DIGITAL TEMPERATURE SENSOR
User Manual for SRTH600-901-2401 & 2402
Product Description
The digital temperature sensors converts physical quantity of temperature into digital quantity
(RS485). The data can be read by data acquisition equipment such as computers, PLCs, and
smart meters through the corresponding circuit.
The digital temperature transmitter consists of a temperature measuring probe, a temperature
conversion component, and a protective shell. The products are widely used in temperature
measurement process control in petrochemical, electric power, metallurgy, medicine, food and
other industrial fields, and cooperate with meters or PLC to form a computer distributed
measurement and control system.
Features
Efficient lightning protection, anti-radio frequency and electromagnetic interference
protection
Fast response and high accuracy
Gas-liquid dual purpose, any medium compatible with 304
Digital signal RS485 output
