2.2 Device description

The pressure gauges are designed solely for the direct measurement of process pressures and indirect level measurement in straight, symmetrical tanks. In addition to the main measuring parameters, it is also possible to measure the sensor temperature.

The device can be operated "on site" using a push button on the converter electronics (zero point, measurement span start and span end) or using the optionally available LCD display with four push buttons.

Depending on the measuring range and overload resistance, piezoresistive or thin film sensors may be used. The pressure is transmitted either directly or by way of a separating diaphragm and a liquid fill to a measuring diaphragm, which then distorts and reverses under the applied pressure. The measuring diaphragm features RTDs that change their resistance value based on the mechanical distortion, enabling the applied pressure to be inferred.

Communication takes place via an analogue 4...20 mA current signal in 2-wire technology.

The measuring device is supplied ready for operation. The factory settings for the operating data correspond to your order specifications.

DEVICE DESCRIPTION 2

The following versions with retracted diaphragm are available:

• Compact version with analogue output 4...20 mA

• Compact version with analogue output 4...20 mA and optional LCD display

Versions with flush mounted diaphragm are pending.
