Product Description

Product Overview:
 

HT218M  LCD isolation intelligent temperature transmitter is used for RTD, thermocouple (TC), resistance  (Ω),   signal  input,  two-wire  system  4-20mA  analog  output,  and  the configuration is via RS485 (MODBUS RTU protocol) or HART protocol.


Features:

• Input signal supports 2 RTDs, 10 thermocouples
• Input signal is fully switchable
• 4~20mA output, RS485,HART optional
• Thermocouple cold end compensation
• Response time≤700mS
• Input and output isolation, good anti-interference effect

Note:

1. The above accuracy data is tested under the condition of ambient temperature of 20ºC±2ºC.

2. The output accuracy "%" is relative to the set range.

3. Thermocouple measurement also need to add the cold end compensation error, internal cold end compensation error ≤ ± 1 ºC.
