Description

Analogue measuring instruments as a display for the panel mounting or as a large display E1930 are well suited for numerous applications because of their accuracy and being easy to read. Measured values and the status of the relay outputs are shown on the 5-digit digital multi-function display. The measuring instruments also offer a totalizer as well as Min/Max memory.

The connection to the corresponding force transducer and the parameterisation are usually performed by the customer for this model. Programming the instrument is menu-driven. All force transducers with an output signal of 0/4 ... 20 mA 2- or 3-wire as well as 0 ... 10 V can be connected. Up to two different sensors can be connected at a time. The internal sensor supply is DC 24 V.

Industrial mV/V measuring instruments, large display or display model E1931

Requests and parameterisation of different values are possible by way of the optional serial interface. The optional 2 or 4 relays allow the monitoring of falling below or exceeding limit values. In addition, a 0/4 ... 20 mA output signal is available for analogue evaluation. Interference signals can be eliminated by filter setting options.
