The model 910.70 has been developed specifically for the display of sensors with a 4 … 20 mA output signal in industrial environments.
The design of the indicator with dial and case matches that of a mechanical pressure gauge. The standardised input signal of the indicator enables the connection of a variety of sensors, irrespective of their measurand (e.g. pressure, temperature or flow).
For demanding applications, e.g. with high medium temperatures and critical media, the model 910.70 can be used in combination with a diaphragm seal system, consisting of a pressure sensor and diaphragm seal.
After the connection to the voltage supply, the independent initialisation of the indicator is carried out.
The green LED indicates the readiness for operation. If the LED flashes red, the output signal is either above or below the scale range. In the event of a loss of current, the LED goes out and the pointer drops below the scale.
The model 910.70 offers an optional 4 … 20 mA output signal for the transmission of process values to a control room. This analogue output does not need any initialisation and gives the corresponding value as a 4 … 20 mA signal.
