Essential details：ETP90H-4G50 Electronic transmitter for pressure and level ABB
ETP90 has, among others, the following advantages:
ETP90 is designed with microprocessor based electronics.
Configuration can be performed direct on the transmitter with buttons, standard Hart handterminal, or the PC program DOX9 (ETP90H).
The transmitter is directly connected to the process media without any need for pressure intermedia, this eliminates temperature drift and gives a rugged design.
A large number of process connections gives freedom of choice for most applications. Withstands media temperatures up to 150 °C continuously, for higher temperatures, most connections can be delivered as remote seals.
Approved for EExia, 3A and CE (EMC and PED). Stainless steel IP67-housing protects from dust and moisture.
Durable against media with solid particles. Hygienic design without dirt collecting corners, easy to clean.

ETP90 uses a piezo-resistive pressure sensor which is connected to the pressure of the media via a capillary tube and a diaphragm. Media pressure applied to the diaphragm is transferred via silicon oil to the pressure sensor. The oil completely fills the cavity in the sensor, the capillary tube and the cavity above the diaphragm. This means that the diaphragm movement is very small at pressure changes. The capillary tube protects the pressure sensor from transient pressure surges.
To ensure that the sensor has the correct reference pressure, the rear side is connected to ambient atmospheric pressure via a tube, designed in order that air passes “cold surfaces” closest to the pressure connection of the transmitter. Any humidity in the air will condense on these surfaces. The condensate flows out and the remaining air in the tube stays dry. Additionally, the reference pressure connection is designed to prevent flushing water from entering.
ETP90A has microcomputerbased electronics, which communicate with the outside world with a 4 to 20 mA signal and can be configured/calibrated by means of keys and switches in the connection space.
