Pt100/Cu50 RTD to Frequency Isolated Signal Transmitter IC

 SunYuan ISO Z-W-P-F series isolation transmitter IC is a kind of Pt100/Cu50 RTD sensor analog signal according to the temperature detection high and low isolation converted into a digital pulse frequency signal mixed IC which is linearly proportional to the temperature change.  The IC will transform the RTD signal into unit pulse frequency signal and then isolate the output, which can significantly enhance the signal anti-jamming ability, and is conducive to long-distance distortion-free transmission. Through the counter interface with microcontroller, the product can finish AD conversion and RF signal modulation wireless remote transmission, and can also be combined with optical transceiver module for fiber optic remote transmission.

        Module internal integration of high-efficiency DC-DC, can generate two groups of mutually isolated power supply to the internal input side of the RTD long line compensation circuit, linearization processing circuit, voltage amplification and adjustment circuits, precision voltage and frequency conversion circuits, frequency divider circuits, isolation of anti-jamming suppression circuits, and the output side of the output circuits power supply, respectively. Particularly suitable for the isolation of RTD signals into digital pulse frequency signals, temperature signal transmission and distortion-free remote transmission, industrial field PLC or DCS system temperature signal acquisition and isolation. The internal SMD process structure and new technology isolation measures enable the device to achieve: working power supply/signal input/output 3000VDC triple isolation, and can meet the industrial grade wide temperature, humidity, vibration of the site of the harsh operating environment requirements.

        ISO Z-W-P-F series temperature signal isolation amplifiers are very easy to use, users only need to connect the external zero and fullness potentiometers for calibration to realize the isolation of Pt100 RTD sensor signals into unit pulse frequency signal isolation transmission. The products can be customized according to the user's industrial site custom parameters requirements, the mounting method is standard SIP 16Pin PCB board soldering mounting or standard DIN 35 Rail-mounted.Especially suitable for instrumentation and industrial control intelligent industry remote telemetry telecontrol equipment in the frequency and phase modulation, AD conversion, GPRS/GMS wireless digital transmission, digital temperature meter, data measurement instruments and other needs to realize the Pt100 RTD signal isolation and transmission of the occasions, and can realize the industrial field temperature control signals long-distance transmission of a one-in-one-out, two-in-two-out function. The products are widely used in metallurgy and mining, petrochemical industry, electric power equipment, medical instruments, industrial automation, new energy facilities and military scientific research, etc. Users can choose the appropriate products according to the needs of the site.
