Description

The digital TCF/TPF 100 Series process pressure and fill level transmitter in a reliable stainless steel field housing with piezo-resistive or thin-film DMS measuring principle can be programmed via three pushbuttons and a display/control panel without pressure requirement at the measuring location. The quick calibration of the zero point and measuring range via two buttons has proven to be a real advantage especially for applications in the field of fill level measurement. The digitized output signal is an imposed continuous current that is linearly proportional to the input pressure.

It is also possible to display various pressure units during operation as well as the display of the process (sensor) temperature as a secondary process parameter. The display and control panel is either integrated in the field device where it can be accessed by unscrewing the front ring (360° rotatable, removable) or is available as an external housing with plug connector. The transmitters are then delivered without graphic display (cost saving per measuring location).

The pressure sensor is isolated from the substance to be measured by a stainless steel membrane. The pressure transfer is made via a foodstuff-safe oil filling. All membrane contacting parts are welded. The sensor-specific values are stored in a characteristic data memory and are available to the microprocessor for analyses. All Hengesbach pressure transmitters are temperature compensated. An additional temperature sensor as a secondary measuring element is used to show the temperature measured on the sensor as additional information on the display.
