SRT-77 Process Meter

Brand: SIMEX sp. z o.o.

The SRT-77 temperature meter has one input: thermoresistance: Pt100/500/1000 or thermocouple: K, S, J, T, N, R, B, E.

Measurement is linearised by the polynomial characteristics.

The device with thermocouple input has additional measurement range: -10...90 mV, mainly for diagnostics of measurement circuits.

The main advantage of regulator are two rows of display.

The first one presents measuring value, second one - programmed values: max and min. 1 or 2 relay - or OC, outputs make it possible to control heating / cooling processes.

The RS-485 enables data transmission in production process monitoring systems.

The REL / OC control outputs can adjust the level of measured signal and are controlled according to one or two threshold values.

The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
