Product Description

Overview

The HT219M on-site display temperature transmitter receive signals from thermal resistors(RTD) and thermocouples(TC) and convert the input into 4-20mA, RS485 or HART signals that are linearly related to temperature.

Product Features

 

• Widly input signal: 2 kinds of RTDs, 10 kinds of thermocouples
• 4~20mA output, RS485,HART optional
• Thermocouple cold-end compensation
• Response time≤700mS
• Input and output isolation(for choice), good anti-interference effect
