SRT-N118 Temperature Display

Description

The Simex SRT-N118 is a high-performance, wall-mounted digital temperature meter designed for precise monitoring in industrial environments. While the SRP-N118 series is tailored for generic process signals (mA/V), the SRT version is specifically optimized for temperature sensors, providing native support for both RTD inputs (PT100, PT500, PT1000) and a wide range of thermocouples (Type K, J, S, T, N, R, B, E). Housed in a rugged IP67 enclosure, it features a large 20mm, 4-digit red LED display and an integrated 24V DC transducer power supply. The unit includes RS-485 Modbus RTU communication as standard and offers versatile output options, including up to two relays for on/off control or an isolated analogue output for signal retransmission. Its advanced firmware allows for full linearization of sensor characteristics and peak value detection, ensuring accuracy and reliability in harsh process conditions.
