Standard assembly consists of the metal alloy protection tube with a general purpose aluminum connector head attached.The connector head has a 1/2” inch NPT outlet port. This unit is assembled with a heavy gage ungrounded thermocouple with ceramic insulators and is connected to a two-wire terminal block in the connector head. This unit can be combined with cold leg extension assembly if necessary. For special designs or requirements contact us.
Summary
RTW series temperature transmitters are scene installation temperature transmitter units to be used to measure the temperature of the gas,liquid and so on between－200℃ and ＋1600℃. They adopt two-wire way, output the current signal of 4 to 20mA, can be used in the junction box or fixed in the instrument box.
The products have already extensively applied in the petroleum, chemistry industry, metallurgy, electric power, light industry, textile industry, food processing etc. and can be used with instrument, recorder and computer to be a temperature control system.
