Temperature Transmitter

100+

50-65 USD

Introduction:
- Smart digital display temperature transmitter which is suitable for resistance temperature detectors (RTDs), thermocouples (TCs), resistance and voltage signal input through the HART protocol configuration and that sensor input and signal output digital isolation, as well as high-resolution, high-precision, ultralow power consumption
- Product module uses 24-bit sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), electrical isolation (isolation voltage up to 2kV), to ensure the transmitter stable in interference environment, also using ultra-low power MCU with built-in cold junction compensation to achieve signal filtering, amplification and linearization
- LCD display with backlight has both Chinese and English language operation menu function which makes field measurements more intuitive and convenient
- Transmitter features wide measurement range and high accuracy, in the industrial field 4-20mA signal output directly, so widely used in the petrochemical industry, electric power and metallurgy
Applications:
- Standard RTDs and TCs
- Ohm and mV signal
- Two wire 4-20mA current loop and HART
- 2, 3 and 4-wire RTD input
Main features:
- Electronic isolation
- HART communication, easy for configuration and calibration
- Resistance to industrial frequency interference
- Built-in cold junction compensation
- Support for multiple temperature sensor input
