Tecsis — Digital Displays: with Microprocessor (mV/V) E1930

Digital displays are used to present sensor signals. The 5-digit LED-display of the model E1930 series shows values measured by sensors. It is designed for panel-mounting. Optional there is a wide range of interface-extensions to link controls available. The model E1930 series can be equipped with 2 or 4 relay-outputs, an analog output and a serial interface.

Application

The high accuracy of the digital display E1930 makes it suit 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. All strain gauges (max 4 sensors with 350 Ohm Parallel) with an output signal up to max ±4,8mV/V respectively ±48mV/V can be connected. The internal sensor supply can be 5 or 10 VDC. Usually the customer connects the display it to the force transducer 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.
