Description

TRIS is a programmable transmitter that converts signals from various sensors into a digital code transmitted over an isolated RS485 interface. Compatible with up to 32 devices in a network, it supports universal input for RTD, thermocouple and linear signals, providing precise monitoring and data recording in industrial applications. The transmitter allows the user to:

  • select the type of sensor and input signal (4 RTDs, 6 thermocouples and 4 linear signals);
  • select and set the input range;
  • enter zero correction and calibrate the output;
  • select the unit of measurement and the position of the decimal point;
  • set digital filters.

 

TRIS Applications:

TRIS is widely used in industrial monitoring and control systems, where data collection from multiple points is required via a single communication line. Thanks to its universal input and networking capabilities, the transmitter is suitable for:​

  • Automation of production processes: Collection and transmission of data from various sensors for production optimization.​
  • Energy: Monitoring of temperature and other parameters in energy installations.​
  • Chemical industry: Monitoring of critical processes by integrating multiple sensors into a network.​
  • Food and beverage industry: Control of parameters such as temperature and humidity in production and storage facilities.​
  • Environment: Collection of data from sensors for monitoring environmental indicators.

The flexibility and reliability of TRIS make it a valuable tool for building effective and scalable monitoring and control systems in various industrial sectors.
