SRT-77 Process Meter with Thermoresistance and Thermocouple Displays

Introducing the SRT-77 Temperature Meter: Precision Monitoring Made Simple

The SRT-77 Temperature Meter offers accurate temperature measurements with ease. Compatible with thermoresistance (Pt100/500/1000) and thermocouple (K, S, J, T, N, R, B, E) inputs, it suits various sensors. Enjoy precise readings with linearised measurements via polynomial characteristics. The thermocouple input expands diagnostics with a (-10…90 mV) measurement range. Benefit from a dual-row display, showing real-time values and programmed limits. Control heating/cooling processes effortlessly with 1 or 2 relay (or OC) outputs. Seamlessly integrate with production monitoring systems through RS-485 data transmission. Configure the meter via the local keyboard or free S-Config software using the RS-485 port. Experience simplified temperature monitoring with the SRT-77 Temperature Meter.

Product Highlights

The SRT77 Process Meter is a versatile temperature meter designed for precise measurements in various industrial applications. It offers a single input for thermoresistance (Pt100/500/1000) or thermocouple (K, S, J, T, N, R, B, E) sensors. The meter incorporates polynomial characteristics for linearising the measurement data, ensuring accurate and reliable results. Additionally, for diagnostic purposes, the device equipped with a thermocouple input features an extended measurement range of -10 ÷ 90 mV. One of the key advantages of this meter is its dual-row display, where the first row presents the measured value, and the second row showcases the programmed values, such as maximum and minimum thresholds. With one or two relay (or OC) outputs, the SRT77 enables efficient control of heating or cooling processes. It supports data transmission through the RS-485 interface, facilitating integration into production process monitoring systems. The meter’s REL/OC control outputs allow adjustment of the measured signal level based on one or two threshold values. Configuration of the meter can be done through the local keyboard or the S-Config software, utilising the RS-485 communication port for seamless setup.
