into the threaded connection socket made for this purpose in the system. An open-end wrench (size 32) must be used for to tightening. -

7. Putting the device into operation The transmitter becomes operable after it has been mounted and after its electrical connections are established. (checking of seals!) Supply voltage values higher than those specified in the Technical Specifications may cause damages to the transmitter. After the device has got to its operating temperature (when there are no more temperature drifts;... -
