The SRP-N118 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. Thanks to the tight housing with high (IP 67) protection degree, this device is particularly suitable for operations in harsh environments. Wide range of characteristic curves (linear, square root, quadratic, user-defined and volume characteristic for cylindrical tanks) allows the use of meters 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 may be configured with no need to open the case, by using the remote controller or with free S-Config software via the RS-485 communication port.
