The temperature transmitters could be divided into three categories:
- 2 wires transmitters : the power supply and the output are on the same line
- 3 wires transmitters : the power supply and the output have just one common wire.
- 4 wires transmitters : the power supply and the output are completed isolated between themselves.
Further than the versions with galvanic isolation between transmitter input and output and the versions with intrinsic safety, because of the new constructive technologies, TERMOTECH is able to supply as well transmitters with special functions as:
- Complete programmability of all parameters (range, input sensor type, etc.) trough computer.
- Possibility of constantly monitoring the thermoelement isolation resistance at his input.
- Possibility to have a frequency signal on the same line of the analogue one, that permits to control and modify all parameters trough modem.
