Ztech Instruments

We manufacture, supply and export a wide variety of controllers that have a wide application in various industries such as steel, pharmaceuticals, fertilizers, chemicals, power, cement and paper industry. These controllers are well appricaited by our clients for its high conductivity and efficiency across the globe.

The types of controllers offered by us are as follows:

•    Universal Input on/off controllers
•    Dual Channel universal input on/off controllers
•    Conductivity Type Level Controllers
•    Digital Timers (on/off, Cyclic and Sequential)
•    PID Controllers

Ztech’s Digital Universal Indicator Controller model ZT501 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 or 5 (optional) digits. The range is selectable from -1999 to 9999 scale with selectable decimal resolution. It can generate max four relay output (on/off) for various application with hi/lo selection. The hysteresis 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.
