Sell rs485 integration of multi-channel temperature transmitter @China (Mainland)

This transmitter which is way temperature transmitter, the industrial standard RS-485 bus, Modbus agreement with output, able to connect a variety of external equipment or PC.

Product description

Integrated multi-channel temperature transmitter is there for many thermal resistance occasions design of data collection and control of a miniature far move device. In the design adopted our company's unique bridge circuit measurements technology, with no temperature drift, no influence lead resistance, strong anti-interference, electric bridge circuit and measurement circuit complete isolation, and many other advantages. Using aluminum alloy waterproof box of design, and contains with metal, radio frequency interference resistance, and corrosion resistance. TanGan temperature stainless steel TanGan design, the circular explosion-proof headers, strong, corrosion and durable, strong anti-jamming, work humidity range.
