The high accuracy of the 2-channel digital display E1931X402 makes it suit for weighing as well as statical force measuring or to monitoring loads on machines. Measurement values and the status of the relay-outputs are presented on the digital 5-digit display. The keys and logical input allow to choose between the values coming from channal A and B. It is also possible to link the channels with a mathmatical operation (A+B, A-B, AxB, A/B or k-(A+B)). The calculated value can be displayed as channel C. The optional interfaces offer the possibility to transmit the value for further interpretation. All strain gauges with an output signal of 0/4...20mA 2- or 3-wire as well as 0...10V can be connected. The internal sensor supply can is 18 VDC max 90mA. Usually the customer connects the display it to the force transducers and also adjusts it. The programming is done menu-guided via the keys. It is possible to assign functions like tara, print and so on to the 3 programmable keys. The serial interface allows to retrieve and to set values and parameters. The optional 2 or 4 relays allow to monitor overtraveling and underrunning of limit values. The optional freely programmable analog output offers a 0/4...20mA output signal for analog interpretation. Filters allow to zero interfering signals.
