Normalizing amplifier – Amplifier TR 3
The TR3 transmitter is a microprocessor-based device designed to convert signals from strain gauges. They are used in dosing and weighing control together with a PLC or similar devices. Performs the task of automating unloading and loading, opening or closing shutters. Equipped with one adjustable relay output. Mounted using a DIN rail.
Three-level galvanic separation protects against current leaks, reduces the possibility of errors from parasitic signals. The device is configured using button control.
The transmitter of this model is used in industrial conditions.
Features of the TR3 transmitter:
- Three-level galvanic separation
- Zero setting in the range up to 50% of the total scale
- Error indication in case of voltage overload
- Indication of the state of the relay contact
- Analog current and voltage output
