Process indicator SUR-94 series

ratespeedtilt

The SUR-94 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. Temperature of cold ends is compensated automatically. RTD and TC inputs feature with fully linearized characteristics. 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. Output type - depends on configuration: relay I=1A, U=30V DC/250V AC (cosø=1) Open Collector: I=30 mA, U=30V DC, P=100 mW 0/4...20 mA: active current, operating range 0...24 mA max., load resistance 700 Ω max., resolution 13 bit 4...20 mA: passive current, isolated, operating range 2,8...24 mA max., load resistance 600 Ω@24VDC, resolution 13 bit 0/1...5V, 0/2...10V: active voltage, operating range 0...11V max., load resistance min. 2000 Ω, resolution 13 bit
