MTR264 – Nokeval

4-channel transmitter for hermocouples

The MTR264 is a battery powered, 4 channel wireless transmitter. It is housed in a compact plastic enclosure and equipped with a 6-terminal detachable screw post connector.

It has an internal circuit board antenna for a radio coverage area of up to 100 meters in free space. The wireless concept allows easy implementation, installation and expansion of a measuring system even in difficult locations and installation sites. The transmitter is programmable for transmission intervals from 5 seconds to 5 minutes and for millivolt and thermocouple inputs. If thermocouple input is used, the result is sent in millivolts. In addition, the device measures and sends the cold junction temperature. The result is linearized in the receiving system (for example, in the Ovaport Web Service).
