Simex SRT-94 LED Display

Simex SRT-94 LED Display

Quick Overview

The SRT-94 temperature meter has a Pt100/500/1000 input with automatic recognition of 3 and 4-conductor connection and features full linearization of characteristics. 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. 2 or 4 relay (or OC) outputs make it possible to adjust the level of the measured signal. The relay outputs can be controlled according to one or two threshold values.
