Digital Temperature Transmitter TMD-21<\/h2>\n

TMD-21<\/strong> is a modern temperature transmitter designed to work with thermoelectric sensors (thermocouples). It enables precise temperature measurement and easy configuration via the RS-485<\/strong> interface using the MODBUS-RTU<\/strong> protocol. It can be integrated with any automation system based on the RS-485 bus and Modbus-RTU protocol.<\/p>\n

Our transmitter offers, among others:<\/strong><\/p>\n
