SRT-94 Process Indicator for temperature sensors


The SRT-94 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. A 4-digits, 20-millimetre LED display enables seeing of measured values from a distance. The RS-485 enables data transmission in production process monitoring systems. 0, 2 or 4 relay (or OC) outputs make it possible to adjust the level of the measured signal. Every relay output can be controlled according to one or two threshold values.
