Product Introduction
ACT-201 is increased with remote transmitting module based on the traditional field display temperature gauge of ACT-200. The available communications are RS485, USB , （4~20）mA current signal output, etc. Coordinating with the communication software, ACT-201 can directly communicate with the computer for the detection of data storage, processing and report output. Using signal isolation design, eliminate interference. Built-in lithium battery can serve for 5～8 years, it can acquire constantly and stably( communication function failure ) when the external power off. Installations can be radial, axial and reel packing for your choice.
