Detailed Description

Description ACT-302 Digital Temperature Transmitter adopts imported temperature-sensing elements. The product performance is remarkable, with longer service life, higher measurement precision, longer stability and less maintenance. When standard analog signal output, various communication interfaces of the product can be expanded. The product is ideal substitute of general temperature transmitter. Applications  Substitute of imported temperature transmitter instrument  Temperature monitoring and remote transmission for oil well and gas well.  Applicable for temperature parameters network acquisition in large area. Features  Measuring range can be shift, and the recommended shift shall not exceed3:1  With RS485 communication and 4~20mA current output  Output current resolution radio can be up to 3uA  Always online communication technology, bus supports 255 devices with RS485  Unique anti-radio frequency technology, to ensure safety of instrument work  Enhanced lightning protection technology, to ensure safety of instrument work  Epoxy sealing structure, which can ensure the temperature-sensing elements can be fully contacted with measured temperature field. The temperature response is fast to reveal the true value of measured temperature field.  The aluminum alloy shell is strong and shock resistant, with explosive-proof function. Data Sheet 1.
