Product Highlights

The SUR94 meter is a versatile instrument with a universal input accepting signals like 0/4-20 mA, 0-10V, 0-150 mV, Pt 100/500/1000, or TC (K, S, J, T, N, R, B, E). It automatically compensates for cold end temperatures and provides fully linearised characteristics for RTD and TC inputs. The meter offers various characteristic curves, including linear, square root, quadratic, user-defined, and volume characteristics for cylindrical tanks. It features a 24V DC / 100 mA output for transducer supply and an RS-485 port for data transmission in production process monitoring systems. The REL / OC control outputs enable precise signal adjustment based on threshold values. Analogue outputs, such as active current output, passive isolated current output, or active voltage output, can be added. Configuration is possible via the local keyboard or free S-Config software using the RS-485 communication port. The SUR94 meter is a reliable and flexible solution for process control systems, offering accurate measurements and adaptable functionality.
