Explanation
TR3 is a microprocessor based transmitter that processes strain gauge signals for industrial use.
It is used as a signal converter for PLC or similar industrial control devices in weighing, dosing, level control and process control applications. With an adjustable relay output, it is possible to control stand-alone automation systems, such as on-off, fill-empty.
The rail mounting housing forms integrity with other panel components and facilitates connections.
The device, designed for industrial environments, offers three-way galvanic isolation. This eliminates the risk of damage to strain gauges from leakage currents, and the output stability is not affected by electrical noise. Since all adjustments are made via buttons, the deviations that can occur with potentiometer elements are eliminated.
