SRP-94 / SRP-946

The SRP-94(6) meter is designed for measuring of typical current or voltage signals. The readouts are presented on well-readable display with standard range of four digits or five/six digits for more demanding applications (e.g. measurement range: 4 – 20 mA, indications range: 0 – 20 000 kg). Thanks to wide range of characteristic curves (linear, square root, quadratic, user-defined and volume characteristic for cylindrical tanks) the meters may be used in various process control systems. The 24V DC / 100 mA output is designed to supply measuring transducers, and the RS-485 port enables data transmission in production process monitoring systems. The REL / OC control outputs can adjust the level of measured signal and are controlled according to one or two threshold values. Moreover, the meter can be equipped with analogue outputs, according to the customer selection: active current output, passive isolated current output or active voltage output. The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port
