DAT intelligent temperature controller with industrial heat resistance, even for temperature sensing element, the CPU after the output switch contact signal, RS485 communication signal, 4 ~ 20mA and other signals. Controller is a fully digital product, the main features are used for all digital electronic circuit design, operation by touch of a button, greatly facilitate the user-site operation, ultra-bright display and large digital measurement alarm status display easier to observe the temperature conditions. The product uses advanced temperature compensation technology to ensure that products in a relatively poor working conditions can still maintain excellent sensitivity, linearity and stability.
