The Simex SUR-457 universal meter is built into tight, wall-mounted housing with large 57 mm LED display.
The SUR-457 meter is equipped with one universal input, type: 0/4-20 mA, 0-10V, 0-150 mV, Pt 100/500/1000 or TC (K, S, J, T, N, R, B, E). During the measurement process only one kind of input is available.
As a main advantage, this device is equipped with a large, 57 mm high display offering ultra bright red, green and blue as well as multicolour LED’s.
Thanks to the tight housing with high (IP 67) protection degree, this device is particularly suitable for operations in harsh environments.
Due 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 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.
