Through 30 years experience and innovation, Suntex has launched its fifth generation transmitter. We called it intelligent transmitter series. The intelligent transmitter series includes pH/ORP, Conductivity/Resistivity, Dissolved Oxygen, Residual Chlorine, Turbidity, Ion and Specific Gravity models for water treatment & process. The intelligent transmitter features 1/4 DIN or 1/2 DIN housing with IP65 protection, graphical menu, last calibration and overview of setting at a glance, and auto-sense backlight display, etc. There are also RS-485 Modbus models and PID controlling models to satisfy various demands. All of them are the proof of our continuous research and development to make the online measurement and controlling easier and more reliable.

There are four major elements to make a complete measurement system.
1. Transmitter: to translate the sensor’s reading into a displayed measurement and transfer the data to the process control system
2. Sensor: directly mounted in the field to measure solutions

3.Cable: to transmit the signal between a sensor and a transmitter
4.Sensor Housing: to hold the sensor, protect the sensor in the measurement solutions, and to connect to the extension cable
