TR-3 Load Cell Analog Signal Transmitter
Load Cell Analog Signal Transmitter

Overview

Explanation;
Esit TR3, is a micro processor based transmitter that processes the load cells signals to be used in the industry.

It is used as a signal converter for PLC or similar industrial control devices in weighing, batching, level control and process control applications. With a user settable relay output, it is possible to control stand-alone systems of simple on-off, fill-empty automations. The rail-mounting case forms an integrity with other panel components and eases the connections.

The device which is aimed for industrial environments, features a three-way galvanic isolation. This eliminates the risk of breakdowns of load cells against leakage currents and the output stability is not affected by the electrical noises. Since all adjustments are done via keys, the drifts that may be seen with the potentiometric elements are ceased.

Features;

  • Three-way galvanic isolation
  • Internal power supply for current output eliminates need for external power supply
  • Zero setting up to 50% of full range
  • Error indicator in case of over voltage
  • Relay state indication
  • 0-20 mA Current and 10V Voltage output

Options;

RS232
