dopressure transmitterProvide a power circuit for the primary instrument that requires on-site power supply, and measure the current signal output by the primary instrument online. After processing such as calculation and interference suppression, transmit isolated single or dual current or voltage signals to improve the electrical isolation performance between input, output, and power supply.
Universal intelligent distributorTechnical features:
This product uses advanced digital technology, has many advanced properties that traditional analog distributors do not have, and has excellent performance in suppressing high and low frequency interference signals. It can still be reliably applied even in high-power frequency conversion control systems. It uses digital calibration, zero free and full potentiometer, automatic dynamic calibration zero, automatic compensation for temperature drift, short circuit of distribution power supply and input reverse connection protection functions and many other advanced technologies internally, and meets the requirements of the fourth class (harsh industrial site) environment specified in IEC61000-4-4:1995 for anti electromagnetic interference of products. The application of this series of technologies ensures the stability and reliability of products scientifically.
Universal intelligent distributorApplicability:
It can be used in conjunction with unit combination instruments and DCS, PLC and other systems, and has a wide range of applications in major projects in industries such as oil fields, petrochemicals, manufacturing, power, metallurgy, etc.
Technical parameters of universal intelligent distributor:
System transmission accuracy: ± 0.1% × F • S
Temperature drift: ± 0.0035% × F • S/℃ (35ppm/℃)
External power supply voltage: no more than 28V when unloaded, and no less than 20V when fully loaded.
Input impedance: Current: ≤ 60 Ω; Voltage: ≥ 500KΩ
Output state when input signal is disconnected:
There are two output states that can be set: follow mode and alarm mode.
