Ztech’s digital Universal dual channel process indicator model ZT502 is designed to indicate process parameters like temperature, level, flow, pressure etc as per the process requirement for various applications. It can display the process value with the resolution of maximum 4 digits. The range is selectable from -1999 to 9999 scale with selectable decimal resolution. It can generate max two relay output (on/off on each channel) for various application with hi/lo selection. The hysterisis is programmable through out the range. It can generate analog output as retransmission & give computer connectivity port on Modbus protocol or GSM connectivity as an optional feature. They are very reliable, accurate employing the latest technology. They undergo stringent tests to assure quality performance.
